Made for long documents

Textbooks run to hundreds of pages. QuickPDF is built to get you to the right one quickly and stay out of the way while you read.

Instant full-text search

Every page is indexed in the background and cached. Matches are highlighted on the page, with a results list and previous/next navigation.

Search your whole library

Look a term up across every recent document at once and jump straight to the page where it appears.

Highlights and notes

Long-press text to select it, then copy, highlight in four colors or add a note. Share bookmarks and notes as text.

Scanned books, searchable

Pages without a text layer can be recognized on the device: ML Kit for Latin-script languages, Tesseract for Russian.

Scroll or turn pages

Continuous scrolling fit to width or to the whole page, or page by page with two pages side by side on tablets.

Easy on the eyes

Sepia, night and night sepia page colors, pinch and double-tap zoom, a distraction-free full screen, and an option to keep the screen on.

Fast navigation

Drag the edge scroller through hundreds of pages, or jump by table of contents, bookmarks, notes, page number or thumbnails.

Password-protected PDFs

Encrypted documents open after you enter the password. Their text is never written to storage.

Private, and up to date

No accounts, analytics or ads, and documents never leave the device. The app tells you when a new version is out and installs it for you.

Search that forgives

Real documents are messy. QuickPDF finds what you meant, not only what you typed.

Accents

cafe→Café

Case and diacritics are ignored.

Cyrillic

елка→ёлка

ё and е match; й stays a letter of its own.

Line breaks

information→infor- mation

Words split by a hyphen at the end of a line are found.
