Why convert PNG to WebP?

Keeping transparency while shedding most of the file size.

What is PNG?

PNG was created as a free replacement for GIF and compresses without throwing anything away. Lettering stays razor sharp, transparency works properly, and the same image survives being saved a hundred times. The trade is size: a photograph in PNG can be five times a JPG.

What is WebP?

WebP does everything at once: lossy like JPG, lossless like PNG, transparency, animation, and typically a quarter smaller than JPG at the same quality. Browsers love it. Photo editors, printers and older phones are far less enthusiastic, which is why so many WebP files end up being converted back.

What changes when you convert PNG to WebP?

Expect the file to shrink noticeably with no visible difference. The catch is elsewhere: some desktop editors, older phones and print shops still cannot open WebP, so keep the original if the image is going anywhere other than a website.

How long does it take?

Images finish almost instantly. Conversion runs on our server rather than in your browser, so the only real wait is the upload itself.

What happens to my files?

Your file is uploaded to our server because the conversion runs there. A cleanup task runs every hour and deletes anything older than an hour, so nothing you upload survives more than about two hours. We do not open your files, we do not keep copies, and no account is needed to use the converter.
