When you visit a modern website in Chrome, Firefox, or Edge, the browser sends an HTTP Accept header with every image request that lists the formats it can decode. This header is part of the HTTP content negotiation mechanism and tells the server which image formats are acceptable for the response. Chrome and other Chromium-based browsers include "image/webp" in this header, signalling to the server that WebP is acceptable for the response. Web servers configured for performance, including most CDNs, Google infrastructure, and sites using image optimisation services like Cloudflare Images, Imgix, Akamai Image Manager, or Fastly Image Optimizer, respond by serving the WebP version of the image when one is available. The HTML source code of the page may still reference a .png or .jpg URL because the URL preserves the original source filename, but the actual bytes delivered to your browser over the wire are WebP encoded.
When you right-click an image and choose "Save image as," Chrome saves the actual file the browser received from the network response, which is WebP, but uses the filename derived from the URL path. If the URL ends in .jpg, Chrome may name the saved file image.jpg even though the content inside the file is a WebP-encoded image. This creates significant confusion in practice: users see a .jpg filename in their Downloads folder and assume the file is JPEG, then encounter cryptic errors when image editors report an unsupported file or fail to open it, or notice that the file is reported as WebP when its properties are inspected. The same mismatch happens when downloading linked images through "Save link as," because the downloaded bytes are whatever the server chose to deliver based on the Accept header, regardless of what the URL extension implies about the format.
The right-click "Copy image" option in Chrome behaves differently from "Save image as." Copy image transfers the decoded raw pixel data from the browser to the system clipboard as a bitmap, rather than the WebP file from the network response. As a result, pasting into Microsoft Paint, Photoshop, Word, or other applications that accept clipboard images works correctly without any format error, because the clipboard contains decoded pixels rather than encoded WebP bytes. However, this method does not save a reusable file you can attach to email, upload to a CMS, or reference by filename across applications. Saving via right-click is the preferred approach when you need a portable image file rather than a one-shot paste.
After saving the WebP file from your browser, open FixTools in any browser tab, upload the saved file from your Downloads folder by dragging or selecting it, choose PNG as the output format, click convert, and download the result. The conversion runs locally in your browser using the Canvas API and takes well under a second per file on a modern device. The resulting PNG is a clean lossless file with the correct .png extension and the same alpha transparency as the source WebP, suitable for any downstream use including design software, email attachments, document insertion, CMS uploads, and archival storage. FixTools detects WebP even when the saved file carries a misleading .jpg or .png extension, so no renaming or extension correction is required before uploading.
Upload the WebP file you saved from your browser, select PNG output, and download a clean PNG you can open in any application. Works for images saved from any website in Chrome, Edge, or Firefox.
Step-by-step guide to save webp as png from browser:
Save the image from your browser
Right-click the image on the webpage and choose "Save image as" from the context menu, then pick a destination such as your Downloads folder and confirm the save. The file saves to disk, very likely as a .webp file with that explicit extension, or as a misleadingly named .jpg or .png file that contains WebP bytes inside. Either way, the saved file is the WebP that your browser received over the network from the server.
Open FixTools Image Format Converter
Open fixtools.io in any modern browser on the same device, then navigate to the Image Format Converter section of the site. The converter loads as a regular webpage with no installation, no account, and no setup. It works in Chrome, Firefox, Safari, Edge, and other modern browsers on Windows, macOS, Linux, ChromeOS, iOS, and Android devices alike, so the same workflow applies whether you saved the image on a desktop or a mobile device.
Upload the saved WebP file
Upload the image from your Downloads folder by clicking the upload area to open a file picker or by dragging the file directly onto the tool from your file browser. FixTools detects the actual WebP format by reading the file signature from the first few bytes of the content, even if the filename extension says .jpg or .png because the source URL had that misleading extension. No manual renaming, conversion, or extension fixing is required as part of preparation.
Select PNG as output
Choose PNG from the output format dropdown selector. PNG is a lossless format that preserves every pixel from the WebP source exactly, and it also supports the same alpha transparency channel that WebP uses, so any transparency in the original is carried through into the output file. PNG is the most universally compatible target format and opens in every operating system, design tool, document editor, and image viewer made in the last twenty years without compatibility issues.
