Getting a lossless PNG from a WebP
This conversion exists to give you an editable master. PNG is lossless: it uses DEFLATE compression, so the pixels you save are the pixels you get back, no matter how many times the file is opened, edited and saved again. A WebP that has already been through a lossy encoder cannot be repaired, but wrapping it in PNG stops any further damage from piling up across an editing session.
Designers hit this constantly. An asset arrives as WebP from a website or a partner, and it has to go into Figma, Affinity Photo, GIMP or a Keynote deck for retouching or compositing. Transparency survives the trip, so a cutout logo can be dropped straight onto a new background. Developers doing visual regression work also prefer PNG, because byte level image diffs are meaningless when the format re-encodes on every single save.
There is no quality slider on this page and no background picker either, because neither would do anything useful. PNG has no lossy setting to expose, and its alpha channel accepts the WebP transparency as it is. The tool simply decodes the WebP, draws it on a canvas at its native pixel dimensions and writes a 24 bit PNG with alpha, so what you download is a faithful copy of what the WebP decoded to.
Expect the PNG to be considerably larger, usually two to four times the WebP and sometimes more for photographic content, because lossless encoding cannot approximate anything away. Flat graphics, screenshots and line art grow far less and occasionally shrink. Treat the PNG as a working file rather than something you publish, and export back to WebP or JPEG once the edits are finished.
Decoding happens through your own browser, so nothing about the image, including client work you are being paid to keep quiet about, touches a server. Up to twenty files convert per batch. Once you have the lossless master, the Image Color Extractor pulls the exact hex values out of it for a matching palette, and Image to Base64 turns a small finished asset into an inline data URI for CSS or an email template.
How the WebP to PNG Converter Works
- 01Drop the WebP files you want as editable masters into the upload area
- 02Each one is decoded at its native pixel dimensions, with no settings to choose
- 03Transparency is carried straight through into the PNG alpha channel
- 04Download the PNG files and open them in your editor of choice
Working with a lossless master
The value of a PNG here is stability rather than fidelity. It cannot recover detail a lossy WebP already discarded, but it does stop the loss from compounding. Every time a lossy file is opened, adjusted and saved again it goes through another encode, and after four or five rounds of that the artefacts become visible even to someone who was not looking for them. A PNG saved and resaved a hundred times is byte for byte identical to the first version. That is why retouching, compositing and any multi step edit should happen in a lossless container, with the export to WebP or JPEG saved for the very last step. It matters for automated work too. Visual regression suites compare screenshots pixel by pixel, and a format that re-encodes on every save produces differences that have nothing to do with the change being tested. Figma, Affinity Photo, GIMP, Keynote and Google Slides all import PNG without argument, which is still a longer list than the one for WebP.
When to Use WebP to PNG Conversion
Convert when the file is going to be edited rather than published. Retouching a downloaded asset, compositing a cutout onto a new background, dropping a graphic into a slide deck, or feeding an image into a tool that only reads PNG all qualify. It is also the fastest way to hand someone a file that will definitely open on their machine. Do not use PNG as your delivery format for the web, though, because the same image will typically be two to four times larger than the WebP it came from, which was the whole reason the WebP existed.
Common Use Cases
- Open a downloaded WebP asset in Figma, Affinity Photo or GIMP for retouching
- Keep a cutout with transparency intact while compositing it onto a new background
- Produce stable reference images for a visual regression test suite Image to Base64 Converter - Free Online Encoder
- Place a graphic into a Keynote or Google Slides deck that will not accept the WebP
- Build a working master before pulling an exact brand palette out of it Image Color Extractor - Get Palette Free
Expert Tips
- Do the format conversion first and all the editing afterwards, so only one lossy generation ever exists in the chain.
- Export back to WebP or JPEG when the edits are finished, because PNG is a working format rather than a delivery format for the web.
- If the PNG comes out smaller than the WebP, the image was flat graphics or line art and PNG was the better container all along.
Frequently Asked Questions
- No, and nothing can. If the source was encoded with lossy WebP, that detail is gone permanently. What PNG gives you is a guarantee that no further loss happens during editing, which is a different and still very useful thing.
- PNG is lossless, so there is no quality setting to expose. The encoder stores the exact pixel values it is handed. There is no background picker either, because PNG supports transparency and nothing needs to be flattened first.
- Usually two to four times the WebP for photographic content, and much less for screenshots, line art and flat graphics, which sometimes even shrink. PNG uses lossless DEFLATE compression, which is very effective on repeated pixel runs and poor on continuous tone detail.
- Only the first frame. This tool decodes the image through the browser canvas, which hands back a single still picture. For an animated source you need a dedicated frame extractor or a video tool instead.
