How to Add Initials to a PDF (Free, Private)

Add your initials in four steps

• Open the PDF in a local editor by dragging it in or choosing the file.
• Pick the signature tool and either draw your initials with the mouse or type them to render in a handwriting-style font.
• Drop the initials onto the first 'Initial here' spot and resize the box to fit the line.
• Download the finished PDF straight to your computer.

Draw your initials or type them

Drawing produces a handwritten-looking mark. Use your mouse or trackpad to trace your initials in the signature pad — a natural fit for agreements that expect a personal touch.

Typing is quicker: enter your initials (for example, JR) and the editor renders them in a script font. That suits routine sign-offs where a clean, legible mark is all that's needed.

Either way, the initials land as a small graphic on top of the page, so they sit neatly over the line and leave the original content untouched.

Reuse the same initials on every page

Long agreements often ask you to initial the bottom of every page, not only sign at the end. After you've built your initials, there's no need to redraw them page after page.

Drop your mark on page one, then add the same one to each page that calls for it and nudge it onto the line. Since it's the same graphic each time, your initials stay consistent throughout the document instead of drifting from one page to the next.

• Build the initials once at the start.
• Add the same mark to each page that has an 'Initial here' marker.
• Drag to position and resize so it aligns with the printed line.
• Place your full signature on the final page if the document also asks for one.

Initials on a scanned or photographed page

If your PDF is a scan or photo of a paper document, the text isn't editable — but you don't need to edit it in order to initial it. You can place your drawn or typed initials directly over the scanned image, right where the line sits.

It behaves the same as initialing a digital PDF: the mark is a layer above the page, so it prints and exports exactly where you positioned it.

Why local editing matters for signed documents

The documents that need your initials tend to be sensitive: leases, NDAs, employment contracts, and financial agreements. A local, in-browser editor keeps that file on your machine — it's read into the browser, edited there, and saved back without being sent to a server.

Want proof? Open your browser's Network tab while you work and you'll see no request carrying your file. The finished PDF downloads with no watermark and no account required.
