Is my PDF form uploaded?

No. The form is filled in and saved inside your browser. Your answers and the file never leave your device.

Will my answers still be there when I open the PDF elsewhere?

Yes. The answers are saved as real form values, so they show up in Adobe Acrobat, macOS Preview, Chrome, Edge and other readers, and the form can still be edited there. Flatten the form if the answers should no longer be editable.

Can I sign the form too?

Yes. Use the Sign tool to draw, type or upload your signature and place it anywhere on the page. This adds a visible signature image, not a certificate-based digital signature.

Why can I not type into my form?

Either the PDF has no form fields, in which case you can use the Text tool to type anywhere on the page, or it is a dynamic XFA form, which only Adobe Acrobat Reader can fill. The tool tells you which one it is.

Can I fill a password-protected form?

Remove the password first with Unlock PDF, fill the form here, and add the password back with Protect PDF if needed.

Fill PDF Forms Online — Free, Private, No Upload

Open a fillable PDF, type your answers, tick the boxes, sign it, and download it with everything saved. It all happens in your browser, so the form never leaves your device.

How to fill out a PDF form online

Drop the PDF form onto the box above. If it has fillable fields, they light up and Fill form is selected.
Click a field and type. Tick checkboxes, choose radio buttons and pick from drop-down lists. Use the page list on the left for multi-page forms; your answers stay when you switch pages.
To sign, click Sign and draw, type or upload your signature, then place it on the page. Other tools let you add notes, highlights or a date anywhere.
Click Download PDF. Tick flatten form first if the answers should no longer be editable.

Your answers are saved properly

Many free tools only paint your text on top of the page, leaving the real form fields empty underneath. Here the answers are written into the form fields themselves, so the PDF opens with them filled in Adobe Acrobat, macOS Preview, Chrome, Edge and other readers, and you or the recipient can still change them there. Accented and non-Latin letters, such as Č, Ž, Ñ, Greek or Cyrillic, are kept.

If the form should be final, flatten it: the answers become part of the page and the fields are removed, which also stops them from being changed by accident.

Private by design

Forms tend to hold the most personal data people have: tax numbers, addresses, bank details, health information. This tool runs entirely in your browser tab, so the form and your answers are never uploaded, stored or seen by anyone else. There is no account and nothing to install.

What it can and cannot fill

Works: standard fillable PDF forms (AcroForms) made in Acrobat, Word, LibreOffice and most form builders, including government forms such as the IRS W-9. Text boxes, multi-line boxes, checkboxes, radio buttons and drop-down lists are supported.
Not supported: dynamic XFA forms, which only Adobe Acrobat Reader can fill. The tool tells you when it sees one. Form scripts that calculate totals or validate answers do not run, so check any calculated fields yourself.
No fields? A scanned or flat PDF has nothing to click into. Use the Text tool to type anywhere on the page instead.
Signatures: the Sign tool adds a visible signature image. It is not a certificate-based digital signature.

Is the form password-protected?

Remove the password with Unlock PDF, fill the form here, then add a password again with Protect PDF before sending it on.
