Sign & Seal: Batch Stamp PDFs

Create digital stamps and signatures, apply them to PDFs by hand or template, and batch export processed documents with local-first privacy.

Sign & Seal is a professional PDF stamping and signing studio for creating digital stamps, signatures, seals, and document workflows on your device.

Create custom stamps from scratch, draw or type signatures, scan real stamps from photos, and place them directly onto PDF documents. For repeated work, build reusable templates that apply stamps and signatures to the right pages automatically. For high-volume workflows, process multiple PDF files in batch and export the finished documents together.
