DevTidy › JSON › JSON Minifier

JSON Minifier

Strip whitespace from JSON to make payloads smaller for APIs, config strings and storage. 🔒 Runs locally. Nothing uploaded.

Output

The output is validated JSON, so a broken file is caught before you ship it.

Frequently asked questions

Is my data uploaded?

No. DevTidy runs entirely in your browser. Your input is processed on your device in a background Web Worker and never sent to a server, so it is safe for API keys, customer data and production configs.

Can it handle large files?

Yes. Heavy work runs in a Web Worker so the page stays responsive, and there is no upload size limit. Multi-megabyte inputs are fine; the practical limit is your device memory.
