Limits and behavior
Local processing. Maximum 10 MB per file, 25 MB total and 100 PDF pages. Encrypted PDFs require the separate known-password decryption tool. Digitally signed input may lose signature validity after any modification; preserve your original. Unsupported or malformed files produce an error. Cancellation stops active PDF renders and discards stale results; a synchronous library step finishes before the browser can handle cancellation.
Identify interactive fields inside a PDF
Read supported PDF form controls such as text fields and choices to understand how a fillable document is structured.
Can this tool edit the fields it lists?
No. Inspection reads the existing form definitions. Use the separate fill-form tool when you need to enter supported values.
