About Fill PDF forms
Why does my PDF have no fields to fill?
A flat PDF or scan can look like a form without containing interactive fields. This tool reads standard AcroForm fields. Use Add text to PDF for visible labels on a flat page; it does not create new form fields.
Does the completed PDF stay editable?
Yes. Filling saves an interactive copy with the entered values. Read-only fields cannot be changed, and XFA or signed forms are unsupported. Use Flatten PDF afterward if you need static field values.
Is this tool free, and do files get uploaded?
Yes. This tool runs locally in your browser without an account. PolyPDF does not receive your input files. Downloads are saved only when you choose to save them.
What files and limits does this tool support?
Choose 1 PDF files. The toolkit supports up to 30 MB per file, 80 MB total input, and 500 PDF pages. Image rendering is limited to 100 pages per operation and 16 megapixels per page. Password-protected files are unsupported; editing signed files is blocked.
Can an AI assistant use this tool?
Yes. The downloadable local MCP server exposes the same operation and validation rules. Compatible browser agents can use the selected files through WebMCP when their browser supports it. Read the setup and privacy details.
