Why compress PNG images?

PNG is a lossless format, which means PNG files keep every pixel of detail — but that also makes them much larger than JPG or WebP. Logos, screenshots and graphics with transparent backgrounds are usually saved as PNG, and they can easily be several megabytes.

This tool compresses PNG files by converting them to WebP, a modern format that keeps transparency while producing dramatically smaller files. Your images are processed locally in your browser and never uploaded.

PNG compression FAQ

Why is my PNG file so large?

PNG is lossless, so it stores more data than lossy formats like JPG or WebP. Complex images with transparency are especially large.

Will converting PNG to WebP keep transparency?

Yes. WebP supports an alpha channel, so transparent backgrounds are preserved when you convert.

Is WebP smaller than PNG?

Usually, yes — a WebP version of a PNG is often 50–80% smaller with little visible difference.
