Built by experts for legal, medical, and compliance professionals

Bates numbering isn't just about adding text to a PDF — it's about compliance, accuracy, and unwavering security. Traditional tools fall short by forcing you to upload gigabytes of sensitive discovery to unknown servers. BatesFast flips the script.

Court-Ready Precision

Whether you need padded zeros, custom prefixes (e.g., DEF-000001), or specialized margins to avoid overwriting content, BatesFast provides pixel-perfect placement every time.

Total Privilege Guarantee

Traditional cloud stamping tools upload your sensitive litigation files to remote servers. BatesFast processes everything locally in RAM on your device. Close the tab, and your data is gone forever.

Unmatched Speed

Bypass the network bottleneck entirely. Because BatesFast doesn't upload or download large discovery bundles, you can stamp gigabytes of documents instantaneously.
