Convert WebP to PNG

Save WebP images as PNG files that every editor and upload form accepts, with transparency kept.

Shape

Changing a setting converts every image again. Resizing keeps the proportions, and smaller images are never enlarged.

Why convert WebP to PNG?

Many images you save from websites arrive as WebP, and some software still won't open them: older versions of image editors, office suites, print shops and plenty of upload forms. PNG opens everywhere.

PNG is lossless, so converting adds no new compression damage, and transparent areas stay transparent. The trade-off is size: a photograph saved as PNG can be many times larger than the WebP it came from. If you don't need transparency, converting to JPG gives a much smaller file.

This is one photograph, not a general rule: flat graphics, text and transparency compress differently. The converter on this page uses your browser's encoder, so its files will be close to these but not identical.

Questions

Does converting to PNG improve the quality?
No. PNG keeps exactly the pixels the WebP decoded to, so it loses nothing more, but it can't restore detail the WebP compression already removed.
Why is the PNG so much bigger?
PNG stores every pixel without lossy compression. That's ideal for graphics and text, but photographs rarely compress well that way. Use WebP to JPG if file size matters more than transparency.
Can I convert animated WebP?
This converter saves the first frame only. Animated images aren't supported.
Are my images uploaded anywhere?
No. The file is decoded and re-encoded by your browser on your device, and the converted copy is handed straight back to you. Nothing is sent to Img9 or anyone else, so the page also works offline once it has loaded.
Is there a file size or count limit?
There is no account and no daily limit. The practical limit is your device's memory: very large images, roughly 50 megapixels and up, can fail in some browsers, and phones hit that sooner. Set a maximum width to make big photos smaller as they convert.