Convert and download the PNG
Click the Convert button, wait briefly while the browser decodes the WebP and re-encodes it as PNG using the HTML5 Canvas API, then click Download to save the PNG to your device. The resulting file opens correctly in Photoshop, Affinity Photo, Word, PowerPoint, Paint, Preview, Figma, and any other application that accepts standard image files. The PNG has the correct .png extension, preserves transparency, and contains no watermark, branding, or quality loss from the conversion.
Common situations where this approach makes a real difference:
Saving a product image from a retail website
A user saving a product photo from an e-commerce site such as Amazon, Etsy, or a brand storefront to use in a comparison document or a personal review finds that the saved file is WebP and does not open in their older version of Microsoft Office. They need the image embedded in a Word document or PowerPoint slide for a presentation, but Office throws an unsupported format error. Converting the file to PNG in FixTools takes under twenty seconds end to end. The resulting PNG opens immediately in Word and PowerPoint without any compatibility issues, plugins, or Office updates.
Designer saving reference images from competitor sites
A UX designer building a competitive analysis deck saves screenshots and UI reference images from competitor websites in Chrome during a research session, ending up with thirty or forty saved images. All of them are WebP because the target sites use modern CDNs that serve WebP to Chrome. Batch uploading a session's worth of saved images to FixTools at once converts the entire set to PNG in a single operation, producing a folder of editable reference images ready to drop into Figma or Sketch as design brief context layers without any per-file manual conversion work.
Blogger saving a news photo to accompany an article
A blogger saving an image from a news site to use in a commentary article about that news finds the saved file is .webp and cannot be uploaded to their older WordPress media library. WordPress rejects the upload with a generic "file type not allowed" error that does not explain the actual WebP cause. Converting the WebP to PNG in FixTools resolves the upload error immediately. The PNG is accepted by the WordPress media library without any WordPress plugin installation, theme update, or setting change, and the article is published on schedule with the supporting image.
Student saving diagrams from academic websites
A graduate student saving figures, scientific charts, and process diagrams from academic websites, journal pages, and university course materials for a research presentation finds that the saved files are WebP, which the version of PowerPoint installed on their university-provided laptop does not accept. The university IT policy prevents installing software updates without an approval ticket. Converting all the saved files to PNG in FixTools gives the student compatible image files that insert cleanly into slides with no distortion, format error, or workaround, and works entirely within the browser without requiring any software installation.
Get better results with these expert suggestions:
Check the actual file type, not just the extension
Files saved from Chrome and other modern browsers may have a .jpg or .png extension but contain WebP data inside, because the saved filename comes from the URL path while the bytes come from the network response. If an image fails to open in your application with a generic format error, right-click the file and choose Properties on Windows or Get Info on Mac to check the actual file kind reported by the operating system. If it says WebP, convert the file using FixTools before attempting to open it in the target application rather than wasting time troubleshooting the application itself.
Use "Copy image" in Chrome as a quick alternative
In Chrome, right-clicking an image and choosing "Copy image" places decoded raw pixel data on the system clipboard rather than the WebP file from the network response. You can paste this directly into Paint, Photoshop, Word, Affinity, or any application that accepts pasted images, and the paste will succeed because the clipboard contains pixels rather than encoded WebP bytes. This bypasses the WebP file format entirely. To save the pasted image as PNG, paste it into Paint or Preview and use the Save As command to write a PNG file to disk.
Firefox and Edge also serve WebP for compatible images
The WebP saving behaviour is not specific to Chrome. Firefox has shipped WebP support since version 65 in early 2019, and Microsoft Edge has supported WebP since switching to the Chromium engine in 2020. Both browsers send WebP in their HTTP Accept header and receive WebP responses from servers that support content negotiation. Files saved from Firefox and Edge also arrive as WebP for images served by modern CDNs. The same FixTools conversion process applies identically regardless of which browser saved the original file, so the workflow generalises across all modern browsers.
FixTools detects WebP by file content, not extension
If a saved file has a .jpg or .png extension but is actually WebP, FixTools identifies the real format from the file bytes during the upload step by reading the file signature in the first few bytes of the content. You do not need to rename the file, change the extension, or perform any preparation step before uploading. The converter reads the actual file header and routes WebP content through the WebP decoding path regardless of what the filename says. This means saved files with mismatched extensions, which are very common from Google-served images, just work.
