About Base64 String Splitter

Slice massive base64 payloads into smaller chunks of custom byte/character limits for headers, files, or JSON. It's built for encoding, hashing and cryptographic workflows where an exact, reversible transform matters, runs instantly, and works on any device — no install, no sign-up.

How to use Base64 String Splitter

  1. Paste or type your input into the editor on the left.
  2. Leave the defaults, or tweak them if the tool exposes options.
  3. The result appears instantly on the right — everything runs in your browser, so nothing is uploaded.
  4. Copy the output, or download it, and you're done.

Why use Base64 String Splitter?

  • Fast and local — the transform happens in your browser, so there's no round-trip and no waiting.
  • Private by default — your input never leaves your device.
  • Accurate — the same, well-tested logic powers both this page and the public API.
  • Free — unlimited use in the browser, with an optional API for automation.

Use it from the API

Everything this page does is also available as a REST endpoint, so you can call Base64 String Splitter from your own code, a script or a CI pipeline.

Bash
curl "https://api.toolsxpo.com/v1/base64-splitter" \
  -H "Authorization: Bearer txp_live_YOUR_KEY"

The endpoint returns a JSON envelope ({ ok, data, meta }) and costs 1 credit per successful call. Try it in the playground or browse the full API reference.
