Sign a PDF without upload
If you do not want to upload a private PDF, use LocalSign to add a signature mark locally in your browser. The file stays on your device while you edit and export.
Why this is useful
Documents that need signatures can include names, addresses, financial details, or agreements. Keeping the workflow in the browser avoids sending that document to a third-party server.
How to use it
- Open LocalSign and select your PDF.
- Draw or upload a signature.
- Place it on the correct page and add any text or date you need.
- Download the finished PDF.
Good to know
- Adds a signature mark only; it is not a verified identity workflow.
- No certified, qualified, or court-approved signature claims are made.
- Your browser must have enough memory for the PDF.
FAQ
What does 'without upload' mean?
The PDF is read and edited in your browser. LocalSign does not send it to a server.
Do I need an account?

Can I use a sample first?
Yes. The homepage includes a sample PDF button so you can try the editor before choosing your own file.
Privacy & honesty
Your documents stay on your device — LocalSign has no servers that receive your files. Signatures, stamps, highlights, shapes, and other annotations are visual changes created by you. LocalSign does not verify, certify, notarize, or legally validate documents.
