Frequently Asked Questions
Is this tool free?
Yes, it is 100% free with no sign-up. There are no limits on how many times you can use it.
How much can I shrink my image?
It depends on the image and the quality you choose. Photos saved as JPEG at 70–80% quality are typically 50–80% smaller with almost no visible difference.
Is my data uploaded to a server?
No. This tool runs entirely in your browser. Your files are never uploaded to a server and never leave your device.
Does compressing a PNG change its quality?
PNG is a lossless format, so the quality slider has no effect on PNG output. For the smallest file, choose JPEG or WebP output instead.
