Why Choose Our PDF Signature Tool?

Complete Privacy

Your PDF never leaves your device. Online signature tools upload documents to remote servers. LocalPDF signs documents locally using client-side processing.

Multiple Signature Types

Draw freehand signatures with mouse/trackpad, upload signature images (PNG/JPG), or use typed text signatures. Maximum flexibility for your signing needs.

No Account Required

Most signature tools require account creation and limit free signatures. LocalPDF works instantly without signup and has no usage limits during beta.

Legally Binding

Digital signatures added with LocalPDF are as legally valid as hand signatures in most jurisdictions (check local laws for specific requirements).

Professional Output

Signatures are embedded as high-quality vector/raster images positioned precisely where you want them. No pixelation or quality loss.

Batch Signing

Sign multiple PDFs with the same signature without re-drawing or re-uploading. Ideal for contracts, invoices, and batch document workflows.
