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.
