About this app

PDF Maker finds all your PDF files on your device and lists them in one place, together with your Word and text documents. Open a file in the PDF viewer to read it, then highlight, sign, merge or compress it, right on your phone.

Read PDFs comfortably
• Scroll up and down or side to side, page by page or continuously
• Zoom in, jump to any page, and pick up where you left off
• Night mode for dark pages, a brightness slider, keep screen on, and a dark theme for the whole app
• Search the text of a PDF, then highlight, underline or copy what you select
• Open password-protected files when you know the password

Annotate PDFs
• Highlight, underline and strike through text
• Draw with a pen, add text on the page, and erase marks
• Six colors, with undo and redo
• Your marks are saved to a copy, so the original file stays as it was

Sign PDFs
• Draw your signature with your finger and keep up to 5
• Tap the page to place a signature, then move or resize it
• Sign contracts, agreements and letters without printing them

PDF tools
• Merge PDF files: combine up to 50 into one, in the order you choose
• Split a PDF into two files at the page you pick, or organize its pages: reorder, rotate, delete and extract
• Compress PDF files to reduce their size. High compression needs Premium, or you can watch a short ad to use it once
• Lock a PDF with a password (AES-256), or unlock one when you know its password
• Save PDF pages as PNG images

Create PDFs
• Scan to PDF: point your camera at a page, and the document scanner finds the edges and crops it. Scan up to 50 pages into one PDF
• Images to PDF: turn up to 50 photos (JPG, PNG and more) into one PDF, one photo per page
• Word to PDF: convert a Word (.docx) or text (.txt) file on your phone, in A4 or Letter size

Word and text documents
• Read Word (.docx) and text (.txt) files in the built-in document reader, and share them

OCR: copy text from scans
• Recognize the text in a scanned PDF or a photo, then copy it or save a searchable copy
• Text recognition runs on your phone and reads Latin-alphabet text
• OCR needs Premium, or you can watch a short ad to use it once

Your files, organized
• Recent and Starred lists, sorting by name, date, size or type, and list or grid view
• One search box finds files, tools and words inside your PDFs
• Rename, share, print, and delete with undo
• Set PDF Maker as your default PDF app, so files from other apps open here

Private and offline
• Your documents stay on your phone. Reading, annotating, signing, merging, compressing, converting and OCR all run on the device, and your files are never uploaded
• No account and no sign-in
• Read, annotate, sign, merge, compress and convert offline
• The scanner and OCR come from Google Play services and may need a one-time download

Premium
PDF Maker is supported by ads. Premium is an optional subscription that removes ads and unlocks OCR and High compression. Everything else in this description works without Premium.

About file access
To find every document on your phone, PDF Maker asks for access to all files (Android 11 and later). It uses this access only to find, open and save your files. If you say no, you can still pick files one at a time with Browse files.
