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.
