Compress PNG — reduce file size, keep quality & transparency

Compress PNG images online for free while keeping the best possible quality. Our PNG compressor shrinks the file size of many PNG images at once and preserves transparency, so your graphics, logos, and screenshots load faster on the web without looking any different — no signup and no watermark.

Choose lossless compression to keep every pixel intact, or a lossy level for the smallest possible size. Either way, reducing PNG file size is quick and easy right in your browser. Files are encrypted in transit and deleted automatically after processing.

Compress PNG — frequently asked questions

How do I compress a PNG without losing transparency?+

Upload your PNG and compress it — our tool preserves the alpha channel, so transparent areas stay transparent in the smaller file.

Can PNG be compressed without losing quality?+

Yes. Choose lossless compression to reduce file size with no visible quality loss. For even smaller files, pick a lossy level.

Why are PNG files so large?+

PNG is a lossless format that stores a lot of detail, especially for photos. Compressing optimizes the encoding and can strip metadata to cut the size significantly.

Can I compress multiple PNGs at once?+

Yes. Upload up to 10 PNG images and compress them all in a single batch, then download them together as a ZIP.

Is it secure?+

Yes. Files are uploaded over encrypted HTTPS and deleted automatically after compression.
