How to convert a PDF into a fillable online form
Most organizations have a PDF that people print, fill in by hand, scan and email back — or download, type into, and attach. Turning it into an online form removes most of that friction. This guide covers the options, how to do the conversion well, and how to keep producing the PDF when you still need it.

First: fillable PDF, or online form?
“Make this PDF fillable” means two different things, and it is worth deciding which one you need before you start.
| Fillable PDF | Online form | |
|---|---|---|
| How people fill it | In a PDF reader, after downloading | In any browser, on any device |
| How it comes back | As a file, usually by email | As a response in a list |
| Validation | Limited; easy to skip fields | Required fields, formats and logic enforced |
| Conditional questions | Awkward | Show and hide questions based on answers |
| Phones | Often painful | Designed for it |
| Looks exactly like the original | Yes | No — but it can generate the original from each response |
A fillable PDF is the right answer when the document itself is the deliverable and the people filling it are comfortable with PDF software. If you are collecting information from many people, especially on their phones, and then acting on it, an online form is almost always the better tool.
Option 1: make a fillable PDF in Acrobat
Adobe Acrobat’s Prepare a form tool takes an existing document and detects the likely fields automatically, turning blank lines and boxes into fillable text fields that you can then move, adjust or add to. It is the quickest way to a fillable PDF, and the result looks exactly like the original.
What it does not change is the rest of the process: somebody still downloads the file, fills it in, saves it, and sends it back; somebody still opens each file and retypes the answers wherever they are needed.
Option 2: rebuild it by hand in a form builder
Any form builder — Google Forms, Microsoft Forms, Typeform, Jotform, Faldaro — can recreate the PDF’s questions as a web form. Done by hand, that means reading the PDF top to bottom and adding each question, choosing its type, and copying its options. For a one-page form, that is half an hour. For a twelve-page application with tables and conditional sections, it is a day, and the most common source of mistakes: a skipped question, a checkbox that should have been a single choice, an option list with a typo.
Option 3: convert it with AI
AI converters read the PDF — including a scan or a photo with no text layer — and draft the web form for you: fields, types, choices and sections. You still review it, but you start from a nearly finished form rather than a blank page.
Faldaro’s free PDF to online form converter works this way. Drop a PDF, or a PNG, JPEG or WebP photo of a paper form up to 5 MB, and it comes back as a preview of the web form. It needs no account, and the file is read once to draft the preview and not stored. If you sign up, the builder can generate the full form from the whole document — the same import is available inside the builder and in the AI assistant — ready to edit and publish.
How to convert a PDF well
Whichever route you take, the difference between a good conversion and a faithful copy is in these details:
- Fix the field types. A date should be a date picker, an email an email field, an amount a currency field. PDF forms express all of these as blank lines.
- Replace “if yes, go to section 4” with logic. Paper forms tell people what to skip. A web form can simply hide the questions that do not apply.
- Compute what the form asks people to add up. Totals, subtotals and percentages should be calculated, not typed.
- Make required fields required. This is where most of the time saved comes from: no more chasing missing answers.
- Split long forms into steps. One section per page reads far better on a phone than a single endless scroll.
- Drop the office-use-only box. Fields your team fills in afterwards belong in the review process, not in front of the person submitting.
- Ask for attachments properly. “Please enclose a copy of…” becomes a file upload field.
Getting a PDF back out
The usual objection to leaving the PDF behind is that someone downstream — an insurer, a regulator, a client’s legal team — still expects the PDF. You do not have to choose. A form tool that generates documents can produce the familiar PDF from every response.
In Faldaro, a document template can be a reproduction of your original PDF: the PDF’s own pages become the template, with lines, boxes, text and logos kept, and you bind form fields onto the places the answers belong. Converting the pages is plain computation and costs no AI credits. A workflow can then generate the filled document as a record moves — when it is accepted for review, say, or approved — attach it to the record, and — on plans that include e-signatures — send it out to be signed. The documents and payments page shows it end to end, and the document docs list the honest edges, such as gradients being left out.
What happens after the form
The reason the PDF was painful was never really the PDF. It was that every returned copy was a small project: open it, check it, retype it, forward it, remember it. Once responses arrive as structured records, the rest of the process can come with them — a review step, an approval from the right person, a notification to the submitter, a tracking link so they can see progress. That is where most of the time goes, and where most of the time is saved. The form approval workflow guide covers that part.
Quick recommendation
- The document is the product, and a few people fill it in: make a fillable PDF.
- Many people fill it in, often on phones, and you act on the answers: convert it to an online form.
- You need both: convert it, and generate the PDF from each response.
