About PNG Compressor
PNG Compressor is here for getting image file size down: reduce PNG size, transparency preserved. It takes PNG and produces PNG. Nothing is sent anywhere: the browser reads the file, does the work and hands the result back.
The slow route to getting image file size down is installing something, making an account and uploading the file; this is the fast route.

PNG Compressor: questions
- Will I notice a quality difference?
- Re-encoding always costs something, so start at the lighter setting and only push further if the size is still wrong. The before-and-after figures on the page are the honest way to decide.
- Do I need to pay or register?
- No. Every tool on this site is free, with no account, no email and nothing to install.
- Which file types does PNG Compressor accept?
- The drop area takes PNG. Files are read from your device in the browser, so the format has to be one a browser can decode — that is why the accepted list on this page is finite and honest rather than "everything".
- What do I get back from PNG Compressor?
- The result is PNG, offered as a download the moment the work finishes. Multiple results come back together rather than as fifty separate save dialogs.
