Frequently asked questions

Can I compress a PDF to a specific file size?

Yes — use target mode to aim for about 500 KB, 1 MB, 2 MB, or 5 MB. The result is approximate: already-optimized PDFs or image-heavy scans may not reach the exact size.

Will compression reduce quality?

Results vary by content. Text-heavy files often shrink with little visible change; image-heavy scans may trade some detail for size. Check the download if quality is critical.

How much smaller will my PDF get?

It depends on the source. Already-optimized PDFs may shrink only a little; large scans often shrink more.

Is there a file size limit?

There is no fixed cloud quota. Very large files are limited by your device’s available memory.

Can I compress on a phone?

Yes, though large files usually finish faster on a desktop or laptop.

Do I need an account to compress?

No. Compression is free without registration.
