How does the Inspect Form Fields tool work?
List interactive PDF form fields, types, values, and settings. The operation runs from the tool workspace after you choose one PDF file.
Are files uploaded when I use Inspect Form Fields?
No. Processing is designed to run locally in your browser, so PrefillPDF does not receive or store the document used by this tool.
Will Inspect Form Fields overwrite my original file?
No. Your source remains unchanged. The tool creates a separate result for download.
What are the file limits for Inspect Form Fields?
You can use up to 1 file with a combined size of up to 100 MB per operation.
Can Inspect Form Fields open password-protected PDFs?
Encrypted PDFs may fail to open. Unlock the document first and then use the unlocked copy.
Does Inspect Form Fields reduce document quality?
The tool avoids intentional recompression when page content can be copied directly. Conversion tools render output at the configured quality.
Can Inspect PDF Form Fields find fields in a scanned document?
It detects embedded interactive AcroForm controls. Printed boxes in a scan are not detected as fields.
