PDF Form Auto-Filler

PDF Form Auto-Filler

Upload a PDF, Word (.docx) or OpenDocument (.odt) form, fill its fields in a simple form, and download the completed file. Runs entirely in your browser.

Your PDF never leaves your device — everything runs in your browser.

Fill PDF forms online — free, private, no upload

Stop printing, hand-filling and scanning forms back in. This free online PDF form filler reads a fillable PDF (or a Word/ODT form), auto-detects every field, and lets you type your answers in a clean, simple form — then download the completed file. It all runs in your browser, so the personal details you enter never leave your device: no upload, no account, no tracking.

How to fill a PDF form online

Completing a form takes about a minute:

  1. Open your form — drag a fillable PDF, .docx or .odt onto the page, or click to choose it. It loads on your device; nothing is uploaded.
  2. Let it detect the fields — the tool extracts the form’s text boxes, checkboxes, radio buttons and dropdowns automatically.
  3. Fill it in — type your answers in the generated form; each entry maps back to the right field in the document.
  4. Download — export the completed PDF, ready to email, print or submit. Need a signature? Add one in the PDF Editor.

Why fill forms here

  • Completely private. Forms hold personal data. Here everything is processed on your device and never transmitted, so nothing can be stored or leaked.
  • Automatic field detection. No fiddly clicking around the page — the tool finds the fields for you and lays them out in order.
  • Free with no watermark. Fill and download as many forms as you like; the finished file is clean, with no sign-up and no branding.
  • PDF and Word forms. Works with fillable PDFs plus Word .docx and OpenDocument .odt forms — no format juggling.

Forms people fill here

  • Applications. Job, admission, bank or visa application forms that arrive as fillable PDFs.
  • Government & tax forms. Official forms where the fields are already defined — just type and download.
  • Contracts & agreements. Complete the blanks in an agreement, then sign it in the PDF Editor.
  • Onboarding paperwork. HR and onboarding packets that need the same details entered quickly.

Frequently asked questions

Is the PDF form filler free?

Yes. Filling and downloading forms is completely free — no account, no trial and no watermark on the finished file.

Are my documents uploaded anywhere?

No. Your form is opened and filled entirely in your browser on your own device, so nothing is sent to a server. This is important because forms often contain personal details.

What kinds of forms can I fill?

Fillable PDFs (AcroForms), Word .docx and OpenDocument .odt forms. The tool reads the form’s fields automatically and builds a simple form for you to type into.

My PDF is not fillable — can I still complete it?

Yes. If a PDF has no form fields (a flat or scanned form), open it in the PDF Editor instead, where you can type text anywhere on the page and tick boxes, then export.

How does field auto-detection work?

When you open a form, the tool extracts its interactive fields — text boxes, checkboxes, radio buttons and dropdowns — and lists them so you can fill each one without hunting around the page.

Can I sign the form?

Yes. After filling the fields, open the file in the PDF Editor to add a drawn or typed signature anywhere before you download.

Can I download the completed form?

Yes. When you are done, download the filled PDF straight to your device — ready to email, print or submit.

Does it work on mobile?

Yes. It runs in any modern mobile or desktop browser with no app to install.
