Is a typed signature legally binding?

In many jurisdictions a clear intention to sign is enough for ordinary commercial documents, but rules vary by country and contract type. Check with a professional for anything significant.

Can I use an image of my handwritten signature?

The current tool inserts a text signature block. For a handwritten image, add it with the Watermark tool positioned on the signature page.

Where are my files processed?

In your own browser. The file is read into memory on your device, rewritten there, and offered back to you as a download. It is not uploaded to a server, stored, or shared with anyone.

Is there a cost, sign-up or watermark?

No. Every tool on Be My PDF is free to use without an account, and nothing we produce carries a Be My PDF watermark or badge.

About Sign PDF

The print–sign–scan cycle is the slowest part of most agreements, and each round trip degrades the document. Adding a signature block directly to the PDF removes the printer from the process entirely.

This tool places a signature line with your name and the date on the final page, producing a document ready to return by email.

How to use Sign PDF

Step 1
Upload the PDF
Add the document to sign.
Step 2
Enter your details
Provide the name that should appear on the signature line.
Step 3
Download
Save the signed document and send it back.

When it helps

• Returning a contract without access to a printer or scanner.
• Signing off delivery notes and timesheets from a phone.
• Approving quotes and purchase orders quickly.
• Adding a dated acknowledgement to a policy document.

Good to know

• This produces a visible signature block, not a cryptographic digital signature with a certificate.
• For legally sensitive agreements requiring identity verification, use a certificate-based e-signature provider.
• The signature is placed on the last page, the conventional position for execution blocks.

Sign PDF: frequently asked questions

How edits are written into a PDF

Layers, not overwrites

PDF was designed as a final-form format: the page describes where every glyph sits, not what the paragraph means. Editing tools therefore work by adding a new layer of drawing instructions on top of the existing content stream — a stamp, a page number, a signature image, a rectangle of colour.

Because the addition sits above the original, the underlying text stays searchable and selectable. That is a feature when you are numbering pages, and something to be aware of when you are covering information: a coloured box hides text visually but does not delete it. Flatten or rasterise the page when the content must genuinely be gone.

Coordinates, points and the bottom-left origin

PDF measures everything in points, where 72 points equal one inch, and its coordinate origin sits at the bottom-left of the page rather than the top-left used by screens. An A4 page is 595 × 842 points; US Letter is 612 × 792.

This is why a margin that looked right on a Letter document shifts slightly on A4, and why placing an element 'twenty from the top' requires subtracting from the page height. Tools that offer margin or position presets handle the arithmetic for you, but knowing the units helps when you need an exact placement.

Fonts, embedding and why text can change appearance

Any text added to a page needs a font program. If the font is embedded, the document renders identically everywhere; if it is merely referenced, the reader substitutes something similar and spacing can shift. Standard base-14 fonts such as Helvetica and Times are assumed to exist in every reader, which is why added labels commonly use them.

Non-Latin scripts are the usual sticking point: a base font that lacks Cyrillic, Arabic or CJK glyphs will render them as blanks or boxes. Keep added annotations in the Latin alphabet, or convert the finished page to an image, when a document must be reproduced exactly on unknown systems.

Common problems and fixes

Added text or numbers overlap existing content: The source pages already use the margin area. Increase the margin setting, move the element to the opposite corner, or add a small white backing box first.
The change is invisible in the preview but present in the file: Browser preview panes cache aggressively. Download the result and open it in a desktop reader before concluding the edit failed.
The edited file is much larger than the original: Raster elements such as signature photographs are stored at full resolution. Crop and shrink the source image, or run a compression pass afterwards.

Terms worth knowing

Flattening: Merging annotations, form fields and overlays permanently into the page content so they can no longer be edited or removed.
Point: The PDF unit of length: 1/72 of an inch, so 72 points make one inch.
Base-14 fonts: The fourteen typefaces every conforming PDF reader must provide, including Helvetica, Times and Courier.
