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. It is a sound choice for contracts, letters, and forms you would not want sitting on someone else's server.

The editor creates a separate signed copy and does not modify the source PDF in your folder. Signature drawings, uploaded images, and page previews live only in the current browser session. Close or reload the page to clear that working state.

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.

The Sign menu keeps full signatures and initials as separate saved items during the session. After the first mark is placed, use New signature, New initials, or a saved item to place another. An uploaded image is handled locally; a tightly cropped transparent PNG usually needs the least resizing.

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.

Use the page controls to move through a long PDF while the signature remains selected. Undo and redo reverse editing changes, and a selected mark can be removed before export. Zoom changes only the editor view, not the size or quality of the saved page.

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. This is the quick way through an agreement that needs a signature on every page. Each copy lands in the same spot on its own page, so you can then drag or resize any of them on its own. Before you start, note that the signature pad does not reopen automatically after your first placement, so make your signature, place it, and copy it from there. The Sign menu can still create another signature or initials when a document needs more than one mark.

Copies placed with All pages share the starting position but remain separate objects. Move or resize a copy on one page without shifting the others. Use Last page for agreements that need a final execution signature rather than initials throughout.

If the PDF needs an open password, an inline unlock box appears before the editor. Enter the known password and choose Unlock, or skip the file. The password is used inside the browser and is not uploaded.

After a successful unlock, the decrypted working copy opens in the signature editor. The signed download is not re-encrypted, so use Protect PDF afterward when the finished document should require a password. A forgotten open password cannot be bypassed here.

Adding a signature leaves your document intact and draws your mark on top. The details below explain the result:

• 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 drawn, typed, or uploaded signature, in black, blue, or red ink.
• A certified digital signature with a cryptographic certificate. This adds a visible signature, not a certificate.

A visible electronic signature records the mark on the page but does not prove identity through a certificate authority. Acceptance depends on the document, the parties, and local rules. Use a certificate-based signing service when the recipient requires cryptographic validation, a timestamp, or a formal audit trail.

Existing text and images remain on the PDF page, and the placed signature is baked into the exported copy. Review the signer name, page, position, and final filename before sending it, especially when several people will sign in sequence.

When uploading a signature, crop the image close to the ink before adding it. A large white border makes the visible mark look small inside its selection box. A transparent PNG blends into coloured form fields most cleanly, while a JPG keeps its photographed background.

Use an image with enough resolution to stay sharp at the intended size, but avoid a full camera photo when a small crop will do. The editor preserves the image proportions as the corner handle is dragged. Check the preview at normal zoom before saving so the mark does not look stretched, fuzzy, or noticeably darker than the surrounding form text.

Black suits most printed forms. Blue can distinguish an electronic signature from black body text, and red is available when a review process calls for it. The colour picker affects drawn and typed marks; an uploaded image keeps the colours already present in the file.

On a shared computer, avoid leaving a signature image in the Downloads folder after use. The browser session is local, but the source image remains wherever it was selected from. Close the page when finished to clear the editor's saved signature and initials.

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 server copy.

The result panel keeps the generated file available for Download again and Share. It also links to follow-on tools for protection, compression, merging, or organization. Open the downloaded copy once to confirm the signature appears on the intended page and that the total page count matches the source. Check the mark at normal zoom and confirm no signature copy covers nearby dates, names, checkboxes, or form instructions.

Yes. This tool works in current desktop and mobile browsers 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.
