Developer Tools

Format, validate and encode the data you work with.

The utilities you reach for a dozen times a day — a JSON formatter that tells you exactly where the syntax broke, Base64 and URL codecs, and a timestamp converter. Nothing is transmitted, so it is safe to paste production payloads.

Most used

JSON FormatterPretty-print or minify JSON, with the exact error position.
Base64 EncoderEncode text or a file to Base64, standard or URL-safe.
Timestamp ConverterUnix time to a readable date, in UTC and your local zone.
