iOS WebP Support: What Changed in iOS 14 and iOS 16

iOS gained WebP display support in Safari as part of iOS 14, released in September 2020 alongside the iPhone 12 launch. Before iOS 14, Safari on iPhone could not render WebP images at all, which meant websites had to detect iOS Safari through user agent sniffing or feature queries and serve JPEG or PNG fallbacks to keep the experience consistent for iPhone visitors. With iOS 14, Safari began rendering WebP inline just as it does on desktop macOS, and the same Chromium-derived WebP decoder used by every other major browser became part of the iOS web stack. This change had a knock-on effect: when users saved images from websites using the long-press Add to Photos gesture, the file saved into Photos in whatever format the website happened to serve, which on Chrome-detecting CDNs increasingly meant WebP rather than JPEG.

iOS 16 brought a more visible change for end users by giving the Photos app the ability to display WebP images natively. Before iOS 16, if you saved a WebP image from Safari into Photos through the share sheet, it might appear as a blank thumbnail in the Camera Roll, fail to render in the full-screen viewer, or refuse to show up in albums and Memories that depended on visual indexing. iOS 16 resolved this by adding WebP rendering throughout the Photos stack, including thumbnails, Quick Look, the full-size viewer, and Memories. However, even on iOS 16 and later, sharing a WebP from Photos to many third-party apps still results in the receiving app getting a JPEG conversion rather than the original WebP, because iOS applies format conversion at the Photos framework boundary when apps request a generic image type for compatibility.

In practice, WebP files that land in the Files app under Downloads rather than in Photos behave more predictably for downstream conversion. Apps that access Files directly through the document picker receive the WebP file as-is, complete with the original alpha channel and any ICC colour profile the source carries. For converting WebP files on iPhone, FixTools in Safari reads the WebP straight from your Downloads folder in the Files app and converts it to PNG entirely on-device using the canvas pipeline. The converted PNG downloads back to the Files app Downloads folder, from where you can move it to Photos with Save to Photos, send it through the system share sheet to any installed app, attach it to an iMessage or Mail draft, or upload it to iCloud Drive for syncing across your Apple devices.

There is also an iOS hardware angle to consider when converting larger WebP files on an iPhone. The HTML5 Canvas pipeline that FixTools relies on allocates memory proportional to the image's pixel dimensions multiplied by four bytes per pixel for RGBA, which means a 4032 by 3024 photograph from a recent iPhone uses around 48 MB of canvas memory during the conversion. On the iPhone 12 and later, Safari handles this comfortably because the device has 4 GB or more of system memory available. On older iPhones such as the iPhone 8 and iPhone SE first generation, Safari may evict the tab from memory during conversion of very large WebP files, in which case downsizing the image first using a desktop machine or processing batches of smaller files individually on the iPhone is the safer route. For typical web-sized images under 2 MP, every supported iPhone running iOS 14 or later handles conversion without any issue at all.

How to use this tool

💡

Open FixTools in Safari on your iPhone, tap to upload your WebP file from the Files app, select PNG output, and download the converted image.

How It Works

Step-by-step guide to convert webp to png on iphone:

1
Open Safari on your iPhone
Launch Safari from your iPhone Home Screen, App Library, or Spotlight search, and navigate to fixtools.io. Tap the Image Format Converter card from the homepage to open the tool. The interface adapts to the iPhone screen size and supports both portrait and landscape orientations, so you can rotate your device freely during the conversion if you prefer the wider layout for selecting files and inspecting the output preview before downloading.
2
Tap the upload button
Tap the Upload area inside the converter. When iOS prompts you for the file source, choose Browse and navigate to the Files app, where any WebP image you saved earlier from Safari, Mail, Messages, or a cloud service such as iCloud Drive or Google Drive will be listed. You can also use Photo Library if the WebP file is stored as a photo, although saving WebP into the Files app rather than Photos generally gives you cleaner access to the original bytes.
3
Select PNG as output format
Once the WebP file is loaded into the converter, choose PNG from the output format selector beneath the upload area. PNG is the default for lossless output on iPhone, preserves transparency from the source WebP, and is the right choice whenever you plan to share the converted image to apps such as Pages, Keynote, Canva, or any messaging app that prefers PNG over WebP for inline display and attachment compatibility.
4
Convert the WebP
Tap Convert. The image is processed entirely locally on your iPhone using the browser's native WebP decoder and the HTML5 Canvas API, so no data is sent over the cellular or Wi-Fi connection during this step. Typical conversion of a single photograph completes in under a second on any iPhone from the iPhone XR or later, and even high resolution images finish within a couple of seconds without any noticeable battery drain.
5
Download the PNG
Tap Download to save the converted PNG to your iPhone. The file lands in the standard iOS Downloads folder accessible through the Files app under On My iPhone, from where you can move it to iCloud Drive, share it through the system share sheet to any installed app, attach it to an email or message, or save it to Photos using the Save to Photos action in the long-press menu for use in Camera Roll-based workflows.

