About PDF Signer
ποΈ PDF Signer: sign a pdf in your browser, without uploading it anywhere
PDF Signer is a Chrome extension that turns an unsigned document into a finished one in about ten seconds. Draw your name with the mouse, type it in a handwriting font, or drop in a photo of it. Everything runs on your own machine, so the paperwork you care about never travels to a stranger server. It is the quickest way to sign pdf documents when the alternative is printing, scanning and emailing the result back.
π§ Two ways in
1. Open pdf signer from the toolbar and drop a document into it.
2. Right-click a link to a document on any page and send it to the editor.
π Quick start
1. Click the pdf signer icon in the Chrome toolbar.
2. Drag in a document, or pick one from your computer.
3. Draw, type or upload a pdf signature and drop it where it belongs.

βοΈ Three ways to make a pdf signature
β€ Draw it. Mouse, trackpad or touchscreen. Stroke width follows your speed, so the line looks like real ink, not a flat computer curve.
β€ Type it. Enter your name and pick one of the handwriting fonts β the quickest route when you just need something legible.
β€ Upload it. Sign a sheet of paper, photograph it, and import the PNG or JPG.
Whichever route you pick, the pdf signature stays sharp at any zoom β a real vector mark, not a blurry screenshot.
π A library that remembers you
πΉ Store up to six marks β a full signature, initials, a company stamp.
πΉ Reuse any of them in one click on the next contract.
πΉ Resize, rotate and reposition after placing β nothing is final until you save.
πΉ Undo and redo cover every step, so a misplaced mark costs you a second.
π¦ Batch mode, the part nobody else does
β Load up to ten documents in one session.
β Apply the same signature across all of them.
β Download the whole set as a single ZIP archive.
β Built for a stack of invoices or onboarding forms at quarter end.
π Local by design
π No upload step. The browser reads the bytes and writes them back.
π No telemetry, no analytics, no account database to leak.
π Turn off your wifi and pdf signer still works.
π Your signature stays in local storage on this machine only.
