PDF Viewer

PDF Viewer is a fast, private PDF reader that runs entirely on your phone. No sign-in, no ads, nothing uploaded — your documents stay on your device and it works fully offline.

Open any PDF from the app or straight from your files, and read it exactly the way you like.

📖 READ IN HIGH QUALITY
• Crisp, high-resolution rendering with adjustable quality and zoom
• Paged (swipe) or continuous (scroll) reading modes
• Pinch and double-tap to zoom, with optional one-finger zoom
• Night mode (invert colors), page background colors, and app-only brightness
• Dark / light theme, keep screen on, orientation lock, and hide scroll bars

🔎 SEARCH — EVEN SCANNED PDFs
• Find any word across the whole document
• Built-in OCR reads scanned pages that have no text layer (Latin, Chinese, Japanese, Korean and Devanagari)
• Step through matches with clear highlights

✍️ SELECT & USE TEXT
• Long-press to select, then drag the handles with a live magnifier
• Copy, Share, Select all, or Web search

🧭 NAVIGATE FAST
• Recent files with thumbnails, file size and page count
• Go to page, a thumbnail grid, and bookmarks
• Resume where you left off; turn pages with the volume keys or by tapping the screen edges

🖼️ EXPORT & CONVERT
• Export pages as images — JPEG, PNG, HEIC, BMP or WEBP — with a quality control
• Images → PDF: pick photos, drag to reorder, and build a PDF (fit-to-image, fit-width or A4)
• Print, share the whole PDF, or share a single page

⚙️ MADE TO TUNE
• Render resolution and scale, max zoom, double-tap zoom and fit mode — all adjustable
• Performance presets control how many CPU cores render your pages
• A built-in user guide with clear tables for every option

🔒 PRIVATE BY DESIGN
Everything happens on your device. No account, no internet needed, no analytics, no ads.

Powered by Android's built-in PDF engine for reliable, high-quality rendering.
