Convert PNG to WEBP
Turn a PNG image into WEBP right in your browser. WEBP was built for the web and usually produces much lighter files than PNG while keeping the quality — ideal for making a site fast or saving space. Transparency is preserved, and the conversion happens on your device, without sending anything to servers.

How to convert PNG to WEBP in 3 steps
Add the PNG
Drag the image onto the upload area or click to pick it. The file is read only in your device's memory.
Convert
Click process. The image is re-exported as WEBP, keeping transparency when present.
Download the WEBP
Download the converted image. No copy is kept anywhere.
The gain with no trade-off
PNG is universal and lossless, but heavy. On a website, large images make pages slow and use more bandwidth. WEBP was made precisely to solve that: in most cases it produces a much smaller file than PNG, with equivalent visual quality.
For anyone building sites, stores or blogs, that translates into faster loading, a better experience for the visitor and even an SEO gain — lighter pages tend to rank better.
Transparency preserved
Unlike JPG, WEBP supports transparency — just like PNG. In this conversion, transparent areas of your PNG stay transparent in the WEBP.
That lets you swap heavy PNGs for light WEBPs without giving up logos, icons and cutouts that need a transparent background.
Here you don’t have to choose between weight and quality
This is the most rewarding conversion in the set. WEBP has a lossless mode that preserves every pixel exactly as in the PNG — and still produces a file around 26% smaller on average.
Transparency is kept in full. For logos, icons, screenshots and charts headed for the web, you end up with the same image taking less space.
What to check before publishing
Browser compatibility is total today, but outside the browser there is still friction: some desktop programs, older email clients and internal systems won’t open WEBP. If the image will travel by email or go into a document, PNG remains the safe choice.
For use on a website, WEBP is the better option in nearly every case. The conversion runs entirely in the browser, without sending the file anywhere.
It is worth running the test on your own file: on very simple images with few colours, the PNG is sometimes already so optimised that the difference stays small.
Use cases
- Make a website's images lighter and faster
- Save bandwidth and storage space
- Replace heavy PNGs while keeping transparency
- Improve page load speed (and SEO)
- Prepare optimized images for a store or blog
Frequently asked questions
Is the WEBP smaller than the PNG?
In most cases, yes — with equivalent visual quality. It's the main reason to use WEBP on the web.
Is transparency preserved?
Yes. WEBP supports transparency, so transparent areas of the PNG stay transparent.
Do all browsers open WEBP?
All modern browsers support WEBP. Very old programs may not recognize it — in that case, prefer PNG or JPG.
Does quality drop a lot?
The conversion uses high quality (92%); for most uses the difference is imperceptible, with a much lighter file.
