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 PRIVACY Your PDFs are processed on this device and are never sent anywhere. Usage statistics and error diagnostics are off by default. You can turn each one on separately in Settings, and turn them back off at any time. Available in English and Korean.
