Frequently asked
Is Compress image really free?
Yes — free, forever, no account and no trial that bites. There is no server bill to recover because nothing is uploaded.
Are my files uploaded anywhere?
No. Your browser reads the file into memory and runs Compress image on your device. Open the Network tab and watch — you will see zero upload requests.
Is there a file-size or page limit?
No hard limit. The only ceiling is your browser memory, so very large files may be slow. We warn you before that becomes a problem.
Does it work offline?
Once the page has loaded, yes. You can turn off Wi-Fi and it still works — the strongest proof that nothing leaves your device.
