## Complete Fillable PDFs Without Adobe

Tax forms, applications, HR paperwork - fillable PDFs are everywhere, and you shouldn't need expensive software for them. AiLoveKit's **PDF form filler** reads every AcroForm field in your document, gives you a clean input for each one, and writes your answers back into the PDF locally. Choose flattening to lock the form before sending.

## Form-Filling Steps

- Load the fillable PDF - fields are detected automatically.

- Type answers, tick checkboxes, pick dropdown options.

- Download the completed form, flattened or still editable.

Handling sensitive forms? Everything happens in your browser - answers are never transmitted anywhere.

## Frequently Asked Questions

**What form types are supported?**

Fillable PDFs with AcroForm fields: text inputs, checkboxes, radio groups, and dropdown lists.

**What does "flatten" do?**

Flattening merges your answers into the page so fields can no longer be edited - ideal for final submissions.

**My PDF has no fields - what now?**

The tool will report no form fields found. For flat PDFs, use Annotate PDF to add text on top.
