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

Batch sign purchase orders in seconds
Purchase orders are approvals disguised as paperwork. The work is the same signature and date across a pile of supplier PDFs. 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
Purchase Orders usually means purchase order, PO approval, supplier form, amount approval, and procurement request. The names change. The signature work does not.
That is why this page exists for batch sign purchase orders, 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 purchase orders
01
Template the repeat spot.
Mark approval signatures and dates on purchase orders 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.
Drop the approved POs, review the zones, and export the signed folder. 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

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.
A simple PO approval flow
- Export approved POs from finance system

FAQ
Can I batch sign purchase orders 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 purchase orders 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 batch approve and sign POs on Mac?
Yes. Mac is ideal for dropping a full folder and reviewing a larger stack.
Drop the stack, done.
