PDF Tool — Read & Edit PDFs

Read, annotate and rework PDFs on your phone — and keep the files on your phone.

READ AND ANNOTATE
• Pen, fountain pen, pencil, marker and brush, with an eraser
• Highlight, underline and strike through text
• Sticky notes, text boxes and shapes
• Sign with your finger and place the signature on the page
• Redact: black boxes on an exported copy — the text, the images and the form-field values under them are removed from the file, not just painted over. A page that can't be edited safely is turned into an image instead, and that page is no longer searchable. Your original document is never changed

REWORK
• Merge several PDFs into one, or split one into several
• Extract selected pages
• Reorder pages, reverse a selection or add a blank page
• Compress to make a file small enough to send
• Crop and resize pages
• Add a watermark or page numbers
• Images to PDF, and PDF to images
• Extract the text of a document

OCR ON YOUR DEVICE
Read the text out of scans and photos in Latin, Chinese, Japanese, Korean and Devanagari scripts. The recognition models run on the phone; scripts other than Latin download their model the first time you use them.

SCAN
Use the camera to scan a document straight into a PDF, with edge detection.

PROTECT
Set a password on a document, or remove one you know. A strength meter tells you when a password is too short to be worth setting. Lock the app itself behind your fingerprint or face.

ORGANISE
A library with folders, tags, search, sort and a trash you can restore from. Start a new blank note on plain, lined, grid, dotted, Cornell or music-staff paper.

QUICK ACCESS
A quick settings tile puts the scanner one tap away, from anywhere.

ABOUT PRIVACY, PRECISELY
Your documents stay on your device. The app has no account, no sign-in and no backend of its own, and it never uploads a file. Scanning and OCR use Google's ML Kit, which runs its models on the device but also ships Google's own telemetry component (a per-install identifier and performance data — never your document content) — so this app is not free of third-party code, and we would rather say so than claim otherwise. There are no ads.

LANGUAGES
Arabic, Chinese (Simplified and Traditional), English, French, German, Italian, Japanese, Korean, Portuguese (Brazil), Russian, Spanish and Turkish.

Requires Android 8.0 or later.
