Frequently asked questions
How does the Form Field Editor tool work?
View, edit, move, resize, remove, and add interactive PDF form fields. The operation runs from the tool workspace after you choose one PDF file.
Are files uploaded when I use Form Field Editor?
No. Processing is designed to run locally in your browser, so PrefillPDF does not receive or store the document used by this tool.
Will Form Field Editor overwrite my original file?
No. Your source remains unchanged. The tool creates a separate result for download.
What are the file limits for Form Field Editor?
You can use up to 1 file with a combined size of up to 100 MB per operation.
Can Form Field Editor open password-protected PDFs?
Encrypted PDFs may fail to open. Unlock the document first and then use the unlocked copy.
Does Form Field Editor reduce document quality?
The tool avoids intentional recompression when page content can be copied directly. Conversion tools render output at the configured quality.
Can Form Field Editor add fields to a scanned PDF?
Yes. Even when no fields exist, you can place new interactive controls over the scanned page.
