PDF Master

PDF Master lets you change the words already in a PDF, not just write on top of them. Fix a typo in an invoice, update a date on a letter, or correct a name on a certificate, all on your phone. Your documents never leave your device.

EDIT THE TEXT ALREADY IN YOUR PDF
• Tap any line and type: the old words are really replaced
• New text uses the PDF's own font wherever it can, at the same size, colour and position
• Works with invoices, letters, resumes and certificates made on a computer
• Remove a line, or restore the original, with undo and redo

EDIT SCANNED AND IMAGE PDFS
• Reads the text in scanned pages so you can change it too
• Matches the scan's look: serif or sans-serif, bold, italic, ink and paper colour
• Try it free; saving scan edits is part of Premium

ADD TO ANY PDF
• Add text (including Hindi), freehand drawing, highlights, shapes and images
• Move, resize, undo and redo, then save as a new PDF, so your original is never overwritten
• Rotate, reorder and delete pages

READ
• Smooth, sharp page viewing with pinch-to-zoom
• Search text and jump between highlighted matches
• Dark pages for comfortable reading at night
• Opens password-protected PDFs

SCAN
• Photograph documents with automatic edge detection and straightening
• Clean-up filters: Enhanced, Grey and crisp Black & White
• Multi-page scans saved as one PDF

TOOLS
• Merge PDFs, split by pages or ranges, extract or delete pages, rotate
• Convert PDF pages to images, and images to PDF

PREMIUM (ONE-TIME PURCHASE, NO SUBSCRIPTION)
• No ads
• Save text edits in scanned and image PDFs (editing text in normal PDFs is free)
• Recognise text (OCR) in English and Hindi, so scans become searchable and copyable
• Compress PDFs by shrinking their images
• Protect PDFs with a password (AES-256) and remove protection with the owner password
• Sign documents with your own signature

PRIVATE BY DESIGN
Opening, editing, scanning and OCR all happen on your device. PDF Master has no account and no cloud upload. It's built on proven open-source engines (PDFium, PDFBox, OpenCV, Tesseract).

The free version is supported by ads and needs an internet connection; your documents are never uploaded. Premium also works offline.
