Compress PDF

Frequently Asked Questions
Can I control the compression level?
Yes, you can choose the balance between file size and visual quality yourself — higher compression means a smaller file, lower compression means higher quality.
Does compression make the text unreadable?
No, the PDF's real text layer is preserved; compression primarily reduces image size, text stays sharp.
How much size reduction can I expect?
It depends on the document's content — image-heavy scanned PDFs shrink significantly, while already text-heavy PDFs may shrink less.
Can I compress multiple PDFs in bulk?
Yes, you can upload multiple PDF files at once, compress them in bulk, and download the result as a ZIP.
