Frequently asked questions

Can I compress a PDF to exactly 200 KB?

Is there a file size limit?

The tool runs on your device, so there is no upload limit from a server. Very large PDFs just take longer on your device.

Do my files get uploaded?

No. Compression happens in your browser — your file never leaves your device.