Real-world examples

Common situations where this approach makes a real difference:

iPhone user attaching an image to a support email

An iPhone user saves a product image from a brand website in Safari to include as evidence in a customer support email about a damaged delivery. The file arrives as WebP because the brand site serves WebP to mobile Safari, and the support team's email client cannot display the attachment inline, only as a generic file attachment with a broken thumbnail icon. Opening FixTools in Safari, converting the WebP to PNG, and re-attaching the PNG to the email takes under a minute and ensures the recipient sees the damage photo immediately when they open the message in any email client.

Blogger updating a site from an iPhone while travelling

A travel blogger saves reference images from news sites and tourism portals while travelling and discovers that every file downloads as WebP from mobile Safari. Their WordPress mobile app and the WordPress web editor in mobile Safari both reject WebP uploads to the older media library installed on their self-hosted site. Converting each WebP to PNG in FixTools through Safari produces compatible files the blogger uploads directly from the iPhone Files app to the WordPress editor, allowing them to publish a fresh post from the road without needing to return to a laptop to finish the workflow.

iOS 15 user whose Photos app shows blank thumbnails

A user still on iOS 15 because their iPhone 7 cannot upgrade to iOS 16 saves a WebP image to Photos from Safari and the thumbnail appears as a blank grey rectangle in the Camera Roll, with the full-screen viewer also failing to render the image. They open FixTools in Safari, upload the WebP from the Files app Downloads folder, convert it to PNG, save the resulting PNG to Photos through Save Image, and delete the blank WebP entry from Camera Roll. The PNG displays correctly in Photos thereafter and can be shared through the standard share sheet without further issues.

Pro tips

Get better results with these expert suggestions:

Save WebP from Safari to Files, not to Photos

When you long-press an image in Safari on iPhone, choose Save to Files rather than Add to Photos. The Files app stores the original WebP file with its bytes intact, including the alpha channel and any embedded colour profile, which gives FixTools clean source material to convert. Saving directly to Photos may trigger an iOS-level format conversion that creates a JPEG copy with lossy recompression, and that JPEG then sits in Camera Roll at a slightly lower quality than what you would get by converting the original WebP yourself with FixTools.

Find downloaded WebP files in Files app under Downloads

WebP files downloaded through Safari on iPhone appear in the Files app under On My iPhone then Downloads, regardless of whether you used the standard download flow or saved through a share sheet. If you cannot find a recently downloaded file in that location, check the iCloud Drive Downloads folder if iCloud is enabled, and also check the in-app downloads section of any third-party browser you may have used. From the Files browser you can upload the WebP directly to FixTools through the standard document picker.

iOS 16 and later: Photos app shows WebP natively

On an iPhone running iOS 16 or any later release, the Photos app can display WebP images correctly in the Camera Roll, the full-screen viewer, Memories, and shared albums. If you are on iOS 15 or earlier and a WebP saved to Photos shows as a blank thumbnail or fails to render in the viewer, convert it to PNG first using FixTools and then save the PNG to Photos instead. The PNG displays exactly like any other photo and integrates with every iOS feature that depends on visual indexing including Live Text, People recognition, and Search.

Share converted PNG directly from Safari Downloads

After downloading a converted PNG from FixTools in Safari on iPhone, tap the Downloads button shown as an arrow icon in the Safari address bar to surface the list of recent downloads. Tap the PNG entry to open it in Safari, then tap the share button at the bottom of the screen to send it directly to Messages, Mail, Canva, Pages, Instagram, WhatsApp, Slack, or any other installed app that accepts PNG attachments. The share sheet uses the same UTI for the converted PNG as it would for any other PNG, so every app behaves normally.

FAQ

Frequently asked questions

Yes. Open FixTools in Safari or Chrome on your iPhone and navigate to the Image Format Converter. Tap Upload, select your WebP file from the Files app document picker or from Photos if the file is stored there, choose PNG as the output format, tap Convert, and tap Download once the conversion finishes. No app installation is required at any stage, no account is needed, and no advertising or sign-up gate is shown during the workflow. The whole conversion runs entirely inside the Safari tab using your iPhone's own CPU, so it works on cellular data, on aeroplane Wi-Fi, and offline once the page has loaded.

