PNG Compressor

Browser processing — files never leave your device

PNG files are often far larger than they need to be. Shrink them by re-encoding to WebP (keeps transparency) or JPG, locally in your browser.

  4. Review the savings and download.

About this tool

PNG compression is lossless, so a PNG cannot simply be 'saved at lower quality'. The practical way to shrink a large PNG is to re-encode it in a modern lossy format: WebP keeps transparency and usually cuts the size dramatically, while JPG is the right choice when maximum compatibility matters and the image has no transparency. This tool shows the exact size difference so you can pick the format that fits.

Frequently asked questions

Why can't the PNG stay a PNG and just get smaller?
PNG is lossless — its size is determined by the image content. Meaningful reductions require either shrinking the dimensions or re-encoding in a lossy format such as WebP or JPG.
Will I lose transparency?
Not if you choose WebP output — it fully supports transparency. JPG output fills transparent areas with a background color you choose.
Which output should I pick for screenshots?
WebP at 90% quality keeps text crisp and usually cuts screenshot size by well over half. Use JPG only if the destination cannot accept WebP.
