Frequently asked questions
Is FillThisPDF really free?
Yes. You can fill and download a PDF without a subscription, trial, account, payment card or watermark.
Is my document uploaded to a server?
No. Manual PDF editing and exporting happen in your browser. Your file is not uploaded for the free editor. Avoid entering real personal information in the sample form.
Can I fill a scanned or non-fillable PDF?
You can place new text, dates or checkmarks on the page, including scanned PDFs. This does not recognize, remove or replace text already printed in the document.
Will the completed PDF open in Adobe Acrobat?
The download is a standard PDF, and the export is tested for Acrobat compatibility. Some password-protected, XFA or unusually structured files may not be supported.
Can I add a signature to a PDF?
You can add a typed name or signature-style text. This is not a certified digital signature or identity verification.
