The specific problem
Certificates of Origin usually means certificate of origin, commercial invoice, packing list, customs form, and export packet. The names change. The signature work does not.
That is why this page exists for bulk sign certificates of origin, 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 of origin
01
Template the repeat spot.
Mark company signatures and seals on export document 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 signatures, seals, and templates local while still syncing across Apple devices. 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 a device-generated key protected by Secure Enclave when available, or import a supported .p12 identity.
Two ways to sign, your choice.
Default
Device-protected key
PDFBatchSigner signs with a key generated on your device. It uses Secure Enclave when available and a Keychain-protected fallback otherwise.
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 of origin 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 of origin 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, using Apple's Secure Enclave when available and a Keychain-protected fallback otherwise. You can also import a supported .p12 identity.
Can I use a company seal on export documents?
Yes. Store the seal as a signature asset, place it in the template, then review before signing.