WebP files downloaded from websites in Safari are typically stored in the Files app under On My iPhone then Downloads. Files saved from Mail attachments, Messages, or third-party browsers may be in app-specific folders that you can browse through the Files app sidebar. WebP files that you saved with the Add to Photos action live in the Photos app rather than Files, but on iOS 15 and earlier those entries may appear as blank thumbnails because Photos could not render WebP before iOS 16. The simplest place to look is the Files app Downloads folder, which is also where converted PNGs from FixTools land.

Yes. The PNG downloads to your Files app Downloads folder initially. To move it to the Photos app and have it appear in Camera Roll, open the Files app, locate the PNG, tap and hold it to bring up the context menu, then tap Save to Photos. Alternatively, tap the share button on the file entry and choose Save Image from the share sheet, which routes the file into the Photos library through the same mechanism Camera and other apps use. Once in Photos, the PNG behaves like any other photo and is included in Memories, People, and Search indexing.

iOS 14 and later support WebP rendering in Safari for any image served by a website, and iOS 16 and later additionally support WebP display inside the Photos app, including thumbnails, Quick Look, the full-screen viewer, and Memories. However, many third-party apps still expect JPEG or PNG and either reject WebP attachments outright or display them as broken images, so converting to PNG remains the most reliable way to share images you saved from websites with the broader iOS app ecosystem. The conversion adds no quality loss for lossless WebP and only the unavoidable existing artifacts for lossy WebP.

Yes. When the upload dialog appears in FixTools after you tap Upload, tap Browse to enter the Files document picker, then navigate to iCloud Drive from the sidebar to select WebP files stored there. The converter works equally well with files from iCloud Drive, on-device storage, third-party cloud providers such as Google Drive or Dropbox that have integrated with Files, and any other Files-compatible location. After conversion the resulting PNG can be saved back to iCloud Drive directly from the Files app for syncing across all your Apple devices.

This is a known issue on iOS 15 and earlier where the Photos app cannot render WebP files because the Photos rendering pipeline did not include a WebP decoder before iOS 16. The file itself is intact and contains valid WebP bytes; only the visual preview generation is failing inside Photos. On iOS 16 and later this is fixed across thumbnails and the viewer. If you are on an older iOS version that cannot upgrade, use FixTools to convert the WebP to PNG, then save the PNG to Photos through the share sheet, and it will display correctly in Camera Roll and every Photos feature.

Yes. FixTools works in Chrome, Safari, Firefox, Brave, Edge, and any other browser on iPhone. On iOS, all browsers are required by App Store policy to use the WebKit rendering engine under the hood, which means WebP decoding, Canvas API behaviour, and download handling are essentially identical across browsers. The user interface differs cosmetically between browsers but the conversion result is the same. Safari is the most lightweight choice because it is preinstalled, but Chrome on iPhone is a fine alternative if you already use Chrome for syncing tabs with a desktop machine.

Once the FixTools page has finished loading in Safari or another iPhone browser, the conversion itself runs entirely locally on your iPhone and does not require an active Wi-Fi or cellular connection. The browser only needs the network the first time to fetch the HTML, CSS, and JavaScript that make up the page. After that you can put your iPhone in Airplane Mode and continue converting files, although navigating away from the page or fully quitting Safari will require a connection to reload the tool. iOS may also cache the page for short-term offline use depending on storage availability.

Yes. If the source WebP contains an alpha channel for transparency, which is common for logos, icons, and UI graphics, the PNG output preserves that channel exactly with 8 bits of alpha precision. The PNG can be placed over any background in apps such as Canva, Pages, Keynote, Procreate, Affinity Designer on iPad, or Photoshop on iPad, and the transparent regions will remain transparent rather than being filled with a default white background. This is the main reason to choose PNG over JPG when converting WebP on iPhone for design or asset creation workflows.

Yes. The Files document picker on iOS supports selecting multiple files at once: tap and hold the first WebP, then tap each additional file to add it to the selection before tapping Open. FixTools then processes the entire batch in parallel inside the Safari tab and offers a single Zip archive download containing all the converted PNGs with original filenames preserved. Batch sizes of 10 to 20 typical web-sized images convert smoothly on any recent iPhone, while very large images or much larger batches may slow down on older iPhones with limited memory.
