Free Developer Tools
Client-side encoders, converters and a hash generator — plus an HTTP request logger.
About these tools
This page lists every tool on What Am I Sending. The encoders, the converter and the hash generator all run client-side, so the text you paste never leaves your browser, and none of them require an account.
The HTTP request logger is the one tool that stores something: it gives you a URL that captures incoming requests so you can inspect and replay them. Those requests are deleted automatically after 5 days.
All tools
- Base64 Encoding / Decoding — Encode text to Base64, or decode Base64 back to readable text.
- URL Encoding / Decoding — Percent-encode text for URLs, or decode %XX sequences back to plain text.
- XML Encoding / Decoding — Escape the five XML characters as entities, or decode entities back to text.
- JSON ⇄ YAML Converter — Convert JSON to YAML or YAML to JSON without leaving the browser.
- Hash Generator — Generate MD5, SHA-1, SHA-256, SHA-512, SHA-3 and RIPEMD-160 digests.
When to use it
