PDF Den — All-in-One PDF Tools

PDF Den puts every PDF tool you need in one app — and runs them on your device, not in the cloud.

Open it and work. No account, no sign-up, no subscription, and no watermark on the file you just made.

EDIT A PDF LIKE A DOCUMENT
Tap any line of text and type. PDF Den matches the original font, size and colour, so an edit looks like it was always there. Swap photos, add text boxes, or fill in a form the same way.

SCAN WITH YOUR CAMERA
Point at a page and PDF Den finds the edges, straightens the perspective and cleans the lighting. Scan a stack in one go and export a single sharp PDF. Make a scan searchable with on-device OCR.

CONVERT AND ORGANIZE
• PDF to Word, PowerPoint, JPG and ZIP
• Images, text and Office files to PDF
• Merge, split, extract and delete pages
• Rotate, crop, resize and reorder — on a visual page grid
• Compress large files without wrecking the text

SIGN, PROTECT AND ANNOTATE
Draw a signature once and reuse it. Add passwords, redact what should never be read, flatten a document so nothing can be changed, or highlight and comment as you read.

ASK AI ABOUT YOUR DOCUMENT
Get a summary, pull out the key points, or turn a long file into study flashcards — processed on your device.

READ COMFORTABLY
A fast viewer with search, bookmarks, sticky notes and a liquid reading mode that reflows a PDF to fit your screen.

BUILT AROUND PRIVACY
Your files are opened, edited and saved on your phone. They are never uploaded, and there is no account tying them to you. The app shows a banner ad on its browsing screens to stay free — ads never appear while you are editing, scanning or reading, and no ad code can see your documents.

Available in 14 languages, including full right-to-left support for Urdu and Arabic.
