How to fill out a PDF form in four steps

  1. 1Drop the form in the box. Scanned forms and photos of paper forms work too.
  2. 2Tap «Text» and then tap the blank where it goes. Type your answer.
  3. 3Add the date and your initials with their buttons, wherever the form asks.
  4. 4Sign and download. Draw your signature, place it on the line and save the PDF.

Drag any box to line it up with the blank. Pull the corner to make it bigger or smaller.

Forms that work best

  • Rental and job applications
  • Tax and payroll forms from an employer
  • School enrollment and permission forms
  • Insurance claims and medical intake forms
  • Any scanned paper form with blank lines

The tool writes on top of the page. It works the same on a form with fillable fields and on a flat scan.

Fill it out on your phone

Open this page in your phone browser. Zoom with two fingers to reach small blanks. The brown bar at the bottom downloads the filled form.

Tips for a clean filled form

  • Zoom in first. Small blanks are easier to hit at a larger size.
  • Keep one text box per blank. It lines up better than one long box with spaces.
  • Write dates the way the form asks, such as MM/DD/YYYY in the US.

Your answers stay private

Forms carry names, addresses and ID numbers. Here the file is filled inside your browser and never uploaded.

Leave «Add signature certificate» checked if the form gets signed. It adds a page with the date and the fingerprint of the original.

Is a signed PDF legally valid?

Yes, in most cases. In the US the ESIGN Act and state UETA laws give electronic signatures the same effect as ink.

The Philippines, India and the UK have their own electronic signature laws. Contracts, forms and receipts signed this way hold up in all of them.

Some documents still need ink or a notary. Wills, many powers of attorney and real estate deeds are the usual examples. Our guide to wet signatures lists them.

When someone else has to sign

Send the PDF from a free SignSolú account. The other person gets a link by WhatsApp or email.

They open it on their phone and tap the brown bar that says «Sign as …». You get the PDF back with a certificate that SignSolú timestamps. Your first ten documents are free.

Frequently asked questions

Can I fill out a PDF form for free?

Yes. No account, no daily limit and no watermark.

Does it work with a scanned form?

Yes. Type on top of the scan wherever there is a blank.

Can I save and finish later?

No. Download the filled PDF and open it here again to add more.

Can I check boxes?

Yes. Use «Text», type an X and place it inside the box.

What time does the certificate show?

The time on your device. With a SignSolú account the time comes from SignSolú and the document can be checked online.

Does the signed PDF carry a watermark?

No. A small gray line at the foot of the last page says «Made with SignSolú · signsolu.com». It covers nothing.
