PNG to WEBP
Convert PNG files to WEBP for a substantially smaller file that still keeps the transparent background. Because the conversion runs in your browser rather than on a server, your file is never uploaded, never stored and never seen by anyone else.
Drop your file to start.
The converter needs JavaScript, because the conversion itself runs on your own device rather than on a server. Enable JavaScript to load it.
Transparency is preserved
Unlike JPG, WEBP has a full alpha channel, so logos, icons and cut-out product shots keep their transparent backgrounds. This makes it the natural replacement for PNG on the web.
Typical savings
PNG stores photographic detail inefficiently, so converting a photo-like PNG to WEBP often cuts the file by 60–80%. Flat graphics with few colours save less, since PNG is already efficient for those.

Frequently asked questions
Does WEBP keep PNG transparency?
Yes. WEBP has a full alpha channel, so transparent areas are carried over intact.
How much smaller will the file be?
Photo-like PNGs commonly drop by 60–80%. Flat graphics and icons save less because PNG already handles them well.
Is the conversion lossless?
The conversion here is lossy and controlled by the quality slider. That is what produces the size saving; set the slider high for a near-identical result.
Can I convert a whole folder?
Drop as many files as you like into the queue and convert them all in one press.
