Free to use. No credit card. No software to install.
Six steps from static PDF to fillable document. Steps 1–3 are free. AI auto-detection in step 2 is on paid plans — manual drawing always stays free.
Drag any PDF into the browser — a scanned paper form, a document exported from Word or Excel, a flat PDF downloaded from a website, or even a photograph of a printed form saved as PDF. Nothing is uploaded to any server at this stage; the file is rendered in your browser for preview.
On a paid plan, click "Detect Layout" and the engine scans the document for input lines, boxes, checkboxes, and table cells. It works on flat PDFs without AcroForm fields, on scans, and on complex multi-column forms where Adobe Prepare Form gives up. Each detected area becomes a fillable field.
Prefer to draw fields yourself? The free tier lets you click and drag rectangles over every area that needs to be filled. Name, address, date, signature line — just draw a box where each one goes. No AI credits used, no limits on the number of fields.
Every field is draggable and resizable. Reposition, shrink, or delete any field AI created. Add missed fields manually. Rename fields so paste-fill knows where each value belongs. What you see is exactly how the final fillable PDF will look.
Type values into each field, or paste a block of data and let AI map values to the right fields by name. Voice dictation in five languages is built in — click the mic, speak, and the transcription lands in the active field.
Click "Download Filled PDF" and get a standard PDF with your data embedded. The original layout and formatting are preserved. No watermarks, no "made with" footer. The result opens in any PDF viewer, including Adobe Reader.
There are several ways to convert a PDF into a fillable form. Here's how the common options stack up.
| Method | Difficulty | Cost | Works with scans | Flat PDF support | Auto field detection | Reusable templates | No install |
|---|---|---|---|---|---|---|---|
| JustFill | Easy | Free / from $9.99 | |||||
| Adobe Acrobat Pro (Prepare Form) | Medium | $19.99/mo (annual) | |||||
| Word developer form controls | Hard | Free (with MS Office) | |||||
| LibreOffice Draw | Hard | Free | |||||
| Manual (print, fill, scan) | Tedious | Free (time cost) |
Whatever the source, JustFill converts it to a fillable form without recreating the document from scratch.
Scanned or photographed forms are just images saved as PDF — they have no interactive fields. JustFill treats them as images and lets you draw fields on top or have AI detect the input areas automatically. No OCR setup required.
You saved a Word document as PDF but now you need recipients to fill it in. Upload the PDF to JustFill and convert it into a fillable form without going back to Word's developer tools — faster and works on any device.
Downloaded a PDF from a government website that turned out not to be interactive? Convert it once, save as a template, and reuse the layout every time you need to fill the same form.
Many older PDFs were never designed with interactive form fields. Rather than recreating the document in Word, add fields visually with JustFill and the original formatting is preserved exactly.
Long forms with tables, checkboxes, and signature areas across multiple pages are tedious to set up manually. AI field detection runs across the entire document and creates fields on every page.
If you have the open password for a protected PDF but it has no fillable fields, JustFill lets you add fields on top of the rendered image. The original file stays intact; the filled version is a new PDF.
Click one button and the engine reads your PDF like a human would — spotting input lines, checkboxes, signature areas, and table cells across every page. On a long form this turns 20 minutes of manual work into under a minute.
Every detected field is editable. If the AI misses a field or places one slightly off, drag, resize, or redraw it before filling.
For short forms or when you want precise control, draw each field by clicking and dragging a rectangle. This is the permanent free workflow — no AI credits used, unlimited fields, no watermarks on the download.
Once fields are in place, save the layout as a template. Future PDFs with the same structure pick up the layout automatically.
