Why move PNG to WebP?

WebP was built to replace both PNG and JPG. For the kind of content PNG is normally used for — logos, icons, screenshots, illustrations with flat colour and transparency — WebP delivers the same crisp result in a noticeably smaller file, and it keeps the alpha channel intact. Google's benchmarks put lossless WebP at around 26% smaller than PNG, and if you're willing to use lossy WebP the savings on detailed images can be far greater.

The practical upside is faster pages. Images are the heaviest part of most websites, so swapping bulky PNGs for WebP is one of the simplest performance wins available.

Lossless or lossy?

This tool exports lossy WebP controlled by the quality slider. For graphics with sharp edges and text, keep quality high (90%+) so lines stay clean. For photographic PNGs, you can drop to 75–85% and still look great while saving a lot more. If you need pixel-perfect output and can't accept any change, PNG remains the safe choice.

Transparency is preserved

Unlike JPG, WebP keeps transparent backgrounds. That makes it a genuine drop-in replacement for transparent PNGs on the web.

How to convert

  1. Output is already set to WebP. Adjust the quality slider for the balance you want.
  2. Drop your PNG files above, or click to browse. Up to 200 at a time.
  3. Download each WebP, or grab them all as a ZIP.

If a tool won't accept WebP, JPG works everywhere (but drops transparency).
