About PNG to WebP Converter
This is the conversion PNG to JPG cannot do. WebP supports a full alpha channel, so a logo, icon, sticker or product cutout keeps its transparent background while still shedding most of its file size. For a typical PNG with transparency, WebP often lands at a quarter of the weight or less — with none of the white-box problem you get from JPG.
Drop up to 15 PNG files (5MB each) and click Convert with WebP already selected. Preview each result over a coloured area of your page if transparency matters, then download individually or as a ZIP.
Most PNGs on the web are screenshots and graphics, and those are exactly where the savings are biggest. One caveat: WebP encoding here is lossy, so razor-thin single-pixel lines and very small text can soften slightly. Full-page UI screenshots destined to be read closely are the one case where staying on PNG is worth the bytes. For icons, illustrations, avatars and product images, WebP is almost always the right call — and unlike AVIF it encodes instantly and is supported everywhere.

Frequently Asked Questions
Does PNG to WebP conversion keep transparency?
Yes. WebP supports a full alpha channel just like PNG, so transparent backgrounds and soft edges are preserved exactly — you get PNG's transparency at a typically smaller file size.
Is WebP as sharp as PNG for logos and screenshots?
Yes, since this converts at maximum quality. WebP can losslessly represent the same sharp edges and flat colors that make PNG a good fit for graphics, usually in a smaller file.
Why isn't my WebP output much smaller than the PNG?
Images with large flat-color areas (simple icons, screenshots with lots of white space) already compress well as PNG, so the WebP savings are smaller than they are for photos.
Are my images uploaded to a server?
No. Conversion runs locally in your browser.
