Sign Documents

About the Tool

When a client or partner sends a contract, the last thing you want to do is print the file, sign it with a pen, and scan it back. It breaks your workflow and looks unprofessional. We built this sign pdf online tool to give you a fast, native way to apply digital signatures to your documents exactly where they belong.

Whether you need to authorize a quick invoice, execute a non-disclosure agreement, or sign off on a multi-page legal bundle, this tool allows you to legally bind documents in seconds. You can draw your signature, type it in a professional cursive font, or upload a stamp you already use.

How to Use

We designed the signing process to mimic the ease of stamping a physical document on your desk. Here is the frictionless guide:

1. Create your signature: Start by drawing your signature on the digital pad, typing your name, or uploading a high-resolution image of your existing signature.
2. Upload your document: Drag and drop your `.pdf` or supported image file into the drop zone. The tool will instantly render a live preview of your file.
3. Place and size: Your signature will appear over the document. Drag it to the correct dotted line and use the corner handles to resize it perfectly. For multi-page PDFs, use the navigation arrows to flip to the correct page.
4. Apply and download: Once the placement is perfect, click the button to apply the signature. The engine will permanently embed the signature into the document architecture and provide an instant download.

How long we keep your signed document

Documents requiring signatures inherently contain highly sensitive material. Non-disclosure agreements, tax forms, and employment contracts must be protected. We engineered our conversion engine with strict privacy protocols.

For standard files under 5 MB, we process the signature placement entirely inside your local browser memory. The document is never transmitted over the internet, and we never see the contents.

Files over 5 MB go to our server over an encrypted connection. We do not extract your personal data and we do not keep a signature profile. Both the original and the signed copy are removed by a cleanup job that runs every thirty minutes and removes anything older than an hour, so the real window is up to about ninety minutes. Under the threshold none of that applies, because the file never leaves your device.

Features

Applying a signature digitally should not degrade the quality of the original file. Here is how our engine handles the technical aspects of signing:

• Native Embedding: For PDFs, the engine does not just flatten an image over your document. It natively embeds the signature data into the PDF structure, ensuring the surrounding text remains perfectly crisp and selectable.
• Live Placement Viewer: Instead of guessing where the signature will land, you get a 1:1 scale preview of your document, allowing millimeter-accurate placement.
• Three Creation Modes: Not everyone wants to draw with a mouse. You can quickly generate a professional, legally-binding cursive signature just by typing your name.
• Multi-Format Support: In addition to PDFs, the tool natively supports applying signatures to JPEGs, PNGs, TIFFs, and WebP images.
