PDF Reader: Document Editor

PDF Reader is an all document reader and PDF editor for Android. Open PDF, Word, Excel, PowerPoint, TXT, CSV, RTF and EPUB files in one document viewer, then edit, sign, scan, merge, split and lock PDF files without switching apps. Every file on your phone is listed automatically, so reading a report, a contract or an ebook takes one tap.

📕 PDF READER & PDF VIEWER

Read PDF files with smooth scrolling, pinch to zoom and page-by-page or continuous view. Jump to any page number, search text inside the PDF and see every match highlighted. The reader resumes at the page you left, and night mode inverts colors for reading in the dark.

📂 ALL DOCUMENT READER & OFFICE VIEWER

The document reader opens Word files (DOC, DOCX), Excel spreadsheets (XLS, XLSX), PowerPoint slides (PPT, PPTX), plain text (TXT), CSV tables, RTF documents and EPUB ebooks. Files are grouped by type in the file viewer, with Recent and Favorite lists, a folder view and search by name, so the docx reader, xlsx viewer and PPT viewer you need is always one screen away.

✍️ PDF EDITOR & ANNOTATION

Highlight, underline or strike out text, add text boxes, and draw notes by hand directly on the page. Changes are saved into the PDF, so the annotated file can be shared or printed from any device.

🖊️ SIGN PDF

Draw your signature once, save it, and place it on any contract, form or invoice. Then export the signed PDF from your phone with no printer or scanner needed.

📷 SCAN TO PDF & IMAGE TO PDF

Use the camera scanner to capture paper documents and turn them into PDF files, or pick photos from the gallery and convert images to PDF in seconds. Reorder pages before saving and share the result as a single file.

🔗 MERGE, SPLIT & CREATE PDF

Merge several PDF files into one, split a long PDF into separate documents, or create a new PDF from scratch. The PDF tools run on the device and keep the original files untouched.

🔒 LOCK & UNLOCK PDF

Protect confidential PDF files with a password, and remove the password from a locked PDF when you know it.

🤖 AI SUMMARY

Select the pages of a long PDF and get a concise or detailed summary, then copy it to notes or a message. Useful for research papers, manuals and long reports.

📖 EBOOK READER

The built-in EPUB reader reflows text to your screen size and supports night mode, so novels and study books are as comfortable to read as PDF files.

🛡️ PRIVACY

No account or sign-in is required. Your documents stay on your phone: reading, editing, scanning, merging and locking all run locally. Only the pages you choose for AI Summary are sent for processing, and only when you tap Summarize.

📴 OFFLINE READING

The PDF reader and document viewer work without an internet connection. Open, annotate, sign and convert files on a plane, in the subway or anywhere without signal. Internet is needed only for AI Summary.

⚡ LIGHT & FAST

The app opens large PDF and Office files quickly and opens documents shared from email, messaging apps, the browser and the file manager.

IMPORTANT NOTE

PDF Reader needs permission to access files on your device so it can list and open your documents. Some PDF files use encryption or features that cannot be edited; these files can still be read, and a copy is created when edits are saved. AI Summary requires an internet connection and works on a limited number of pages per request. Scan quality depends on lighting and camera focus.
