simple browser-based utilities for json, text, encoding, and everyday dev tasks. everything runs locally in your browser — paste in, copy out, no account required.
json
Format and validate JSON online. Paste minified JSON and get readable indented output — free, private, runs in your browser.
Compress JSON to a single line. Remove whitespace from JSON for configs, API payloads, and production builds.
text

Count words in text. Get word count, sentence count, and reading time estimate for any string or document.

URL-encode special characters for query strings or decode percent-encoded URLs back to readable text.
