Quick answer
For a downloadable fillable PDF, compare Acrobat Proās field-authoring tools, Sejdaās existing-file or blank-page workflow, and PlatoFormsā AI-assisted PDF Document Creator. For online completion, PlatoForms offers original-layout or responsive PDF forms; DocHub and pdfFiller provide document-sharing and signing routes, while Jotform Smart PDF Forms maps browser responses into an existing PDF. Choose by the starting document, filling experience, and output you needānot simply how often you use the tool.
Which Tool Should You Use to Create a Fillable PDF?
To make a PDF fillable, first decide whether people should complete a downloaded file or a browser form. For a file, compare field-authoring controls and the saved result. For an online PDF form builder, compare the question layout and the completed PDF it produces. The shortlist covers both, and each entry identifies its stronger use case.
If you have already chosen the PlatoForms route, the step-by-step guide to creating a fillable PDF form covers setup. Use this article to choose a tool; use the guide to build the form.
Fillable PDF Tools at a Glance
Acrobat and Sejda suit work on downloadable PDF files. PlatoForms also offers downloadable fillable PDFs through Document Creator, alongside hosted forms for collecting responses. The table separates how each tool creates and delivers the form.
| Tool | Best for | How people complete the form |
|---|---|---|
| Adobe Acrobat Pro | Detailed PDF field authoring and source-document editing | Downloadable PDF; Acrobat Web Forms provide online completion |
| Sejda | Field placement on existing PDFs or blank pages | Downloadable PDF or a fill-and-sign link backed by a publicly shared Google Drive source PDF |
| DocHub | Reusable templates and signature requests | Fields assigned to recipients; public Fill a Copy links on Pro or Site License |
| pdfFiller | PDF editing and online document collection | Fillable documents; Premium adds web form collection |

| Jotform Smart PDF Forms | Online questions paired with an existing PDF | Browser responses populate the original PDF |
PlatoForms lists online signing on paid plans. Signature certificates are optional and require separate configuration. Multi-participant processes also use the relevant Workflow certificate settings; adding a signature field alone does not generate a certificate.
1. Adobe Acrobat Pro: Detailed PDF Form Authoring
Acrobat Pro is an option when you need to control a downloadable PDF’s fields and continue editing the underlying document. Adobe’s form preparation and distribution guide covers the file-based workflow; its online Web Forms offer a separate collection route.
Price: Adobe lists its individual annual prepaid plan at $239.88 per user, equivalent to $19.99/month; a month-to-month subscription is $29.99 per user.
2. Sejda: Add Fields to Existing PDFs or Blank Pages
Sejda PDF Forms lets you place form fields on an existing document or start from a blank page. Its free limits and short paid passes suit limited projects, while subscriptions support ongoing use. The route adds fields directly to a file you supply or create.
Price: Sejda is free within service limits; its paid web plans include a $5 week pass and a $7.50 monthly subscription per user.
3. DocHub: Reusable Documents and Signing
DocHub combines fillable field creation with templates and signature requests. It supports preparing a document once and using separate copies with new recipients.
Price: DocHub offers a free tier; use its regional pricing selector for Basic or Pro. Basic includes advanced fields and unlimited templates, while public documents and unlimited signature requests require Pro or Site License.
4. pdfFiller: Edit, Then Collect Documents
pdfFiller fits a team that needs to change the source PDF as well as receive completed copies. LinkToFill gives recipients a shared entry point while keeping their completed responses separate.
Price: pdfFiller Basic starts at $8/month on annual billing; Premium, the relevant plan for online collection, is $15/month annually or $40 month-to-month.
Plan fit: Include Premium when comparing online collection and signing. For a downloadable blank form, check the field-creation and export options you need. The pdfFiller comparison covers these routes in more detail.
5. PlatoForms: Online PDF Forms and Downloadable Fillable Documents
PlatoForms offers two starting points: convert an existing PDF into an online form, or design a new document for downloadable fillable PDF export. For online completion, respondents enter their answers through a shared link and PlatoForms generates the completed PDF. For file-based completion, recipients download the fillable document and use a compatible PDF viewer.
Choose how people fill it out. A PDF Fillable Form keeps your PDF as the background and adds interactive fields. A Web PDF Form presents the questions in a responsive layout for phones and maps the answers back to the original PDF. You can make the filling experience easier without redesigning the document your team needs to receive.
Spend less time setting up fields. AI field detection identifies fields in an uploaded PDF for you to review and adjust. Web forms can use conditional logic to show relevant questions and validation to check answers before submission. This helps with forms that need more guidance than an editable box on a page.
Reuse answers and automate the next step. For several documents, Master Forms let one set of answers populate multiple linked PDFs. For example, a new client can enter their contact details once for an application and consent form. Workflows let another participant complete their step. You can configure PDF email attachments and cloud-drive delivery so staff receive the finished documents without manually transferring each answer.
Create a new fillable PDF when you do not have one. PDF Document Creator starts from a blank canvas, a preset, or an AI prompt. Add and arrange input components, then export a downloadable fillable PDF or convert the document into an online form. The downloadable file is useful when recipients need to complete a PDF outside the online form; test complex layouts in the intended PDF viewer.
For a new online form, PlatoForms also offers application templates and registration templates. Customize these web-form layouts when people will respond in a browser; use the Document Creator route above for a downloadable fillable PDF.
Best fit: You want to convert an existing PDF into an online form or create a new downloadable fillable document with AI-assisted design. A single form can use either route. For online collection, add signatures, Workflow, or cloud delivery when needed. These online features are separate from the fields exported into a downloadable PDF.
Price: The PlatoForms Free plan includes one live form and 100 monthly submissions. Bronze costs $10/month billed annually ($120/year), or $12 month-to-month, and adds e-signatures, Workflow, and cloud-drive integration. Choose a plan based on the features and submission volume you need.
6. Jotform Smart PDF Forms: PDF Output with a General Form Builder
Jotform Smart PDF Forms turns an existing document into an online form and writes the responses into the original PDF layout. It deserves consideration when your organization already uses Jotform for other forms.
Price: Jotform Starter is free. Check the current regional plan page for paid pricing and submission limits.
How to Choose a Free Fillable PDF Creator
āFreeā can describe creating a file, collecting a limited number of online responses, or using a temporary trial. Compare the output before comparing the price.
| What you need | What to check |
|---|---|
| A downloadable PDF with editable fields | Can recipients save and reopen their entries in a compatible viewer? |
| A browser form with PDF output | How many live forms and monthly responses does the free plan allow? |
| Signatures or participant steps | Are these included in the plan you tested? |
| A reusable intake packet | Can one response populate the required documents, and what needs paid access? |
Sejda offers free file creation within its tool limits; PlatoForms offers a Free online-form plan and a separate Document Creator export route. Compare each routeās output and allowances. A limited hosted plan can be more useful when you need returned submissions instead of a downloadable blank. Check whether signatures or approval steps are included in the free plan.
The best fillable PDF creator for a one-off file may therefore differ from the best tool for a clinic or supplier application. Once you have chosen the output, follow the PDF form creation guide to explore the PlatoForms route.
Test the Output You Actually Need
For a downloadable PDF, enter sample data, save it, close it, and reopen it in the recipient’s viewer. Check tab order, required fields, long text, and signatures. Printing to PDF may flatten fields, so test the exact export command you will use.
For hosted intake, submit on a phone, inspect the generated PDF, pass it to the next participant, and retrieve the final record from its destination. That test shows whether the form is easy to complete and whether your team receives the documents it needs.
