Fill PDF Forms — Free, No Sign-Up
Choose a PDF with form fields. The fields appear below as a simple form — fill them in and press Save Filled PDF.
Honest note: this tool fills real form fields already built into your PDF. If your PDF has no form fields, the tool will tell you so plainly — use the PDF Editor instead to add text on top of the page.
How to use Fill PDF Forms
Choose your PDF
Click the box above or drop one PDF file onto it. The tool reads the form fields inside it — text boxes, tick boxes, dropdowns and choices.
Fill in the form
Each field appears below as a simple box to type in, tick or pick from. Fill in what you need; leave the rest blank.
Save the filled PDF
Press “Save Filled PDF”. Your answers are saved into the PDF itself, and the filled file downloads instantly.
Example: Example: an application form with fields for name, email and country — type your name, tick the agreement box, pick your country, save, and the PDF is ready to send.
About Fill PDF Forms
Application forms, contracts and surveys often arrive as fillable PDFs — but filling them in usually means printing, writing by hand and scanning again. PDFTools fills your PDF form right in your browser: it finds the real form fields inside the file, shows them as a simple form to type into, and saves your answers back into the PDF. The filled file opens in any PDF reader with your answers in place.
Text fields, tick boxes, dropdowns and choice groups all work. One honest limit: the tool can only fill PDFs that already have real form fields built in. If your PDF is just a flat scan or plain text with no fields, the tool says so plainly instead of pretending — in that case, use the PDF Editor to add text on top. There is no upload, so your document never leaves your device, and everything is free, with no account and no sign-up.
Frequently asked questions
How do I fill a PDF form online?
Choose your PDF. Its form fields appear below as a simple form — type into the boxes, tick the boxes, pick from the dropdowns — then press “Save Filled PDF”.
My PDF has no fields. What can I do?
This tool only works on PDFs that already have real form fields built in. If your PDF has none, the tool tells you so plainly. Use the PDF Editor instead to add text on top of the page.
Will my answers show in other PDF readers?
Yes. The answers are saved into the PDF's form fields and the field appearances are rebuilt, so the filled values show in Adobe Reader, Chrome, phones and anywhere else.
Can I tick boxes and pick dropdowns too?
Yes. Tick boxes become tick boxes, dropdowns become drop-down lists, and choice groups become lists to pick from — all filled the same way.
Is filling PDF forms free?
Yes. Filling PDF forms on PDFTools is 100% free. There is no paid plan, no page limit and no watermark.
Do my PDF files get uploaded?
No. The filling happens entirely in your browser. Your files never leave your device and nothing is stored on any server.
