How it works

Shrink a PNG into a WebP that's often 60-90% smaller, with transparency preserved. All in your browser.

This is the best conversion for putting PNGs on the web. WebP supports transparency like PNG does, but compresses far more efficiently — screenshots and graphics routinely drop 60-90% in size at quality 80-90 with no visible difference. Unlike converting to JPG, you don't lose the alpha channel, so logos and UI assets with transparent backgrounds keep their clean edges. Every modern browser (Chrome, Firefox, Safari 14+, Edge) displays WebP natively; the only reason to hesitate is if the image must open in older desktop software or be embedded in Office documents, where JPEG or PNG is safer. The quality slider controls the lossy encoding — 82 is a strong default. The conversion runs on a canvas in your browser, so the file never gets uploaded. Drop the PNG, convert, download the .webp.

Frequently asked questions

Does WebP keep my PNG's transparency?

Yes. WebP supports a full alpha channel, so transparent backgrounds and soft edges are preserved — the big advantage over converting to JPG.

How much smaller will the WebP be?

Typically 60-90% smaller for screenshots and graphics at quality 80-90. Photographic PNGs see the biggest drops.

Where does WebP not work?

Every modern browser supports it. Older desktop image viewers, some email clients, and Office document embedding can still be picky — use JPG or PNG there.

Is my PNG uploaded?

No. The conversion runs on a canvas in your browser — nothing is sent to a server.
