What you can do with DocToolkit
Scan documents: use the camera as a pocket PDF scanner for notes, bills, ID copies, books and receipts. Auto-crop, choose A4, 1:1, 16:9 or 4:3 frames and pick high, medium or low quality.
Edit and organize PDFs: merge several PDF files into one, split a large PDF, compress it to share faster, crop margins, reorder or rotate pages, then annotate and sign.
Extract text: turn scanned pages and photos into editable text with built-in OCR, copy it, or save it as a TXT file.
Private by design: no account, no ads, no analytics. Lock PDFs with AES-256 and protect the app with fingerprint or face unlock.
DocToolkit is coming soon to Google Play.
Word, Excel and PowerPoint files open as text and table previews and are not edited in the app. OCR supports English and other Latin-script languages.
