How it works

Why convert PNG to WebP?

Shrink PNGs, especially screenshots and logos, with WebP while keeping transparency. Use lossless for perfect edges and text, lossy for even smaller sizes with minor artifacts.

How WebP compares to PNG

WebP is generally more compact than PNG. The main differences are file size, quality characteristics, and transparency support.

Quality recommendations

For WebP output, start at the balanced preset and adjust to taste. A lower quality setting shrinks the file further; a higher one keeps more detail. Keep the original PNG file for archival edits.

Is conversion private?

WebP keeps your PNG transparency and compresses it in your browser. Nothing is uploaded or stored.

Batch convert PNG to WebP

Convert multiple PNG files to WebP together while keeping transparency. Free, private, batch ZIP, with no upload to any server.

Frequently asked questions

Does WebP preserve PNG transparency?

Yes. WebP supports alpha, so logos and icons keep transparent backgrounds while often halving file size compared to PNG.

Lossless or lossy for a screenshot?

Lossless keeps sharp text and edges perfect. Lossy cuts size further and is fine for photos inside screenshots if minor artifacts are acceptable.

How much smaller is WebP than PNG

WebP lossless is typically 25 to 30 percent smaller than PNG for graphics. For photographic PNGs the saving can be larger with lossy WebP. See PNG vs WebP for details.

Will converting to WEBP degrade quality?

Every WEBP re-encode discards a little detail. Keep your original file if you might re-edit it later.
