Converted to PNG on your device - nothing is uploaded.
Ready · runs on your device
Nothing is uploaded. This tool runs entirely inside your browser tab. Your files and figures stay on your device - we never receive them, so we cannot read, store or lose them.
Why you would need this
WebP is technically the better format - smaller than PNG, supports transparency and animation, supported by every current browser. You are converting away from it for exactly one reason: something in your workflow cannot read it.
Common culprits:
- Adobe Photoshop before version 23.2 (2022) without a plugin
- Microsoft Office in older versions
- Many print and prepress workflows
- Corporate document management systems
- Some marketplace and CMS upload validators
- Older phones and desktop image viewers
You will also meet WebP when saving an image from a website - most modern sites now serve WebP, so “save image as” produces a file your image editor refuses.
Why PNG rather than JPG
PNG is the correct target because it is lossless and keeps transparency.
Converting WebP → JPG would discard the alpha channel and re-compress an image that has already been through lossy compression once, compounding the damage. Converting WebP → PNG copies the decoded pixels exactly, so nothing further is lost.
The cost is size. A 200 KB WebP commonly becomes an 800 KB to 2 MB PNG. That is expected and unavoidable: you are moving from an efficient modern codec to a format designed in 1996.
Lossy WebP is still lossy
If the source was lossy WebP - most web images are - its compression artefacts are already permanent. PNG preserves them faithfully. Conversion stops further degradation; it cannot reverse what has already happened.
Animated WebP
WebP can hold animation. PNG cannot. When you convert an animated WebP here you get its first frame only.
There is no good browser-side path for animated WebP → GIF, since neither GIF nor APNG can be written by a canvas. That needs desktop software such as ImageMagick or FFmpeg.
Converting back
If you converted to PNG only to satisfy a piece of software and now want the size back, run the result through the image compressor and target WebP or AVIF. You will not recover the original bytes exactly - a lossy round trip never does - but you will get back to a sensible size for publishing.
Common questions
Why will my software not open WebP?
WebP arrived in 2010 and browser support only became universal around 2020. Plenty of desktop software predates that or has never added it - older Photoshop versions, many print workflows, some CMS uploaders and a lot of corporate document systems. Converting to PNG is the reliable way around it.
Is transparency preserved?
Yes. Both WebP and PNG support a full alpha channel, so transparent areas survive the conversion exactly. This is why PNG is the right target rather than JPG.
Will the PNG be bigger?
Almost always, often several times. WebP compresses far more efficiently. You are trading size for compatibility, which is the entire point of this conversion - there is no other reason to do it.
What about animated WebP files?
Only the first frame is converted, because PNG cannot store animation. For an animated WebP you would need GIF or APNG, neither of which a browser canvas can write.
