How to make a fillable PDF form

A fillable PDF is an ordinary PDF with interactive fields on top: text boxes, checkboxes, dropdowns and signature areas. You take the layout you already have, mark where each answer goes, and save it. Anyone who opens the file can type into it instead of printing, writing by hand and scanning it back.

The practical benefit is legibility and reuse: no handwriting to decipher, and the same template works for the next hundred people who need to fill it in.

The steps

1. Start from the final layout — a PDF you already have, or a document exported to PDF. Fix the wording first; moving text later shifts every field you placed.
2. Open the file in a tool that supports form fields and switch to the form editing mode.
3. Add a field for every answer: single-line text for names, multi-line for comments, checkboxes for yes/no, dropdowns for a fixed list of options.
4. Name each field clearly — “client_email”, not “Text14”. Names end up in the exported data, and cryptic ones make the results unusable.
5. Mark the required fields, and set formats where they matter: dates, numbers, email addresses.
6. Add a signature field if the form has to be signed.
7. Test it as a recipient would: fill it in yourself, save, reopen and check that the values are still there.

Field types and when to use them

• Text — names, addresses, free comments. Set a character limit where space on the page is tight.
• Checkbox — independent yes/no answers, such as consent.
• Radio group — one choice out of several; unlike checkboxes, options exclude each other.
• Dropdown — the same, but for long lists that would not fit on the page.
• Date — prevents the classic 03/04 ambiguity between British and American formats.
• Signature — for approval; pair it with a date field.

Keep one idea per field. Splitting “full name” into first and last saves you from cleaning the data later, when you want to sort or import it.

Collecting the answers

Sending the file back and forth by email works for a handful of people and falls apart after that. If you expect volume, export the completed data instead of reading each PDF: most tools can produce a CSV of field values across many submissions, which you can open in a spreadsheet.

If the form is going to a wide audience and does not need to look like a paper document, an online form is a better fit — answers land in one place automatically. Use a fillable PDF when the layout itself matters: contracts, official applications, anything that will be printed or archived as-is.

Doing it in Ettex

Ettex PDF starts from a template or your own file: place the fields, fill them in, sign and download. The same document can be sent for signature without leaving the app, so a template you reuse monthly — an NDA, an offer letter — is prepared once and sent many times.
