Frequently asked questions
How many images can I compress at once?
There's no fixed limit. Hundreds of photos work on most computers; phones handle smaller batches.
Do all images use the same settings?
Yes. Change a setting and every image is re-processed to match.
Are file names kept?
Yes, the original names are kept with the new extension if you changed the format.
Are my images uploaded to a server?
No. Files are decoded, processed and re-encoded by your browser using the canvas API and Web Workers. Nothing is sent to any server, and there is no account or storage. Closing the tab discards everything.
