How to convert PNG to WebP
To convert PNG to WebP, drop your PNG into the converter above and download the WebP. Transparent areas carry straight over, so there is no background colour to pick first.
Drop your PNG into the box below, or a whole folder of them.
WebP is already selected, so there is nothing to set up.
Download the WebP, or take the whole batch back as one zip.
Your transparent background stays put
A PNG with a see-through background comes out of this converter still see-through. There is no colour to choose and nothing to clean up afterwards.
That is worth knowing, because it is the thing that usually goes wrong. Moving a logo off PNG often means landing on a format that cannot hold a transparent background at all, and what you get back is your logo sitting on a white or black box. Not here. Send a transparent PNG through and the WebP sits on your page the same way the PNG did.
The one control worth a glance is the quality slider. Left where it is, it suits almost everything. Nudge it up for a screenshot with small text, or artwork with thin lines, where you want every edge kept crisp.
Why people move PNG to WebP
Mostly for websites. A WebP holds the same picture in a much lighter file, so pages built from them load faster, which matters to visitors and to how your site is ranked.
If you look after a site, this is one of the easier wins available. Photographs, banners, product shots and background images are usually the heaviest things on a page, and moving them to WebP tends to take a noticeable weight off without anyone being able to see a difference.
The other common reason is simply room. A folder of PNGs takes up a lot of space, and if you are keeping years of screenshots or exports around, converting them frees up a surprising amount.
Questions people ask
Almost always, and usually by a lot. That is the main reason people make this change: the picture looks the same on screen and the file takes up much less room, which is what makes a web page feel quicker to load.
Yes. A logo or an icon with a see-through background comes out of this converter still see-through, with nothing to set and nothing to tidy up afterwards. That is the main reason to choose WebP over JPG for artwork like that.
Yes, at the setting the converter starts on. If you want to be careful with a particular image, the quality slider lets you ask for a sharper result, and it is worth nudging up for screenshots with small text or artwork with fine lines.
You get a still picture rather than the animation. If the movement is the point, keep your original file as well.
On the web, yes. Every current browser shows WebP files, so anything you put on a website is safe. Away from the web it is patchier: some older desktop programs and a few email apps still prefer a PNG, so it is worth keeping the original for those.
Yes. Drop in as many as you like and they queue up together, then come back as a single zip file rather than one download at a time.
