About this app

Docvix is a complete document toolkit that runs entirely on your device. No sign-up, no uploads, no waiting on a server. Open a file, get your work done, move on.

A full PDF editor, plus a reader for Word, Excel, PowerPoint, CSV and text files. Everything happens offline. Your documents never leave your phone — which matters when the file is a contract, a payslip, an ID, or a client report.

━━━━━━━━━━━━━━━━━━━━
ORGANISE PAGES
━━━━━━━━━━━━━━━━━━━━
• Merge several PDFs into one, in any order you like
• Split a document by page or by range (1-3, 5, 8-10)
• Reorder pages by dragging them
• Rotate, delete, duplicate and extract pages

━━━━━━━━━━━━━━━━━━━━
SCAN WITH YOUR CAMERA
━━━━━━━━━━━━━━━━━━━━
• Multi-page scanner with automatic edge detection and cropping
• Filters for clean, readable scans, exported straight to PDF

━━━━━━━━━━━━━━━━━━━━
CONVERT
━━━━━━━━━━━━━━━━━━━━
• Photos to PDF, fitted to A4 or kept at original size
• PDF to JPG or PNG at the quality you choose

━━━━━━━━━━━━━━━━━━━━
COMPRESS
━━━━━━━━━━━━━━━━━━━━
• Three levels: light, balanced and strong
• See the estimated size before you commit
• Docvix never hands back a file bigger than the one you gave it

━━━━━━━━━━━━━━━━━━━━
OPEN MORE THAN PDFs
━━━━━━━━━━━━━━━━━━━━
• Word, Excel and PowerPoint documents (.docx, .xlsx, .pptx)
• CSV files open as a real table — frozen header, row numbers, numbers aligned right
• Text, Markdown and log files, with the encoding handled properly
• Open any of them straight from your file manager or another app

━━━━━━━━━━━━━━━━━━━━
FILL IN FORMS
━━━━━━━━━━━━━━━━━━━━
• Type into real PDF form fields — text boxes, tick boxes and drop-downs
• Your answers stay editable, so a typo is easy to correct
• Lock the answers in when the form is finished and ready to send

━━━━━━━━━━━━━━━━━━━━
ANNOTATE
━━━━━━━━━━━━━━━━━━━━
• Highlight, underline and strike through text
• Draw freehand, add boxes, circles and sticky notes
• Standard PDF annotations that open correctly in any other reader

━━━━━━━━━━━━━━━━━━━━
MAKE SCANS SEARCHABLE
━━━━━━━━━━━━━━━━━━━━
• On-device text recognition turns a scan into a searchable PDF
• Find and copy text in a photographed document
• Runs offline, like everything else

━━━━━━━━━━━━━━━━━━━━
EDIT AND SIGN
━━━━━━━━━━━━━━━━━━━━
• Draw your signature and place it on the page
• Add text anywhere — tap the page to position it
• Watermark every page, with a live preview
• Add page numbers, top or bottom

━━━━━━━━━━━━━━━━━━━━
PROTECT
━━━━━━━━━━━━━━━━━━━━
• Lock a PDF with AES-256 encryption, or unlock one you have the password for
• Password-protected documents work in every tool

━━━━━━━━━━━━━━━━━━━━
EXTRACT
━━━━━━━━━━━━━━━━━━━━
• Pull the text out of a PDF, copy it or save it as a text file
• Export page images
• View and edit metadata: title, author, subject, keywords

━━━━━━━━━━━━━━━━━━━━
READ AND MANAGE
━━━━━━━━━━━━━━━━━━━━
• Fast, smooth PDF reader with in-document search and night mode
• Readers for Word, Excel, PowerPoint, CSV and text files
• Recent files, favourites and search across both files and tools
• Rename, delete, print and share through the standard Android share sheet

━━━━━━━━━━━━━━━━━━━━
BUILT WITH CARE
━━━━━━━━━━━━━━━━━━━━
• Light, dark, system and Material You themes
• 10 languages: English, हिन्दी, Español, Français, Deutsch, Português, Italiano, 日本語, 한국어, 中文
• Big documents stay responsive — heavy work runs in the background

━━━━━━━━━━━━━━━━━━━━
PRIVACY FIRST
━━━━━━━━━━━━━━━━━━━━
Docvix has no servers and no account system. We cannot see your files, because they never reach us. The only network traffic in the app is advertising. Camera access is asked for only when you open the scanner.

━━━━━━━━━━━━━━━━━━━━
WHO IT IS FOR
━━━━━━━━━━━━━━━━━━━━
Students handing in assignments, professionals sending contracts, teachers preparing handouts, lawyers assembling bundles, freelancers invoicing clients — anyone who works with documents on a phone.

What’s new
