Frequently asked questions

How does the Add Initials tool work?

Type and place initials anywhere on PDF pages. The operation runs from the tool workspace after you choose one PDF file.

Are files uploaded when I use Add Initials?

No. Processing is designed to run locally in your browser, so PrefillPDF does not receive or store the document used by this tool.

Will Add Initials overwrite my original file?

No. Your source remains unchanged. The tool creates a separate result for download.

What are the file limits for Add Initials?

You can use up to 1 file with a combined size of up to 100 MB per operation.

Can Add Initials open password-protected PDFs?

Encrypted PDFs may fail to open. Unlock the document first and then use the unlocked copy.

Does Add Initials reduce document quality?

The tool avoids intentional recompression when page content can be copied directly. Conversion tools render output at the configured quality.

Can Add Initials place initials on several pages?

Yes. Create and position separate initials marks anywhere they are required.
