FAQ

Common questions

Will compressing my PDF lose quality?

'Low' compression removes metadata with no visible quality change. 'High' compression also reduces image resolution, which may slightly affect scanned documents or image-heavy PDFs.

How much smaller will my PDF get?

PDFs with images typically compress 30–70%. Text-only PDFs compress 5–30%. We show the exact size reduction before you download.

Is there a file size limit?

We support PDFs up to 100MB. For larger files, try splitting your PDF first.

Can I compress multiple PDFs at once?

Currently one PDF at a time. Batch compression coming soon.
