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.
