    JSON ↔ YAML Converter

    Convert JSON to YAML and back — with honest warnings about what changes.

    Convert JSON to YAML or YAML to JSON with a real YAML 1.2 parser, and see every comment, anchor, merge key, timestamp and out-of-range integer the conversion costs you. Catches the "Norway problem" in both directions. Pure client-side, no upload.

    URL Encoder / Decoder

    Percent-encode, decode, and parse query strings — with per-component RFC 3986 rules.

    Percent-encode a value for the position it actually lands in, decode one that came back mangled, or split a whole URL into its components and a decoded query-parameter table. Double-encoding, + vs %20, punycode hosts and repeated keys are named, not guessed. Pure client-side.

When you reach for Encoding tools.

Encoding tools are the ones you use ten times a day and never think about — until the round trip is not clean and you cannot tell whether the problem is your data, your encoder, or the terminal you pasted through.

Most of the failures are about variants nobody documents. Standard Base64 versus the URL-safe alphabet that swaps + and / for - and _. Whether padding is present. Whether a URL encoder is escaping a whole URL or a single query parameter, which need different treatment for characters like & and =.

These are built to make the variant explicit rather than guessing, and to round-trip losslessly so you can confirm the transformation rather than assume it.
