Compress PDF: Shrink File

Your PDF never leaves your device. No upload, no account, no waiting.

Compress PDF makes PDF files smaller right on your phone. Pick a file, choose how much to shrink it, and save the result as a new file. Your original is never changed.

TWO WAYS TO SHRINK

Text-preserving compression re-compresses the images inside your PDF while keeping text selection, search, and links working. This is the default.

Strong compression turns every page into an image. It shrinks much more, but text selection, search, and links are lost. The app always asks first, so it never happens by surprise.

HIT AN EXACT SIZE

Need a file under 5 MB for an email attachment? Enter the size and the app tries progressively lower quality until the result fits. It measures the real file size each time — not an estimate — and keeps the best result it found.

HONEST RESULTS

• Real byte sizes before and after, with the actual reduction • If a file cannot be made smaller, the app says so instead of pretending • Cancel any time — the app stops and cleans up • Password-protected PDFs are not supported, and the app tells you why

OPEN FROM OTHER APPS

Open or share a PDF from Files or your email app and it goes straight into the app.
