Questions and answers

How do I make a PDF fillable for free?

Open the PDF in the tool at the top of this page and run auto-detect. Check the fields it finds, add any it missed, and download. The result is a fillable PDF.

How do I fill out a PDF form online?

Open the form here, click into each field and type your answers. Tick checkboxes and choose options, then download the filled PDF.

Will the form work in other PDF readers?

Yes. Pagestro adds standard PDF form fields, which common desktop, browser and phone PDF readers can fill in.

How accurate is auto-detect?

It looks for existing form fields, typed blanks made of underscores, dots or dashes, and labels such as “Name:” or “Date:”. Check the result and adjust fields before you share the form.

Can people sign the form?

You can add a marked signature box. To sign it yourself, use Sign PDF. To collect signatures with an audit trail, use Contracts.

Is my form uploaded?

No. The form and your answers stay in your browser on your own device. Nothing is sent to Pagestro.

Why Pagestro

Forms without the form software

  • Flat PDF to fillable form

    Typed blanks like ____ or ....., and labels like “Name:”, become real form fields in one click.

  • Reads existing fields

    Forms that already have fields open ready to fill.

  • Six field types

    Text, checkbox, radio, dropdown, list and signature box.

  • Fill forms on your phone

    Type into the fields from your phone’s browser.

  • Required and read-only

    Mark fields as required or read-only, and let text fields run over several lines.

  • Works in other PDF readers

    Fields are standard PDF form fields, so people can fill them in the reader they already use.

  • Private and free

    The form is built on your device. No upload, no sign-up and no watermark.

Private by design

Personal details stay on your device

Forms ask for addresses, birth dates and ID numbers. Pagestro fills and builds them inside your browser, so what you type is never uploaded.

  • No upload of the form or your answers
  • Everything runs as code inside this page
  • Close the tab and nothing is kept
