Step by step
- 01
Try the built-in option first
Open the PDF in a supported Apple app, use Markup or Preview, add a signature, position it, and save a copy. This is usually enough for a quick finger-drawn signature.
- 02
Use a local app for a paper signature
If finger drawing looks unlike your normal signature, a signature-scanning app can photograph the ink, remove the paper background, and keep the result on the device for reuse.
- 03
Check what an online tool uploads
No account does not necessarily mean no upload. Before using a browser tool, read its privacy and retention information and avoid sending sensitive files when the handling is unclear.
- 04
Confirm the required signature type
An account-free image signature is not a certificate-backed digital signature. If the recipient asks for identity verification or a digital ID, use their required system.
PDF SIGN & SCAN
Your real signature, ready when the PDF arrives.
Scan it once. Place it carefully. Send the signed copy from your iPhone.
App StoreChoose the shortest safe route
- Use Apple’s built-in tool when a finger-drawn mark is acceptable.
- Use a device-local scanner when matching your paper signature matters.
- Keep the unsigned original before saving or sharing the signed copy.
Questions
Can I sign a PDF on iPhone without creating an account?
Yes. Apple’s built-in Markup or Preview tools can add a signature without a new service account.
Does no account mean the PDF stays private?
Not automatically. A web service can still receive an uploaded file. Check where processing occurs and how long files are retained.
Do account-free methods create digital signatures?
Usually not. Adding a drawn or scanned mark is different from certificate-backed digital signing.
