Convert PNG images to compact WebP.
PNG to WebP converts PNG images into the smaller WebP format, preserving transparency unlike JPG. Multiple images convert together and download as a single file or a zip archive. Files up to 100MB each.

Drop one or more PNG images into the box above, or click to browse for files.
Click Convert to WebP. Each image is re-encoded in your browser, keeping its transparency intact.
One image downloads as image-1.webp; two or more arrive together in images.zip.
Yes. Unlike JPG, WebP supports a full alpha channel, so transparent and semi-transparent areas in your PNG carry over unchanged. This conversion doesn't flatten anything to a solid background.
It varies by image, but WebP typically produces noticeably smaller files than PNG at similar visual quality, especially for photos and images with lots of color detail. Simple graphics with large flat-color areas may shrink less dramatically.
Every modern browser and most current image viewers and editors support WebP. If you need to share with an older app that doesn't recognize the format, convert back to PNG or JPG afterward.
No. The whole conversion runs on your device, so your PNGs stay with you unless you email the result or save it to My Files.
