PNG to WebP Converter

Shrink PNG files by 25–80% by converting to WebP. Transparency preserved.

Why convert PNG to WebP?

WebP typically produces 25–80% smaller files than PNG with no perceivable quality loss — switching from PNG to WebP is one of the highest-impact changes you can make to website performance. WebP supports both lossy and lossless modes plus transparency, so it's a drop-in replacement for PNG in most use cases. Browser support is now universal (Safari added it in 2020). The WebP encoding is processed in your browser via WebAssembly (libwebp) — no upload required.

About PNG

PNG is lossless and supports transparency — universal but large.
  • PNG was designed in 1996 as a free alternative to GIF
  • Lossless: every pixel of the source is preserved
  • WebP can match PNG losslessly while being 25–35% smaller

Frequently asked questions

How much smaller will the WebP be?
Lossy WebP at quality 80 is typically 70–85% smaller than the original PNG. Lossless WebP is typically 25–35% smaller. The exact ratio depends on the image content (graphics with flat colors compress better than photos).
