About this app

HanFlow PDF — a fast, ad-free PDF reader with a document scanner

Clean and quick, with only the features you need. No ads.
The interface follows your device language.

■ Document scanning
· Auto-capture — hold steady over a page and it captures by itself
· Book mode — one shot of an open book becomes two separate pages
· Shoot at an angle; the edges are found and the perspective corrected
· Five looks: document, black & white, photo and more
· Photos you already took go through the same process into one PDF

■ Free features
· Reading: pinch zoom, immersive mode, single-page or continuous scroll
· Page thumbnails, in-document search with highlighting
· Light / sepia / dark background — easier on the eyes
· Annotation: highlighter, pen, text notes, eraser (4 colours, 3 widths)
· Page bookmarks, favourites, sort by recent/name/size and grid view

■ Premium features (unlocked with an in-app subscription or a licence key)
· Text recognition (OCR) — pull text out of scans, or make a searchable PDF
· Save a new PDF with your annotations
· Merge PDFs — combine several files in the order you choose
· Page editing — rotate, delete, reorder, extract selected pages
· PDF ↔ images, text extraction, rotate all, page numbers, watermark, compress
· Share / export
※ One licence works with the HanFlow PDF desktop program as well

■ Private by design
· No ads
· Documents are never collected or transmitted, and nothing is shared with third parties for advertising or analytics
· Scans and PDFs are processed on your device — nothing is uploaded to a server
· "Open with HanFlow PDF" from Files, mail and messengers

Scan what is on paper, and read your PDFs the light way.
