Compress PDF - PDF Compressor

📄 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.
