Web utility

Web utility tools collect 9 focused utilities for url encoding, timestamps, base64, and more. Each page is built around a single task so search users can land directly on the workflow they need.

Common web utility workflows

Base64 Encode/Decode: Convert UTF-8 text to and from Base64.
URL Encode/Decode: Encode or decode URLs and query strings safely.
Timestamp Converter: Convert Unix time and ISO-8601 with time zones.
HTTP Request: Debug API requests with method, auth, headers, query, and body.

Text utilities are local-first in the browser. File and network workflows clearly state when server-assisted processing is required.
