Tamper-evident.
Every signed PDF is cryptographically sealed. Change one character afterward and the signature breaks.

Batch sign vendor agreements in seconds
Vendor onboarding creates a trail of agreements, tax forms, authorizations, and acknowledgments that all need the same company signature. PDFBatchSigner does the repeat work in one pass.
No account. No subscription. No server.
Live demo — Add documents to see each file auto-matched to a template, then sign the batch. Nothing leaves this page.
The specific problem
Vendor Agreements usually means vendor agreement, supplier packet, payment authorization, W-9, and credit form. The names change. The signature work does not.
That is why this page exists for batch sign vendor agreements, not for generic PDF signing. This is for the stack, the repeat fields, and the moment where one-by-one signing stops making sense.
How it works for vendor agreements
01
Template the repeat spot.
Mark repeat company signature blocks in supplier packets on a sample PDF. Keep the template for the next batch.
02
Drop the stack.
Add the folder of PDFs. PDFBatchSigner looks for the same form structure and places the signature where it belongs.
03
Review, then seal.
Keep the company signature or seal ready without rebuilding every packet from scratch. One look, one click, tamper-evident output in the folder you choose.
Real signatures, not just pictures of one.
Shows in any reader.
This is a verifiable PDF signature built into the file, not an image pasted on a page.
Really you.
Use the Secure Enclave-protected device key by default, or import your own .p12 certificate.
Two ways to sign, your choice.
Default
Secure Enclave key
PDFBatchSigner signs with a secure key generated on your device and protected by Apple's Secure Enclave. Nothing to buy, nothing to set up, fully offline.
Advanced
Bring your own .p12
Already have a signing certificate from a trusted authority? Import your .p12 and your signatures carry your verified identity, recognized in Adobe Acrobat and beyond.

FAQ
Can I batch sign vendor agreements on iPad?
Yes. PDFBatchSigner works on Mac, iPhone, and iPad, with templates and signatures synced through your own iCloud.
Are these real PDF signatures?
Yes. Each signed PDF is cryptographically sealed. If the file changes afterward, the signature breaks and PDF readers can show that the document was altered.
Do my vendor agreements leave my device?
No files go to a PDFBatchSigner server. Signing happens on your device; templates and signatures sync through your own iCloud.
Can I use my own signing certificate?
Yes. The default key is generated on your device and protected by Apple's Secure Enclave. If you already have a trusted signing certificate, import your .p12 for a certificate-backed identity.
Can I keep a company seal as a signature?
Yes. Add it to the signature library and apply it to the right template zone.
