PDF Hanko: Stamp & Sign PDFs

Stamp and sign a PDF, then send it right away. Scanned documents are ready to edit, too.

PDF Hanko brings Japanese-style digital stamps (hanko), handwritten signatures, document scanning and Japanese OCR together in one PDF app. No account needed. Everything is processed on your device, and your documents are never sent to a server.

CREATE A DIGITAL HANKO
• Type a name to make a mitome-in, round, square or date stamp
• Adjust the typeface (Koin-style, Mincho, Gothic, Kaisho-style), vertical or horizontal text, border weight, worn-ink effect and color (vermilion, red, black, navy)
• Photograph a real stamp or import an image (PNG / JPG / HEIC); the background is removed automatically for a clean, transparent impression (Pro)

STAMP AND SIGN PDFS
• Open a PDF and place a stamp or signature exactly where it belongs, then resize and move it freely
• Save your handwritten signature and reuse it. Create signatures from the camera or an image, too (Pro)
• Add text, dates, check marks, circles, crosses and freehand pen
• Highlight, underline, strikethrough, shapes, arrows and images (Pro)

SCAN PAPER INTO PDFS
• Documents are detected and straightened automatically. Color and black-and-white filters (Auto and Photo filters, brightness and contrast are Pro)
• Japanese OCR recognizes the text so you can copy and search it, and save a searchable PDF. OCR works offline

FILL FORMS AUTOMATICALLY (Pro)
PDF Hanko finds fields such as name, address, date and stamp box, and fills them from your personal or company profile. Your signature and stamp go in at the same time.

PDF TOOLS
• Add, rotate, duplicate, delete and reorder pages
• Images to PDF, PDF to images, remove metadata
• Merge, split and compress PDFs, add a watermark, and process several files at once (Pro)
• Encrypt PDFs with AES-256: a password to open, plus print, copy and edit permissions. Encryption can be removed too (Pro)

PRIVATE BY DESIGN
• No account, no ad or analytics SDKs
• App lock with fingerprint or face unlock
• Data on your device is stored encrypted, tied to your screen lock
• Temporary files are cleaned up automatically

FREE AND PRO
The free version lets you view, stamp, sign, fill in basic text, manage pages, save and share. It includes 1 custom stamp and 1 saved signature, scans of up to 3 pages at a time, and Japanese OCR 3 times a month.

PDF Hanko Pro removes every limit and unlocks the Pro features above. Choose monthly, yearly, or a one-time purchase. Prices vary by country and are shown in the app before you buy.

Try every Pro feature free for 7 days first. Start it from "Try free for 7 days" in the app. No Google Play purchase and no payment details needed; it never renews and nothing is charged. After 7 days the app goes back to the free version.

Monthly and yearly plans are auto-renewing subscriptions charged to your Google Play account. Manage or cancel anytime in Google Play > Subscriptions; Pro stays active until the end of the period you paid for.

WORTH KNOWING
• Stamps and signatures in PDF Hanko are placed on the PDF as images. They are not certificate-based digital signatures. If the other party requires a certified digital signature, please use a service that provides one.
• Only create stamps that belong to you or that you are authorized to use.

For phones and tablets with Android 8.0 or later. Available in Japanese, English and Vietnamese.
