Add a signature where it belongs
Open a PDF, enter the form-editing flow and add a signature item to the page. The signature can be positioned as part of the document instead of being sent as a separate image.

Complete simple form fields
Add a text form box for names, dates, short answers and other information that needs to sit on top of the existing PDF page.
Protect sensitive files
Create a password-protected PDF before sharing confidential paperwork. Locking is performed locally and produces an encrypted file for the recipient.
A clear three-step workflow
From source to
finished result.
ProScan PDF keeps the action, confirmation and saved file inside one focused workflow.
Open the PDF you need to finish
Choose the document from My Files and open the form-editing controls. The PDF remains visible while you decide whether to add text or a signature.
Place the form item
Choose Add Text Form Box or Add Signature, then position the item on the appropriate page. Review the result before saving the modified PDF.
Lock or share the finished copy
When the document is ready, use Lock to create a password-protected version or Share to send the file through the standard iOS share sheet.
Built for practical documents
Useful details.
Honest expectations.
A practical mobile signing flow
The goal is to complete everyday paperwork without printing, signing and scanning it again. Signatures and text fields are integrated into the PDF workflow you already use for viewing and organizing pages.
Password protection is a separate decision
Not every document needs encryption, so locking is available as an explicit action. You choose when a PDF should require a password rather than having security applied unexpectedly.
Clear completion feedback
Saving a modified or signed PDF produces a confirmation card so you know the operation finished. Cache invalidation ensures the library and preview are refreshed after a file changes.
