Compress PDF

Make a big scanned PDF small enough to email. Runs on your device — nothing uploaded, text stays selectable.

Frequently asked

How do I compress a PDF for free?
Drop your PDF into Convertify, pick Recommended or Aggressive, tap Compress, then download. It runs entirely in your browser — no signup, no upload.
Does the PDF get uploaded to a server?
No. Compression happens on your device. Your file never leaves your phone or computer, so contracts and statements stay private.
Will the text still be selectable and searchable?
Yes. Only embedded images are downsampled. Text and vector content are never rewritten, so the PDF stays selectable, searchable, and sharp.
How much smaller will my PDF get?
Scanned and photo-heavy PDFs typically shrink 2-5x (e.g. a 2MB scan down to ~0.5-0.8MB). Text-only PDFs are already small, so there's little to gain.
Why won't my PDF compress much?
If it's mostly text it's already tiny. Compression mainly helps scanned documents and PDFs with large photos — that's where the bloat lives.
