Short answer: choose the PDF, draw in the box, set the page and position, then place the signature. The download is a new file; the original is never modified.
Visible signature, and why that is stated
A picture of a signature is what an employer, a landlord or a college form expects. A digital signature is a cryptographic seal that needs a certificate and proves the file was untouched. This tool does the first, and the page says so because “signed PDF” is used for both.
Placing it well
- Position is a percentage of the page, so the same numbers work at any paper size.
- The image keeps its aspect ratio; only the width is set.
- A caption is drawn under the signature in a small, plain typeface.
- Anything that would land off the page is clamped back inside it.
The result is a normal PDF you can still merge or number:add page numbers for a multi-page form, orreorder pages before signing.
