How to convert PNG to WebP
One or a hundred, transparent ones included. Nothing is uploaded at any point.
Photograph: leave lossless off and use the quality slider. Logo, icon or screenshot: turn lossless on, which usually still beats the PNG on size.
The download is a .webp ready to serve. Keep the PNG if anything in your workflow still refuses the format.
Lossless or lossy, converting a PNG?
This is the only real decision on the page, and it turns on what the image is rather than how much you care about quality.
If it is flat artwork, a logo, an icon, a screenshot, a chart, anything with hard edges and areas of solid colour, turn lossless on. WebP has a lossless mode that is simply a better compressor than PNG for that kind of image, typically twenty to thirty per cent smaller with every pixel identical. There is nothing to weigh up: you keep exactly what you had and the file is smaller.
If it is a photograph, leave lossless off. WebP lossless on a photograph will often come out larger than the PNG, because neither format is designed for that and one of them at least tries. Lossy WebP at quality 82 will be a fraction of the size and visually indistinguishable.
Either way the alpha channel survives, which is the reason to pick WebP over JPG here. A transparent PNG becomes a transparent WebP.
PNG to WebP FAQ
Will transparency survive?
Yes, in both lossy and lossless mode. WebP has a full alpha channel, so a transparent PNG becomes a transparent WebP with nothing flattened. This is the main advantage over converting to JPG, which would put white behind it permanently.
Does every browser support WebP?
Every browser released in the last several years does, Safari included. The gap is outside the browser: plenty of desktop software and upload forms still refuse it, which is why converting the other way is such a common search.
Should I use lossless?
For logos, icons, screenshots and flat artwork, yes: it keeps every pixel and still usually beats the PNG on size. For photographs, no: lossless WebP on a photo often comes out larger than the PNG, while lossy at 82 is a fraction of the size and looks the same.
Is this better than just compressing the PNG?
Usually, if the destination reads WebP. The PNG compressor is limited to what the PNG format can do; WebP is a better compressor for the same picture. If anything in your workflow still refuses WebP, compressing the PNG is the safer answer.
Are my PNG files uploaded to convert them?
No. The PNG is decoded and the WebP is written by your own browser, in this tab. There is no upload endpoint in the site for a file to go to, which you can check in your network tools: convert something and watch that no request carries it. Disconnect from the network after the page loads and it still works.
Does this remove EXIF, GPS and AI metadata?
Yes, every time, and there is no way to turn it off. The image is decoded to pixels and encoded again from those pixels alone, so EXIF and GPS, the XMP packet, embedded colour profiles, and any Content Credentials or AI-generation tags the file arrived with do not survive. There is no switch for this, because there is no way to keep them. What no compressor can remove is a watermark written into the pixels themselves, such as the invisible marks some image generators add: those survive re-encoding here and everywhere else.
