Frequently asked questions

Are my files uploaded to a server?

No. Everything runs inside your browser using modern web technology. Your files never leave your device.

Is it really free?

Yes, completely free with no file limits and no sign-up required.

How much smaller will my PDF get?

It depends on the content. Scanned or image-heavy PDFs often shrink by 40–80%, while text-only PDFs shrink less.

Is there a file size limit?

Only your device's memory. Very large files simply take longer to process.

Will quality suffer?

With High Quality the difference is barely visible. Smallest Size downsamples images more aggressively.
