About this app

PDF Master is the only PDF app you'll ever need. 📄 Scan, edit, sign, annotate, merge, split, compress and protect your documents — all from one fast, beautifully simple app. No account. No sign-up. Just open and go.

Whether you're a student marking up lecture notes, a professional signing contracts, or just trying to shrink a file small enough to email, PDF Master does it in seconds.

✍️ EDIT LIKE A PRO Add, replace and restyle text directly inside any PDF. Insert images, rotate and delete pages, and rearrange your document exactly how you want it — without flattening your file into a blurry image.

📷 SCAN ANYTHING Turn your phone into a pocket scanner. Capture documents, receipts and whiteboards with automatic edge detection and crisp, clean output. Save straight to PDF.

🖊️ SIGN & FILL FORMS Create your signature once, then drop it on any contract, invoice or agreement. Fill in interactive PDF forms and save them — no printing, no scanning.

🖍️ ANNOTATE EVERYTHING Highlight, underline, strikethrough, draw freehand, add sticky notes, shapes, arrows and stamps (Approved, Confidential, Draft and more). Mark up documents and save your notes right into the PDF.

🔀 MERGE & SPLIT Combine multiple PDFs into one, or pull out exactly the pages you need. Reorder, duplicate and delete pages with a simple drag.

🗜️ COMPRESS & CONVERT Shrink huge PDFs down to email-friendly sizes while keeping them sharp. Convert your photos into a single polished PDF in one tap.

🔒 PROTECT & UNLOCK Lock sensitive documents with a password, or remove passwords from files you own. Permanently redact confidential text so it can never be recovered.

🔍 OCR & EXPORT Extract text from scanned pages with smart text recognition, then export your PDF to editable Word or plain text.

📁 STAY ORGANIZED Browse all your files, jump back into recent documents, and star your favorites. Search, sort and switch between grid and list views instantly.
