Frequently asked questions
How much can I shrink an image without visible quality loss?
For photos, 70–80% quality usually cuts the file size by half or more with no difference you can see. The result keeps the same dimensions and format.
Why does my PNG shrink less than my JPG?
PNG is lossless, so the quality slider doesn't change it and savings are smaller. If a file can't be made smaller, you get the original back and it shows 0% saved.
Are my files uploaded anywhere?
No. Image Compressor runs entirely in your browser. Your files are processed on your device and are never sent to a server.
Is there a file size limit?
No fixed limit. The only limit is your device's memory. Very large files work best in a desktop browser.
Is Image Compressor really free?
Yes. There's no account and no watermark. A short optional ad, or a 20-second wait, unlocks each download. That's how we keep it free.
Does it work offline?
Once the page has loaded, processing happens locally, so it keeps working even if your connection drops.
