URL Encode then Base64 Double Encode

URL encoding escapes special chars for URLs. Base64 further encodes for binary-safe transport in JSON.

What it solves

URL-encode then Base64-encode for double encoding in API payloads.

Input → Output

URL Encoder input → Base64 Encoder output across 2 steps.
