PNG compressor
Compress PNG images, free.
Drop a PNG, pick a quality target, and download a lighter file. The exact size saving is measured on your image, not estimated.
Common questions
- Is the PNG compressor really free?
- Yes. It runs without an account. Usage is rate-limited per IP to keep it fair; if you need higher volume, grab a Robin API key.
- Are my images uploaded or stored?
- Your file is processed on the fly and the result is handed straight back to your browser. Nothing is kept on our side afterwards.
- Will compressing change how the image looks?
- You choose a quality target. Higher quality keeps more detail at a larger size; lower quality squeezes harder. The tool shows the measured reduction so you can pick the balance you want.
