Encoders & Decoders
Encoding problems hide in plain sight: a double-encoded URL parameter, a JWT claim you need to inspect, or a string with escape sequences that breaks a JSON payload.
These tools convert text to and from Base64, URL encoding, HTML entities, binary and escaped strings, and generate cryptographic hashes so you can verify data integrity.
