Encoding work belongs next to API debugging

Encoding issues rarely appear in isolation. You discover a broken redirect in staging, copy the query string from HAR files, and realize Unicode was double-encoded. Or you embed user-generated links inside JSON and need a reliable URL encoder / decoder that mirrors encodeURIComponent semantics before you push the payload through an integration test.

The Encoding tools hub groups Base64 text encode and decode, image to Base64 and Base64 to image converters, percent-encoding, QR codes, and image compression—the utilities that show up in the same incident threads. We link outward to JSON formatting when escaped URLs sit inside structured logs, and to the regex tester when you need to extract tokens before decoding them.

Everything here runs client-side. That design choice matters for encoding workflows because query strings frequently contain PII or signed parameters. By keeping transforms in your browser, ToolMorph stays a scratchpad rather than another service in the compliance review path.
