Edit & Optimize
Fill in PDF forms in your browser.
Open a fillable PDF and Pyrbit PDF lists every field — text boxes, checkboxes and dropdowns — so you can complete the form and save a filled copy, without printing it or sending it to a server.

How it works
Fill PDF Forms in three steps.
Choose the PDF form
Pick a PDF that has fillable fields. The tool reads them and shows each one by name.
Fill in the fields
Type text, tick checkboxes and pick dropdown options. Turn on Flatten if the answers should become a fixed part of the page.
Save the completed form
The form is filled using its own rules and calculations, and the finished PDF is saved to your device.
What you can do
What Fill PDF Forms does.
- Text fields, multi-line fields, checkboxes and dropdown choices
- Uses the form’s own formatting rules and calculations
- Optional flattening so answers can’t be changed afterwards
- No fields? Open the PDF in Add Text and type on the page instead
In the apps: In the Pyrbit PDF apps you can also build a new fillable form from scratch, with text, number, date, checkbox, radio, dropdown and signature fields.
Private by design
Your PDF never leaves your device.
Fill PDF Forms runs inside your browser tab. The file you choose is read from your device, processed there, and the result is saved back to your device — it is never uploaded to a Pyrbit server, so there is no copy to keep or delete.
Processed in your browser
The Pyrbit PDF engine runs on your computer or phone, not in the cloud.
No upload
Your document isn’t sent anywhere — not to us, and not to a third-party converter.
Sign-in is for your plan only
Your Google account keeps track of your free daily document and Pyrbit Pro. It never gives us your files.
Prefer offline?
The Pyrbit PDF apps do the same work on your phone, tablet or Mac — even without a connection.

FAQ
Fill PDF Forms questions.
How do I know if my PDF has fillable fields?
Open it in the tool. If the PDF has form fields, they are listed straight away; if not, the tool says so and offers Add Text, which lets you type anywhere on the page.
What does “Flatten after filling” do?
It merges your answers into the page content, so the result looks the same everywhere and the fields can no longer be edited. Leave it off if someone else still needs to change the form.
Are radio buttons and signature fields supported?
Text fields, checkboxes and dropdowns are filled in this tool. Signature fields are skipped — use Sign PDF to place your signature on the page.
Is Fill PDF Forms free?
On the web, sign in with a Google account and you can use Fill PDF Forms — or any other tool — on one free document every 24 hours. Pyrbit Pro (₹79/month or ₹599/year) gives unlimited use with no ads. The Pyrbit PDF apps for iPhone, iPad and Android are free, supported by ads.
