Batch sign offer letters in seconds
Offer letters are exciting for the candidate. For HR, they can become a stack of nearly identical signature pages. 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
Offer Letters usually means offer letter, candidate packet, start date, HR signature, and employment terms. The names change. The signature work does not.
That is why this page exists for batch sign offer letters, 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 offer letters
01
Template the repeat spot.
Mark HR or company signature blocks on offer letters 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.
Sign a hiring batch without turning every candidate file into a separate chore. 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.

FAQ
Can I batch sign offer letters 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 offer letters 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 offer letters without an account?
Yes. PDFBatchSigner has no account system; signing happens on your device.
