Lightweight developer utilities for JSON inspection and Base64 text encoding, built around local browser execution.
Each page is built around one clear task.
Use JSON Formatter to pretty-print, minify and validate strict JSON syntax. Use Base64 Encode / Decode to convert UTF-8 text to standard Base64 or Base64URL and back.
These tools are intentionally narrow: JSON formatting does not repair malformed data, and the Base64 utility is text-focused rather than a file encoder.
Both current developer utilities execute their core transformations in the browser. JSON uses native parsing and serialization, while Base64 uses browser byte and text encoding APIs.
Local execution reduces the need to send pasted payloads to a Toolmera processing endpoint, but Base64 itself should never be confused with encryption or secret storage.
