About PNG to WebP
PNG to WebP is the most valuable conversion on this site for anyone maintaining a website. PNG files are frequently the heaviest assets on a page, and WebP routinely cuts them by 60–90% while keeping the transparency that made PNG necessary in the first place.
WebP offers two encoding modes. Lossy behaves like JPEG but with an alpha channel, and gives the largest savings — ideal for photographs, screenshots and detailed illustrations. Lossless reproduces every pixel exactly like PNG does, but with a smarter compressor, so files still shrink by roughly 20–30% with zero visual change.
For logos, icons and UI graphics where absolute fidelity matters, use lossless. For anything photographic, lossy at 80% is almost always indistinguishable and vastly smaller.
How to convert PNG to WebP
Add your PNG files
Drag and drop up to 30 PNGs, or tap Select Images.
Choose lossy or lossless
Lossless keeps every pixel identical. Lossy gives much smaller files and lets you set a quality level.
Convert
Press Convert and compare the original and new sizes for each file.
Download
Save individually or download the whole batch at once.
Transparency is preserved
Unlike converting to JPEG, converting PNG to WebP keeps the alpha channel exactly as it was. Logos stay cut out, drop shadows stay soft, and partially transparent pixels keep their intermediate opacity.
This is what makes WebP such a strong replacement for PNG on the web: you get the one feature PNG was chosen for, without paying PNG's file size.
