Frequently Asked Questions

What types of form fields are supported?

This tool supports standard PDF text fields. It detects text inputs, checkboxes, and dropdowns in your PDF form and lets you fill in text values.

What if my PDF has no form fields?

If the uploaded PDF does not contain any interactive form fields, the tool will display a message indicating that no fields were detected. Only PDFs with embedded form fields (created with tools like Adobe Acrobat) are supported.

Are the filled values permanently saved?

Yes. The form is flattened after filling, which means the values become part of the PDF content and the fields are no longer editable. This ensures the filled form looks the same on any device.

Is my PDF uploaded to a server?

No. All processing happens entirely in your browser. Your file never leaves your device, ensuring complete privacy.
