Compress PDF - PDF Compressor

Reduce PDF size offline. Batch compress PDFs privately - no upload, no account.

📄 Compress PDF — Shrink File Size, 100% On Your Device

Need to reduce a PDF's file size for email, a portal upload limit, or just to
free up storage? Compress PDF shrinks your documents in seconds — without
ever uploading them anywhere.

Unlike most PDF compressor apps that quietly send your files to a server,
Compress PDF processes every document entirely on your phone. Nothing is
uploaded. No account, no sign-up, no cloud dependency — just a fast, private
pdf size reducer that works even with no internet connection.

🔒 100% OFFLINE, NOTHING EVER UPLOADED
Your documents are private, financial records, contracts, or personal files —
they should stay that way. This pdf compressor offline app never sends a
single byte of your PDF to any server. Compression happens locally using
native on-device processing, so sensitive files never leave your hands.

⚡ 5 COMPRESSION LEVELS — FROM ONE TAP TO FULL CONTROL
- High Quality — light compression, virtually no visible quality loss
- Medium — balanced size reduction
- Standard (Recommended) — smart default, no decisions needed
- Low Quality — maximum size reduction for strict upload limits
- Custom — full manual control over JPEG quality, image resolution/DPI,
color mode (grayscale/monochrome), metadata removal, thumbnail removal,
and font optimization, with a live estimated-size preview as you adjust

Most PDF compressor apps give you one button and a black box. This one gives
you a real dial when you want it — ideal for reducing scanned PDFs, shrinking
image-heavy reports, or hitting a strict file size cap for a form or portal.

📚 BATCH COMPRESS MULTIPLE PDFs AT ONCE
Select several PDFs and compress them all in one batch job. A dedicated
progress screen shows the real status of every file — waiting, compressing,
done, failed, or skipped — not a single vague progress bar. When it's done,
Share All or Export All bundles every compressed file into one zip, instead
of firing off separate share dialogs one by one.

🔐 HANDLES PASSWORD-PROTECTED PDFs
If a PDF is locked, the app detects it and asks for the password instead of
silently failing — so locked files don't break your workflow.

📖 BUILT-IN PDF VIEWER, HISTORY & EXPORT
- Preview any PDF before or after compressing — vertical or book-style
scrolling, pinch-to-zoom, rotate, jump-to-page, print, share, and a
night-reading mode
- Export or Save As to any folder on your device — not locked to app storage
- History tracks every compression with before/after size and % saved,
searchable by name, with one-tap re-share, re-export, or delete

🌍 BUILT FOR EVERYONE
20 languages including English, Spanish, French, Arabic, Hindi, Portuguese,
Russian, Urdu, Indonesian, German, Japanese, Turkish, Vietnamese, Korean,
Italian, Thai, Dutch, and Polish — with full right-to-left layout support.
Light, dark, and system themes, fully designed (not just inverted colors).
Set your default compression level once so you're never re-picking settings.

✅ WHO IT'S FOR
- Students and professionals emailing PDFs under a size limit
- Anyone uploading to a portal, application, or form with a strict cap
- People who just want to free up storage without losing document quality
- Power users who want manual control over DPI, quality, and color mode,
not just a single "compress" button

Compress PDF is free to use, with a Pro option that removes ads and lifts
the batch-size limit for unlimited files per batch — support ongoing
development and get early access to new features.
