Sign PDF

Yes. Many free signing sites upload your document to their servers to add the signature. This tool does not. Your PDF and your signature are handled right inside your browser, so they are never uploaded, stored, or seen by anyone else. That makes it a sound choice for contracts, letters, and forms you would not want sitting on someone else's server.

Open the signature pad and draw your name with a mouse, a trackpad, or your finger on a touch screen. Prefer to type it? Switch to the type tab and your name is set in a handwriting style you can use straight away. If you already have a photo or a scan of your signature, the upload tab takes that instead, and a PNG with a transparent background sits most cleanly on the page. Ink comes in black, blue, or red, and you can capture your initials the same way, which is handy for pages that ask you to initial as well as sign.

After you draw, type, or upload your signature, click on the page where you want it and it drops in with a live preview. Drag it to nudge it into the right spot, and pull a corner to make it larger or smaller until it sits neatly on the line. Corner handles keep it in proportion, and there is a handle above it for straightening it up. Nothing is fixed until you save, so you can keep adjusting until it looks right.

Place your signature once, and while it is still selected two buttons appear above it: All pages puts a copy on every page, and Last page puts one on the final page only. That is the quick way through an agreement that wants a signature on all of them. Each copy lands in the same spot on its own page, so you can then drag or resize any of them on its own. Worth knowing before you start: the signature pad does not reopen after your first placement, so make your signature, place it, and copy it from there.

If a PDF opens on your device without asking for a password, you can sign it here with no extra steps. If a file is locked and needs a password just to open it, remove that first with our Unlock PDF tool, then bring the unlocked copy back here to sign it.

Adding a signature leaves your document intact and simply draws your mark on top. Here is the honest breakdown so there are no surprises:

• Every page at full quality, with text still sharp and selectable and images at their original resolution.
• A signature you place yourself, and copies on every page or the last page in one tap.
• A signed file that is baked in, so the signature stays put wherever the PDF is opened.
• A certified digital signature with a cryptographic certificate. This adds a visible signature, not a certificate.
• A drawn, typed, or uploaded signature, in black, blue, or red ink.

There is no account to make and nothing to pay. Add a PDF, sign it, and tap Save and download; the signed copy saves with -signed added to the original name, so you can tell the two apart. Because the work happens in this page rather than on a server, signing a document online here costs you no upload time and no privacy.

Yes. This tool works in any modern browser on iPhone, Android, tablets, and computers, with nothing to install. Drawing with a finger on a touch screen often gives the most natural signature. Add your PDF the same way, sign it, and the finished file saves to your device.
