Features

Everything you need to build professional PDF forms

Visual Drag & Drop

Click to drop fields exactly where you want them. Grid snap and zoom keep every field pixel-aligned — no coordinates, no code.

Import Any PDF

Open an existing PDF and start editing in seconds. Fields already in the document are detected and imported automatically.

Every Field Type

Text, checkbox, radio, dropdown, signature, date, and number fields — everything a professional form needs. See every field type

Live Preview

Fill your form in a real preview before you ship it, so you catch layout issues while they still take one click to fix.

Privacy by Design

Your documents never leave your device. Every PDF is processed in your browser — no uploads, no server, no exceptions. How privacy works

Export Anywhere

Export a standards-compliant fillable PDF that just works in Adobe Reader, macOS Preview, Chrome, and Firefox.

How It Works

Three steps to a fillable PDF

No installs, no sign-up, no learning curve — go from a flat PDF to a working fillable form in minutes.

  1. Import your PDF

    Drag any PDF onto the canvas or pick a file — it opens instantly in your browser. Existing form fields are detected and imported automatically. Nothing is uploaded to a server.

  2. Place your fields

    Pick a field type — text, checkbox, dropdown, signature, date, number — and click to drop it on the page. Fine-tune the name, size, and validation in the properties panel.

FAQ

Common questions

Is FormForge really free?
Yes — FormForge is 100% free to use, with no account, no credit card, and no paywalled features. It runs entirely in your browser, so there are no servers to pay for and nothing to sell you. Every tool is available at no cost right now.
Are my PDF files uploaded anywhere?
No. Every PDF is opened, edited, and exported locally in your browser, and your files never leave your device or get sent to any server. That makes FormForge safe for confidential contracts, HR paperwork, and other sensitive documents. You can confirm it yourself by watching your browser’s network tab while you work.
Do I need to install anything or create an account?
No. FormForge is a web app that runs directly in your browser — there’s nothing to download or install, and no sign-up, login, or account is required. Just open the site and start building your form.
Can I make an existing PDF fillable?
Yes. Open any regular PDF and drag fillable fields — text boxes, checkboxes, dropdowns, and more — onto the exact spots where people need to enter information. When you export, FormForge saves it as a standard fillable PDF form that anyone can complete.
Can I edit a PDF that already has form fields?
Yes. When you open a PDF, FormForge automatically detects and imports its existing form fields so you can see them on the page. From there you can move, resize, rename, or delete those fields and add new ones alongside them.
Which field types are supported?
FormForge supports seven field types: text, checkbox, radio button, dropdown, signature, date, and number. Each field has configurable properties such as name, required/read-only state, default value, font size, and dimensions.
Will the exported PDF work in Adobe Reader, Preview, and mobile viewers?
Yes. FormForge exports standard AcroForm fillable PDFs that open and fill in Adobe Acrobat Reader, macOS Preview, Chrome, Firefox, and mobile PDF apps on iOS and Android. Because it uses the standard PDF form format, the fields behave the same across viewers.
Does it work offline?
Partly. All editing and PDF processing happen locally in your browser, so once the page has loaded you can keep working even if your internet connection drops. FormForge isn’t an installable offline app, though, so opening or reloading the page still needs a connection to fetch it.
Can I add a signature field?
Yes. FormForge includes a dedicated signature field you can place anywhere on the page to mark where someone should sign. It exports as a standard fillable form field, giving recipients a clear signing area in their PDF viewer. Note that this is a form field, not a certificate-based digital signature.
Is there a file size or page limit?
No. FormForge doesn’t impose a fixed file-size or page-count limit on the PDFs you open. Since everything is processed in your browser, very large or high-page-count documents are ultimately bounded by your device’s available memory rather than a hard cap.
How is this different from Adobe Acrobat or other paid tools?
FormForge is free and runs entirely in your browser — no subscription, no install, and no account. Adobe Acrobat’s form tools sit behind a paid subscription and desktop software. FormForge focuses specifically on creating and editing fillable PDF forms while keeping your files on your device.
Does it work on Mac, Windows, Linux, and tablets?
Yes. FormForge runs in any modern web browser, so it works on macOS, Windows, and Linux, as well as on tablets. There’s no separate app to install — the same site works across every platform with a supported browser.
What happens to my work if I close the tab?
Your work is safe. FormForge continuously auto-saves your form to your browser’s local IndexedDB storage as you edit, and it also saves right before the tab closes. When you return, your draft is waiting on the start screen so you can pick up where you left off.
