Why convert PNG to WebP?
A common step before putting an image on a website, since pages load faster with smaller files.
WebP files are usually a good deal smaller than PNG, so this is a common way to save space.
PNG keeps every pixel exactly, while WebP throws some detail away to save space. Use the quality slider to decide how much.
About the two formats
PNG: Keeps every detail sharp and supports transparent backgrounds. Works everywhere. The safe pick for logos, graphics and screenshots.
WebP: A newer format made for the web. Files are much smaller than PNG or JPG at the same quality, and it keeps transparent backgrounds.
The whole conversion happens in your browser. Your file is unpacked into raw pixels and saved again as WebP. Nothing is sent to any server.
Common questions
Is the PNG to WebP converter free?
Yes, properly free. No paid tier, no trial, no watermark on the result and nothing to sign up for. Put as many files through it as you like, as often as you like.
Are my files uploaded to a server?
No. The PNG to WebP converter runs inside your browser, on your own machine, so your files never go anywhere. Big ones are fine too, up to whatever your browser can hold.
Is WebP safe to use on a website now?
Yes. Every current browser has supported WebP for years, including Safari since 2020, so you no longer need a JPG or PNG fallback for ordinary visitors. The place to be careful is anything outside a browser, such as an older desktop program or a print service, which may still refuse the file.
Does converting PNG to WebP lose quality?
A little, because WebP saves space by throwing away detail the eye is least likely to miss, while PNG keeps every pixel exactly. At the default quality of 90 most people can't tell the two apart on a photo. Flat colour, sharp edges and text suffer the most, so lower the quality slider only while you're watching the preview.
Will the WebP file be smaller than the PNG?
Usually much smaller. WebP compresses far harder than PNG, and it's common to see a file drop to a fraction of what it was with no visible difference. How much you save depends on the picture, since photographs compress better than screenshots and line art.
