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

Batch sign certificates in seconds
Certificates are the nicest-looking paperwork and still somehow become a signing assembly line. 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
Certificates usually means completion certificate, training certificate, student certificate, diploma, and award certificate. The names change. The signature work does not.
That is why this page exists for batch sign certificates, 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 certificates
01
Template the repeat spot.
Mark signature placement on certificates with consistent layout 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.
Use one clean certificate template and sign the whole graduating batch. 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 certificates 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 certificates 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 batch sign completion certificates?
Yes. If the certificate layout is consistent, set the signature spot once and sign the batch.
