choose it from the menu.

Sign a PDF in a web browser
To sign a PDF on the web, the document must contain an empty signature field. When you sign a document in a
browser, only the incremental portion of the file is saved to your hard drive.

2 To retain a copy of the signed document, click the Save A Copy button in the File toolbar.
Sign in Preview Document mode
For best results, use the Preview Document feature when you sign documents. This feature analyzes the document
for content that may alter the document’s appearance, and then suppresses that content, allowing you to view and
sign the document in a static and secure state.
When you view a PDF in Preview Document mode, a document message bar lets you know if the PDF complies with
the PDF/SigQ Level A and Level B specification. Level A indicates that the document contains no dynamic content
that can alter its appearance. Level B indicates that the document contains dynamic content that can be suppressed
during signing. If the document doesn’t comply with Level A or B, you may want to refrain from signing the
document and contact the document author about the problem.
You can also use Preview Document mode outside of a signing workflow to check the integrity of a document.
Sign a PDF in Preview Document mode
1 Choose Edit > Preferences (Windows) or Acrobat > Preferences (Mac OS), and select Security on the left.
2 Select View Documents In Preview Document Mode When Signing, and click OK.
3 In the PDF, click the signature field, or click the Sign button in the Tasks toolbar and choose Sign Document or
Place Signature.
The document message bar appears with the compliance status and options.
4 (Optional) Click View Report in the document message bar (if available) and select each item in the list to show
details. When you’re done, close the PDF/SigQ Conformance dialog box.
5 If you’re satisfied with the compliance status of the document, click Sign Document in the document message bar,
and add your digital signature.
