Private PDF Reader & Editor · Android

Your PDFs,
for your eyes only.

PDFly finds the PDFs on your phone, locks them behind a PIN, and lets you read, highlight, sign and reorganise them — entirely offline. No account, no uploads, no tracking. Your documents never leave your device.

Inside the app

A document in flight —
and nowhere else.

Screenshots from the current build are on their way. Meanwhile, here’s the face of PDFly.

PDF ly
Key features

Everything you do with a PDF.
Nothing it shouldn’t.

Locked by default

A 4- or 6-digit PIN, optional fingerprint unlock, auto-lock in the background, and growing lock-outs after wrong attempts.

Fully offline

No account and no uploads. Your files, marks and signatures stay on your phone — PDFly itself never opens a connection.

Finds your PDFs

Pick folders, or scan the whole phone. Grid or list, seven sorts, filters, page-one thumbnails, and “Open with” from any app.

A calm reader

Picks up where you stopped. Search inside the PDF, bookmarks, night mode, go to page, and password-protected files.

Mark it up

Highlight along the text, draw, add shapes, arrows, text and stamps — in seven colours, solid or see-through. Undo and redo every step.

Signatures

Sign on the screen or import a picture of your signature. Keep up to five, behind the PIN, ready for any document.

Organise & merge

Reorder, turn and remove pages, merge PDFs together, or extract just the pages you need into a new file.

Originals untouched

Your marks live in PDFly. “Save as new PDF” writes a fresh copy with them in it — the original file is never changed.

Real redaction

Cover text with a solid box and it is genuinely removed from the saved copy — not just hidden under a shape.

How it works

Private from
the very first tap.

Set your PIN

Choose a 4- or 6-digit PIN and, if you like, turn on fingerprint unlock. PDFly can lock itself whenever you step away.

Bring in your PDFs

Pick the folders PDFly should look in, or let it scan the whole phone. Your library appears with thumbnails, ready to sort.

Read, mark & save

Read freely, try every editing tool, and save a marked-up copy, an extract, or a merged PDF when you’re ready.
