Frequently asked questions
Which PDFs can I fill in?
PDFs with form fields (text, checkboxes, lists). If the PDF is just an image or plain text with no fields, the tool tells you.
What does locking the fields mean?
The downloaded PDF has no editable fields: what you filled in becomes part of the page and can no longer be changed.
Is it really free?
Yes, 100% free. No sign-up, no subscription and no usage limits. All Tools123 are free.
