Frequently Asked Questions
How much can I compress an image?
Typically 40–80% size reduction. A 2 MB photo can often be reduced to 400–800 KB with no visible quality loss.
Does compression affect image quality?
At high quality the result is nearly indistinguishable from the original. Only at very low quality will artefacts become visible.
What image formats are supported?
JPEG, PNG, and WebP are supported for input. You can also output to JPEG or WebP for maximum compression.
Is PNG compression lossless?
PNG is always lossless — the quality setting only applies to JPEG or WebP output, not PNG.
Is my image uploaded to a server?
No. Everything runs 100% in your browser — your files never leave your device.
Is the image compressor free?
Yes. Completely free with no sign-up, no watermarks, and unlimited use.
