Add Fillable Form Fields to a PDF Free — No Upload, No Account

Have a flat or scanned PDF with no interactive fields — a paper form someone scanned, or a document exported without any fields at all? PDFree lets you click directly on the page to drop in real, fillable text fields, right in your browser. Download a standard AcroForm PDF that anyone — including PDFree's own Fill tool, Acrobat, or any other PDF reader — can open and fill out digitally. Nothing is uploaded to any server.

Fields are written as real pdf-lib AcroForm text fields, verified to open correctly in independent PDF readers. Last verified: September 2026.

How to Add Form Fields to a PDF in 3 Steps

1
Open your PDF

Click Choose files or drag your PDF into the drop zone. PDFree checks whether the document already has interactive fields — if it does, you're pointed to the Fill tool instead, since this tool is only for documents that don't have any fields yet.

2
Click to place fields

Click anywhere on the page to drop a text field. Drag it to reposition, drag the corner handle to resize, and type a name directly into the field. Repeat for every blank on the page — and every page, using the page navigation above the preview.

3
Download the fillable PDF

Click Add Fields & Download. PDFree writes real AcroForm text fields into the document in your browser and downloads the result directly to your device — no waiting, no email, no account.

Who Needs to Add Form Fields to a PDF?

A scanned paper form

You scanned a printed form and now want people to fill it out digitally instead of printing, writing, and scanning again. Click-to-place lets you drop fields exactly where the printed blanks are.

A flat PDF exported without fields

Many documents — internal templates, simple applications, intake sheets — are exported as plain PDFs with no interactive layer at all. This tool adds one, without needing Acrobat or any desktop software.

Small businesses and freelancers

Turn a one-off contract, intake sheet, or order form into something a client can fill in on their own screen, without buying form-authoring software or a subscription.

Teachers, HR, and admin staff

Permission slips, onboarding checklists, and internal request forms often start life as a flat PDF. Add fields once and reuse the fillable version going forward.

Why Add Form Fields Here Instead of a Cloud Tool?

Most online tools that claim to make a PDF fillable require uploading your document to a remote server, where a copy sits until someone deletes it. PDFree works differently: the entire operation — rendering the page you click on, and writing the AcroForm fields into the output — runs inside your browser using pdf.js and pdf-lib, the same open-source libraries powering PDFree's other tools. Your PDF never leaves your device.

The fields this tool creates aren't a visual trick, either. Some tools "make a PDF fillable" by drawing a flat text box wherever you click and baking it into the page as a picture — it looks like a field but isn't one. PDFree writes an actual AcroForm text field into the PDF's structure, the same kind Acrobat creates, so the result opens correctly and stays genuinely interactive in any standards-compliant PDF reader — including PDFree's own Fill tool.
