About Create Fillable PDF

Create PDF Form builds a new fillable PDF from blank pages in your browser. Give the form a title, choose A4 or US Letter, and add the fields a recipient should complete. Each field can be a text box or a checkbox. You control the visible label, the internal PDF field name, and whether the field carries the required flag. When the form is ready, the tool creates a separate PDF download with traditional AcroForm fields. Nothing is uploaded to Lizely, and the original data you enter stays in the current browser session. This narrow workflow is useful for a simple registration sheet, feedback form, consent checklist, intake page, request form, or other document that starts from an empty layout.

The tool intentionally creates a new document; it does not open, inspect, or modify an existing PDF. It cannot convert lines on a scanned form into fields, place controls over an uploaded template, recognize labels automatically, or preserve an existing document design. If you need to make an existing form permanent after it has been filled, use Flatten PDF instead. If you need a signature drawn onto a document, use Sign PDF. This distinction matters because adding interactive controls to arbitrary existing page content requires positioning and compatibility decisions that this basic form builder does not pretend to make.

Generated files use the conventional AcroForm model supported by many desktop and browser PDF viewers. A text field accepts typed text, while a checkbox stores a checked or unchecked state. The required option sets the PDF field's required flag and adds an asterisk to the printed label. Viewer behavior is not identical: some readers highlight required fields, some enforce them only during a submit action, and some provide little visible indication. This tool does not add a submit button, email action, JavaScript validation, digital signature field, dropdown, radio group, date picker, calculation, or server endpoint. Always open the downloaded file in the exact viewer your recipients will use and test filling, saving, reopening, and printing it.

Internal field names are part of the PDF structure, so each name must be unique. Names accept English letters, numbers, spaces, underscores, and hyphens and are limited to 64 characters. Visible labels and the title currently accept printable English characters and are limited to 100 characters because the generated file uses a built-in standard PDF font. These checks reject blank values, duplicates that differ only by capitalization, control characters, unsupported characters, and unsupported field types instead of silently changing the structure. A form must contain at least one field and can contain at most 30. When the current page no longer has safe vertical space, the generator adds another blank page and continues without dropping fields. The result summary reports the actual page and field counts.

Layout is deliberately simple and predictable. Text controls span the usable page width beneath their labels. Checkboxes appear beside their labels. Fields follow the order shown in the editor, and required labels receive an asterisk. The tool does not provide drag-and-drop coordinates, columns, logos, colors, custom fonts, branding, accessibility tagging, tab-order editing, or print-production controls. Long labels fit within the supported input limit but may not suit every page design, so download and inspect the result before distribution. For a polished or regulated document, recreate the form in a professional authoring application and perform the accessibility and compliance review required for that audience.

Generation and download happen locally with the installed pdf-lib library. Changing the title, size, type, name, label, or required option clears the previous result so an old file is not mistaken for the current settings. Repeated generation replaces the prior temporary download URL, and leaving the page releases it. The downloaded PDF is not encrypted, certified, signed, access-controlled, or connected to a database. Anyone with the file may copy or alter it, and entered responses remain inside each recipient's saved PDF unless they send that file elsewhere. Do not use a blank local form alone as a secure collection system for passwords, payment card details, health records, identity documents, or other sensitive information. Choose an appropriately secured service when submissions must be collected, authenticated, retained, audited, or deleted under a policy.

For a reliable handoff, use concise field labels, assign stable internal names, mark required controls only where necessary, and keep the number of fields manageable. Generate the PDF, open it in the target viewer, type into every text field, toggle every checkbox, save a copy, close it, and reopen it to confirm responses persist. Print or preview the pages to check that labels and controls fit. Keep the field plan separately if another person will maintain the document. Create PDF Form is a private, quick starting point for basic fillable PDFs, not a full PDF template editor, response database, electronic-signature platform, or substitute for legal and accessibility review.

Methodology & sources

The tool validates a title and one to 30 uniquely named field definitions, creates a blank A4 or US Letter PDF with pdf-lib, lays out each text box or checkbox in order, sets the PDF required flag when selected, adds continuation pages as vertical space runs out, and saves a separate AcroForm PDF locally. It never reads or modifies an existing PDF.

Frequently asked questions

Can I add fields to an existing PDF?
No. This tool creates a new PDF from blank A4 or US Letter pages. It does not upload, open, or modify an existing PDF or scanned template.
Which fillable field types are supported?
It supports traditional AcroForm text boxes and checkboxes. It does not create dropdowns, radio groups, signature fields, date pickers, submit actions, or calculations.
Does required mean every PDF viewer will block an empty form?
No. The PDF required flag is set, but viewers enforce or display that flag differently. Test the file in the viewer your recipients will use.
Are my form labels or PDF uploaded?
No. The form structure and PDF file are created locally in the current browser, and the download is generated without uploading your entries to Lizely.
What happens when the fields do not fit on one page?
The generator adds another blank page and continues in the same field order. The result reports the actual page and field counts.
