PDF Reader Pro: Edit & Sign

PDF Reader Pro opens your documents quickly and gives you the tools to work on them, all on your device.

READ COMFORTABLY
Open any PDF from your phone or from another app. Choose vertical, horizontal, wrapped or single-page scrolling, and two-page spreads for wide documents. Four reading themes — Light, Sepia, Dark and true Black for AMOLED screens — with a night schedule that turns the app and the pages dark between two times you pick.

Arabic and Hebrew documents are laid out right to left automatically. Text reflow rearranges a page into one column so you can read it on a small screen without panning across. Read aloud speaks the document to you, following its language, with speed control and sentence-by-sentence navigation.

ANNOTATE AND SIGN
Highlight text in several colours, or underline and strike it through. Leave sticky notes anywhere on a page. Draw by hand with your finger — these become real ink annotations that other PDF apps can read. Sign a document by drawing, typing or choosing an image of your signature, and keep that signature for next time.

Everything you mark is saved per document and is still there when you come back. You can also write your highlights and signatures permanently into the file, or into a copy.

PDF TOOLS
Merge several PDFs into one, or split a PDF by page ranges, every N pages, or into single pages. Compress a PDF to make it smaller. Rotate, reorder, remove or extract pages. Crop the margins. Add a watermark, page numbers, or a header and footer of your own.

Lock a PDF with a password and set what others may do with it, or remove a password you know. Convert a PDF to Word, Excel, PowerPoint or plain text — the text and roughly how it was arranged carry over, though fonts and exact layout do not. Scanned PDFs are read with text recognition first. Turn photos into a PDF, or export PDF pages as images.

SCAN WITH THE CAMERA
Photograph pages with your camera and make a PDF from them, with edge detection and perspective correction.

FIND AND ORGANISE
Search inside your documents, not only by file name — the app reads your library once and then finds any word in any document, and opens it at the page. Accents are ignored both ways.

Label your files with tags of your own and filter the library by one. Move, copy, duplicate and rename files, or do it to several at once. Deleted documents go to a trash you can restore from. Mark favourites, browse by folder, and pick up where you left off from the recent list.

BACK UP WHAT YOU HAVE DONE
Save everything the app remembers — highlights, notes, bookmarks, tags, favourites and settings — into one file you can keep anywhere, and restore it later. Your PDFs are not copied into it; they stay where they are.

PRIVACY
Your documents are read and edited on your device. The app does not upload them anywhere. Passwords you ask it to remember are encrypted with the Android Keystore.

PDF Reader Pro is free and supported by ads.
