PNG to WebP: what to know

Converting PNGs to WebP mostly lightens the screenshots, illustrations and photos of a blog or online documentation. Transparency is kept, even with lossy compression: a cut-out logo keeps its soft edges on any background. For photos saved as PNG the saving is often dramatic; for a small icon in flat colours it is more modest.

The WebP is a file for publishing, not for working on: each new lossy save degrades the image a little, so keep your original PNGs for edits. Check how fine text and the lines of a diagram come out; if they look less crisp, raise the quality. Finally, some email programs still cannot read WebP, so PNG remains the safer choice for an email.

PNG vs WebP: what’s the difference?

PNGPortable Network Graphics

A lossless image format introduced in 1996. It keeps every pixel and supports transparency, which makes it ideal for screenshots, logos and illustrations. Photos are larger in PNG than in JPG.

WEBPWebP

A format created by Google in 2010 to make the web lighter. It compresses with or without loss, supports transparency and animation, and files are often 25–35% smaller than a JPG of the same quality.

PNG to WebP: frequently asked questions

Is a PNG’s transparency kept in WebP?

Yes. WebP has a full transparency channel, even with lossy compression: the transparent areas and soft edges of a logo or icon carry over as they are. That is a clear advantage over JPG, which fills the background with white.

PNG or WebP for the logo on my website?

WebP is usually lighter, but for a logo in flat colours PNG is already compact and keeps perfectly crisp edges. If you have the logo as an SVG, even better: it stays sharp at every size and often weighs just a few kilobytes. Compare both files before choosing.

Are my PNG files uploaded to the internet?

No. The file is read and converted by your browser, on your device. Nothing is sent to a server, and nothing is kept after you close the page.

Does converting PNG to WebP reduce quality?

WebP uses lossy compression, but at the default setting (90% quality) the difference is invisible to the naked eye. You can go up to 100% in the settings.

How many PNG files can I convert?

As many as you like, for free and without signing up. Add them all, then download the results one by one or in a single ZIP. The maximum size depends on your device and browser, with a few caps that protect its memory (for example 20,000 files per archive or 5 million filled cells per workbook: see the home page FAQ); a file over one of them is not converted, and a message says so.

Does it work on iPhone and Android?

Chrome, Edge and Firefox on a computer, and Chrome on Android, can create WebP files; a browser that cannot refuses the conversion with a message. Safari cannot create them yet, and on iPhone and iPad every browser runs on its engine, so use a computer for this conversion.
