Scanfox turns your phone into a document scanner, a full PDF toolkit and a universal file viewer. Free, no watermark, no subscription, no sign-in — and every feature runs on your device.

Upload rejected for being too big? Compress any photo or PDF to the exact KB an SSC, UPSC, bank, passport or scholarship form demands — offline, no account.

★ COMPRESS TO AN EXACT SIZE
Squeeze any photo or PDF to the size a form demands — 50 KB, 100 KB, 200 KB, 500 KB and 1 MB presets, or type your own limit in KB, MB or GB. Built for government, exam and job-application uploads with strict size caps. When a target is impossible, Scanfox says so and gives you the smallest usable file instead of quietly ruining the document.

★ RESIZE FOR EXAM & PASSPORT FORMS
Resize photos and signatures to exact pixel dimensions with ready-made presets — the right file size and the right dimensions in one step.

★ NOTHING IS LOCKED BEHIND A PAYWALL
Every tool is free. No trial, no "pro" tier, no watermark on your files, no account to create, no daily limit. The only thing you can ever pay for is a single one-time purchase to remove ads.

★ SCAN ANYTHING TO PDF
Automatic edge detection, crop and Magic Color enhancement give you clean, sharp pages — up to 50 in one session, and you can append more to an existing file any time. Modes: Document, Book pages (splits a two-page spread), ID card (front and back on one page), QR & barcode, and Scan & translate. Scanfox warns you when a page comes out blurry, so you never file an unreadable scan.

★ OCR — EXTRACT TEXT IN MANY SCRIPTS
Pull editable text out of any scan or photo. Latin, Devanagari, Chinese, Japanese and Korean are detected automatically. Copy it, or save it as TXT, Word or PDF. "Make searchable" adds an invisible text layer to a scanned PDF so any reader can search and select it.

★ BUILT FOR BIG DOCUMENTS ON SMALL PHONES
Rendering, filtering and compression run across every core your phone has. A 514-page, 122 MB scanned book compressed down to 1.3 MB in about 100 seconds on a 4 GB entry-level phone.

★ TRANSLATE OFFLINE
Scan a page and translate it on the spot. Language packs download once, then work with no internet at all.

★ A COMPLETE PDF TOOLKIT
• Merge, split by page ranges, add pages to an existing file
• Reorder, rotate and delete pages by drag-and-drop
• Sign with a saved signature; annotate with pen, highlighter, text and eraser
• Watermarks and page numbers
• Password-protect and unlock PDFs
• Export pages as images, images to PDF, edit PDF info
• Crop, rotate, filter and print
Every tool asks whether to update the file or save a copy, so you never overwrite an original.

★ OPEN ALMOST ANY FILE
PDF, Word, Excel, PowerPoint, EPUB, RTF, TXT, CSV, HTML, Markdown, code and images — plus ZIP, 7z and RAR archives. Continuous scrolling, pinch zoom, night mode, a thumbnail strip, in-document search with highlighting, and text selection you can copy from.

★ ORGANISE YOUR LIBRARY
Folders, favourites, pin to top, instant search, multi-select, and a trash that holds deleted files for 30 days. Back up and restore your whole library as a ZIP. Hide documents in the Private Safe behind your fingerprint, lock the app, add a scan widget or Quick Settings tile, pin any document to your home screen. Temporary files from big jobs are cleaned up automatically.

★ YOUR FILES STAY ON YOUR PHONE
Scanfox has no servers and no account. Your documents, scans and extracted text are never uploaded anywhere — all processing happens on the device. Ads and the optional purchase go through Google's SDKs; everything else works with no connection at all.

★ 20 LANGUAGES
English, हिन्दी, বাংলা, मराठी, తెలుగు, தமிழ், ગુજરાતી, ಕನ್ನಡ, മലയാളം, ਪੰਜਾਬੀ, ଓଡ଼ିଆ, اردو, Español, 日本語, Français, Русский, العربية, Bahasa Indonesia, Italiano and Bahasa Melayu.
