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.

The modern Bates numbering software
BatesFast is Bates numbering software built for the way legal and records teams actually work today. Traditional Bates numbering programs run as heavy desktop installs or, worse, upload your confidential discovery to a remote server before stamping it. BatesFast does neither — it is a Bates numbering program that runs entirely inside your web browser, so sensitive files never leave your device.
Apply sequential Bates numbers to PDFs, JPEGs, PNGs, and TIFFs with custom prefixes, suffixes, zero-padding, and pixel-perfect placement. Batch-stamp entire folders, rename files by Bates range, strip old stamps, and generate Avery label sheets — all from one fast, court-ready Bates stamping tool. Because processing is client-side and powered by WebAssembly, this legal document numbering software handles gigabytes of records in seconds without a network round-trip.
Whether you are a paralegal preparing a production set, a litigation support specialist managing discovery, or a medical-records team indexing charts, BatesFast gives you professional Bates numbering software with no subscription — one free preview run, then a single one-time purchase.
What is Bates numbering?
Bates numbering is the practice of stamping every page of a document set with a unique, sequential identifier — typically a prefix plus a zero-padded number, such as DEF-000001. Named after the Bates Manufacturing Company's automatic numbering stamp, it gives legal, medical, and compliance teams a dependable way to index, reference, and authenticate pages throughout discovery, production, and review.
Bates numbering software vs. a desktop Bates numbering program
A traditional desktop Bates numbering program has to be installed, licensed per machine, and updated by hand — and cloud tools solve that only by uploading your privileged documents to someone else's server. BatesFast is browser-based Bates numbering software: it loads instantly in Chrome, Edge, Safari, or Firefox on Windows and Mac, installs optionally as an offline PWA, and never transmits a single page. You get the convenience of an online tool with the confidentiality of a fully local Bates stamping program.
