Frequently asked questions

Does compression remove pages?

No. All pages are kept; only images inside the PDF are made smaller.

Is my PDF uploaded?

No. Compression runs in your browser on your own device, so private documents never leave it.

Does it work for scanned documents?

Yes – scans shrink the most, because they are mostly images. Scanning in greyscale instead of colour often halves the size again.

Is there a page or file limit?

There is no account limit. Very large files depend on your device’s memory; close other tabs if a big file is slow.
