Frequently asked questions
How much can I compress an image?
Results depend on format and quality. JPG and WebP often shrink files by 40–80% at quality 70–85 with little visible change.
Are my images uploaded?
No. Compression runs locally in your browser; files are not sent to our servers.
Is this better than CloudConvert for images?
For quick single-image compression with no account, our tool is faster and keeps files on your device.
