About String Padding Utility

Pad string values to target lengths with custom characters at the beginning or end of lines. It's built for string manipulation and text-processing tasks, runs instantly, and works on any device — no install, no sign-up.

How to use String Padding Utility

  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 String Padding Utility?

  • 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 String Padding Utility from your own code, a script or a CI pipeline.

Bash
curl "https://api.toolsxpo.com/v1/string-padder" \
  -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.
