🔒 Processed entirely on your device — your file is never uploaded.

Compression works by re-rendering pages as images, so it shrinks scanned or photo-heavy PDFs the most. Text-only PDFs may not get smaller.

Hit tight upload limits

Government portals, job applications and exam forms often demand a PDF under 100KB, 200KB or 500KB. SafePDF compresses your PDF locally so you can get under those limits without handing your documents to an upload site.

How to get smaller

Fewer, lower-resolution page images mean a smaller file. For heavily scanned documents you'll see the biggest drop. Everything runs on your device — your ID or form is never uploaded.
