There is an important distinction between converting lossless WebP and lossy WebP to PNG that often gets glossed over by quick-answer tutorials. Lossless WebP stores every pixel value exactly, so converting it to PNG produces a mathematically identical image. Lossy WebP, on the other hand, works by discarding some image data during the encoding step, using a block-based discrete cosine transform that is similar in principle to what JPEG uses but more efficient. Once that data is discarded, it cannot be recovered. Converting a lossy WebP to PNG gives you a lossless copy of the already-compressed lossy image, not a restoration of the original uncompressed photograph. The PNG output preserves every artifact in the WebP exactly, neither adding new degradation nor reversing the degradation that already exists.
This distinction matters most when you receive a WebP file from someone else and need to edit it. If the file is a product photo that was compressed as a lossy WebP at quality 80, the PNG you get from the conversion will be pixel-perfect relative to that lossy WebP, but the compression artifacts already baked into the WebP, such as DCT blocking around high-contrast edges and subtle chroma smoothing, will still appear in the PNG. The PNG conversion adds no further degradation, but it also cannot undo what the lossy encoding already did. If you need the original uncompressed photograph for high quality print work or detailed retouching, you need access to the source file, typically a RAW, TIFF, or high-quality PSD from the original creator, not just the WebP that the website happens to serve.
In practice, most WebP files on the open web are lossy and are usually encoded at quality settings between 75 and 85. At those settings, artifacts are minimal and effectively invisible at the resolutions and viewing distances people actually consume web content. For logos, icons, and UI graphics, WebP is more commonly used in lossless mode because exact colour fidelity matters for brand work, and in that case conversion to PNG is genuinely lossless from end to end. You can check whether any given WebP is lossless or lossy by examining the file header in a hex editor or with a command-line tool such as ExifTool: lossless WebP files contain the byte sequence VP8L starting at offset 12, while lossy WebP files contain VP8 (with a trailing space) at the same offset.
Knowing whether the source is lossy or lossless helps you set realistic expectations for the conversion. If you receive a WebP brand asset from a developer and the file header indicates lossless encoding, the PNG you produce in FixTools will match the original developer source exactly and is suitable for high-fidelity work including print proofs and colour-managed design reviews. If the WebP is lossy, the PNG is still the best representation you can extract from that file but you should treat it as the production-quality version rather than the master, and ask for the original source if your downstream use is sensitive to compression artifacts. In either case, the PNG is far more portable than the WebP across the wider set of tools, email clients, and platforms you may need to send it through.
Upload your WebP image and select PNG as the output format. Conversion happens in your browser and the resulting PNG retains all image data including transparency.
Step-by-step guide to webp to png converter:
Open the WebP to PNG converter
Click the button at the top of this page to open the FixTools Image Format Converter. The page loads in under two seconds on a typical connection and the converter interface is available immediately, with no warm-up time, no plugin install prompt, and no permissions dialog beyond the standard browser file picker, which only triggers when you actually upload a file.
Upload your WebP image
Click the upload area to open the system file picker, or drag your WebP file directly from your Desktop, Downloads folder, Finder, or File Explorer window onto the converter. You can also paste an image from your clipboard if your browser supports it. The converter recognises WebP files even when they have a mislabelled .jpg or .png extension because it reads the actual file signature rather than relying on the filename.
Select PNG as output
Choose PNG from the output format options. PNG is the default for lossless output and is the right choice whenever you need transparency, exact pixel reproduction, or maximum compatibility with editing software. If you change your mind you can switch the output format before clicking Convert without re-uploading the file.
Convert and download
Click Convert and download your PNG file. The conversion completes almost immediately for typical web-sized images and within a couple of seconds even for high resolution photographs. Your PNG saves directly to your default Downloads folder, ready to open in Photoshop, Word, Preview, Paint, or any other application that handles standard PNG files.
Common situations where this approach makes a real difference:
UX designer working with downloaded production assets
A UX designer downloads forty or so component screenshots from a live production site to annotate in Figma during a heuristic review, but every saved image arrives as a WebP because the CDN serves WebP to Chrome. Converting the entire batch to PNG in FixTools takes one upload and one click, produces lossless files that import into Figma correctly, preserves the original 2x pixel density of the source assets, and gives the designer a clean set of reference overlays for design frames without any colour, transparency, or scaling issues during the rest of the project.
Marketing coordinator preparing a brand audit document
A marketing coordinator assembling a competitor brand audit across fifteen brands saves logo, banner, and product hero images from each company's website, receiving WebP files throughout because every modern marketing site optimises for page speed. Converting all of them to PNG in one batch operation gives the coordinator a consistent set of lossless assets that insert cleanly into a Google Slides deck, render correctly on the projector during the leadership review, and can be shared with the in-house creative team without any compatibility back-and-forth or version mismatches across operating systems.
Podcast host extracting guest headshots from a website
A podcast producer saves a guest speaker's headshot from the guest's personal website for use in episode artwork and social promotion, only to discover that the file is WebP and the studio's licensed copy of Photoshop 2020 returns an error when the producer tries to open it. Converting to PNG in FixTools takes seconds, runs locally so no third party ever touches the guest's image, and produces an editable file the producer can open, mask, composite into the episode thumbnail, and export at the dimensions required by the podcast hosting platform without any further format gymnastics.
Get better results with these expert suggestions:
Distinguish lossless vs lossy WebP before editing
If image quality matters for your project, check whether the source WebP is lossy or lossless before you spend time editing the converted PNG. Open the file in a hex editor such as HxD on Windows or Hex Fiend on Mac, or use a command-line tool like ExifTool, and look at bytes 12 through 15. Lossless WebP files contain the ASCII sequence VP8L at that offset, while lossy files contain VP8 with a trailing space. This single check tells you whether your PNG will be a true pixel-perfect copy or just a lossless snapshot of an already lossy source.
PNG is not always the right output for photos
For photographic WebP files, converting to PNG often produces files that are several times larger than the source, because PNG compression is not tuned for continuous-tone images with gradients and noise. If you need to share or upload a converted photograph and you do not need transparency in the result, convert to JPG at 85 to 90 percent quality instead. The JPG file will typically be 60 to 70 percent smaller than the equivalent PNG, with no visible quality difference at normal screen sizes, and it will fit comfortably inside email and CMS attachment limits.
Use PNG for graphics and icons, JPG for photos
As a practical rule of thumb, convert WebP logos, app icons, UI screenshots, diagrams, charts, and any graphic that includes transparency or sharp edges to PNG, where lossless compression preserves the crisp pixel boundaries that JPG would otherwise blur. Convert WebP photographs, product hero shots, lifestyle photos, and scene images to JPG, where DCT compression handles continuous tones efficiently. This split aligns each output with the format's strengths and keeps both quality and file size manageable across your asset library.
Transparency is lost when converting to JPG
If the source WebP has a transparent background and you convert to JPG, the transparent pixels become solid white because JPEG has no alpha channel and must replace transparent areas with an opaque colour. Always preview whether the source file has transparency before choosing the output format. The FixTools converter shows a checkerboard pattern under transparent regions in the preview thumbnail, which makes it easy to spot at a glance. When in doubt, choose PNG for the first conversion and keep JPG as a follow-up step once you have confirmed the image is fully opaque.
