Fill PDF Form Online: Type into a Fillable PDF
Fill in a fillable PDF form in your browser: every text box, checkbox, drop-down, and option list is listed beside a preview showing where it sits on the page, and you can save the completed form to keep editing later, or flatten it so the answers can no longer be changed.
Fill PDF Form Online: Type into a Fillable PDF: The form's fields are read from the PDF itself, its AcroForm, and listed by name with the right kind of control. The values you enter are written back into those fields, and their appearance is redrawn so every reader shows them the same way. Flattening turns the filled fields into ordinary page content. The built-in font covers Latin-script languages; forms in other scripts are best filled in a desktop reader. Runs 100% locally in your browser with zero server file uploads.

Field names
Fields are listed by the names the form's author gave them, which are usually close to the printed labels. The numbers on the preview show which box each one fills.
Checkboxes and radio buttons
Ticking a checkbox or choosing an option uses the form's own on value, so the answer is read correctly by whoever processes the form.
How to use it
- Choose a fillable PDF form.
- Fill in the fields; each one is numbered on the page preview.
- Download the filled PDF, flattened if you want the answers fixed.
Privacy & limitations
Your PDF and your answers stay in your browser and are never uploaded.

Frequently asked questions
Why does it say my PDF has no fields?
The form is probably a scan or a flat printout without fillable fields, or an XFA form made with old Adobe software. For a flat form, add text on top with a PDF editor.
Should I flatten the form?
Flatten it when you send the final version, so nobody can change your answers. Keep an unflattened copy if you might need to edit it.
Can I sign it too?
Yes: save the filled form, then open it in the PDF signer to add your signature.
