Crossleaf: Search All PDFs

New in 1.2: Crossleaf is free for up to 3 documents. Add as many as you like with Crossleaf Unlimited, a single purchase. Everything stays on your device.

Crossleaf searches all your PDFs at once.

Add your manuals, textbooks and datasheets once, from Files or iCloud Drive, then type a phrase. Crossleaf shows every place it appears, in every document, organised by document, section and page. Tap a result and the page opens right at the match, highlighted. Go back and your results are still there.

SEARCH EVERYTHING AT ONCE • One search across all your documents • Results grouped as Document › Section › Page, from each PDF's own outline • Capital letters and accents don't matter • Works in many languages, including Chinese, Japanese, Korean, Arabic, Hebrew, Russian, Hindi and Thai • Search history for the phrases you look up again and again

SCANNED PAGES TOO • Pages without a text layer are read with on-device text recognition • Recognised text is searched like everything else, and matches are highlighted on the page • Nothing is uploaded to do it

MADE FOR iPAD, GREAT ON iPHONE • Three columns on iPad: documents, results and the page side by side • Full-screen reading with a single tap • A quick, one-handed search on iPhone

YOUR FILES STAY WHERE THEY ARE • Documents in iCloud Drive or Files are read in place; nothing is copied • Replace a file with a new revision and Crossleaf indexes it again • Give any document a short name to show in results

MARK UP WITH APPLE PENCIL • Draw and highlight right on the page • Your markup is saved into the PDF itself, so it shows up wherever you open it

BOOKMARKS AND REVISION REMINDERS • Bookmark any page, grouped by document • An optional weekly reminder to check for new revisions

PRIVATE BY DESIGN Crossleaf never connects to the internet and collects no data. No account, no tracking, no ads. Your documents never leave your device, which makes it safe for company manuals and other files you are not allowed to upload.

Free for up to 3 documents. Crossleaf Unlimited is a single purchase — no subscription.
