Convert PNG to WebP

Convert PNG to lossless WebP for ~ 25% smaller files with identical transparency. Lossless WebP beats PNG on size while keeping every pixel exact.

Lossless WebP produces files ~ 25% smaller than PNG for the same image — every pixel preserved exactly, transparency intact. For any graphic served from a modern website, this is essentially a free saving.

Keep PNG only when compatibility with legacy tools matters — email, downloadable brand kits, older CMSes. For images served on your own site, WebP wins.

Frequently asked questions

How do I convert PNG to WebP?
Drop your PNG file into the tool above. It's converted to WebP in the browser and ready to download. Multiple files can be converted at once.
Why convert PNG to WebP?
Lossless WebP produces files ~ 25% smaller than PNG for the same image — every pixel preserved exactly, transparency intact. For any graphic served from a modern website, this is essentially a free saving.
Is any quality lost when converting to WebP?
Converting between lossy formats (like JPG to WebP) involves one round of re-encoding, so there is theoretically some quality loss — but at the default quality setting it's visually indistinguishable. Converting to a lossless format (PNG) doesn't lose data from the source.
Does the WebP file work everywhere the PNG did?
Modern browsers, image editors, and platforms all support WebP. Older tools (2015-era software, some third-party services) may not — if you need maximum compatibility, JPEG or PNG remain the safest fallbacks.
Are my files uploaded anywhere?
No. Conversion runs entirely in your browser using the Canvas API. Files never touch our servers, which matters for pre-publication work, client assets, or anything sensitive.
