DocuLockScan, import and edit documents
Updated 15 November 2026 · by the DocuLock team
In short. Tap the camera button to scan, or the import button to bring in a photo or PDF. DocuLock straightens the page, reads the text on your phone, suggests the type, holder and expiry date, and encrypts it before saving. Open any document to crop, turn, black out, sign or add text to a page, then save it or export it as a PDF.
How do I add a document?
- On Home or Documents, tap the round camera button at the bottom.
- Choose Scan a document for an ID, licence, lease or receipt. Apple's document camera finds the page edges and straightens each page.
- Or tap the import button and choose Document from Photos or Document from Files for a picture or a PDF. A picture that is clearly a document is cropped and straightened for you.
- Check the details DocuLock read from the page (type, holder, expiry date), pick a folder, and save.
Text recognition runs on your phone with Apple's on-device tools. Pictures are not sent to any service to be read. The words are kept, encrypted, so you can search for them later.
Can I save files from other apps?
Yes. In any app's share sheet, choose Save to DocuLock (in the actions list) or the DocuLock icon. Choose whether it is a document or a private photo, pick a folder, and it is sealed at once. You can also use Open in or Copy to DocuLock on a PDF in Files or Safari: it opens straight on the review screen.
How do I edit a page?
Open a document: its pages fill the screen, with a bar of Add, Sign, Export, Text and Tools. Every change is saved at once, and an Undo button stays for a few seconds.
| Tool | What it does |
|---|---|
| Crop | Drag the four corners. Pulling them onto a slanted page also straightens it. |
| Rotate | Turns the page a quarter. |
| Colour | Original, grey, or black and white for a clean photocopy look. |
| Brightness | Brightness and contrast sliders. |
| Hide | Drag over a number or address to black it out. The pixels underneath are removed from the saved page, not just covered. |
| Sign | Draw your signature with a finger and place it on the page. The signature is not stored anywhere else. |
| Text | Type a name, a date or initials, or tap one button for today's date or the holder's name, and place it like a signature. |
| Replace, Remove, Move | Swap a page for a new scan, remove it, or change the order. |
Can I edit a PDF?
Yes. To crop, black out or sign a PDF, DocuLock first turns its pages into pictures, after telling you. The words stay searchable and can still be copied, but you can no longer select text inside the PDF.
How do I get a PDF or a copy out?
Tap Export: Save as PDF puts every page in one file, Save a copy saves the pages as pictures, and Share a secure link makes a link that expires. A copy saved outside DocuLock is no longer encrypted, and the app says so before saving. To make one PDF from several documents, select them in Documents and choose PDF.

Questions
Does DocuLock read my documents on a server?
No. Text recognition runs on your iPhone with Apple’s on-device tools. Only the encrypted document is uploaded.
Can I black out a number before I share a document?
Yes. Use Tools, then Hide, and drag over the number. The blacked-out pixels are gone from the saved page.
Can I sign a lease or a form in DocuLock?
Yes. Open the document, tap Sign, draw your signature and place it. Use Text to add your name and the date. PDFs are turned into pictures first.
