Why signing locally is safer
Leases, NDAs, offer letters, invoices, and medical or consent forms are exactly the kind of documents you don't want sitting on someone else's server. PDF Sign Pad signs them the same way it signs anything else: entirely on your own device. Your document and signature are never uploaded, so there's no server copy to leak, get breached, or hand over in a data request — just your document, signed, and downloaded straight back to you.
Common uses
A freelancer signing a client NDA before starting a new project — one file, no account to set up first. A job-seeker signing and returning an offer letter the same day it arrives, from a phone if that's what's handy. A parent filling out and signing a school consent form between errands. A privacy-conscious professional adding a signature to an internal confidential form they'd rather not upload anywhere. Different documents, same job: sign it, download it, done — no account required, and nothing left behind on a server in between.

Einige Antworten unten werden nur auf Englisch angezeigt — der Rest der Oberfläche ist in allen 7 unterstützten Sprachen verfügbar.
Wird mein Dokument irgendwohin hochgeladen?
Nein. Ihr PDF und Ihre Unterschrift werden vollständig auf Ihrem Gerät verarbeitet und verlassen Ihren Browser nie.
Can I sign a PDF online for free — without creating an account?
Yes. PDF Sign Pad is free to use, with no account, no sign-up, and no email address required — not even to save a signature for later. Open the tool, drop in your PDF, sign it with a drawn, typed, uploaded, or saved signature, and download the finished file. Nothing about your document is uploaded anywhere in the process — everything happens in your browser. See the for exactly how it works.
Ist das eine rechtlich bindende Unterschrift?
PDF Sign Pad erstellt eine einfache visuelle elektronische Signatur. Es handelt sich nicht um eine zertifizierte oder qualifizierte digitale Signatur — siehe unseren Haftungsausschluss.
Does signing create a new PDF, or change my original file?
Signing never touches your original file. PDF Sign Pad only ever works with the copy loaded into your browser's memory — the file already saved on your device or in the cloud is untouched unless you choose to overwrite it yourself. When you click Download, the app "flattens" your signature and any text you've added — permanently baking your marks into the pages — and gives you a brand-new, finished PDF to save wherever you like. See the for more on how this works.
Was passiert mit meinem Dokument, nachdem ich den Tab geschlossen habe?
Nichts wird gespeichert. Ihr Dokument, jeglicher hinzugefügter Text und Ihre Unterschrift existieren nur im Speicher Ihres Browsers für diese Sitzung — das Schließen des Tabs, ein Neuladen oder ein Klick auf "Neu beginnen" gibt sie vollständig frei.
