This adds empty fields — it doesn't fill them in.A text box, checkbox or dropdown you drag onto the page becomes a real, interactive AcroForm field with nothing typed into it yet — the opposite of Fill PDF Form, which types answers into fields that already exist. Build the form here, then hand the result to Fill PDF Form (or any PDF reader) to actually fill it in. Your file is only ever handled in memory here, never written to our disk.

Turning a plain PDF — a template, a scanned layout, a blank page — into something people can actually type into: upload it, type a field name, pick Text field, Checkbox or Dropdown, and drag it onto the page. Repeat for every field, then download a real fillable PDF, ready for Fill PDF Form.
Text field creates a single-line box someone can type into. Checkbox creates a tickable box, off by default. Dropdown creates a list of options you set yourself (comma-separated) — the person filling in the form picks one. All three are real AcroForm fields: standard, interactive, and readable by any PDF viewer, not just ours.
These are opposite operations, and it matters which one you reach for. This tool adds new, empty fields to a PDF that may not have had any. Fill PDF Form does the opposite: it lists the fields a PDF already has and types answers into them. Building a template for other people to fill in? Start here. Have a form that already has fields and just need to answer it? Skip straight to Fill PDF Form.
Your PDF is processed entirely in memory on our own machine and handed back in the response — it is never written to our disk for this tool, and nothing is kept afterwards.
Built the fields and want to answer them right away? Fill PDF Form lists every one as a normal box, checkbox or dropdown. Need a signature on the page instead of a typed field? Sign PDF draws, uploads or types one directly onto the page. Want the finished, filled-in form locked so nobody can change the answers afterwards? Flatten PDF bakes them in.
Upload the PDF, type a field name, pick Text field, Checkbox or Dropdown, then drag a box onto the page. A dropdown also needs at least one option, comma-separated. Press Create and download the blank form.
Open the downloaded file in Fill PDF Form — every field you just created is listed there as a normal text box, checkbox or dropdown, ready to type into.
Text fields, checkboxes and dropdown lists — the common AcroForm field types that any PDF reader recognises as fillable.
No. This only creates text, checkbox and dropdown fields. To place a signature on a page, use Sign PDF instead — it draws, uploads or types one directly onto the page.
