Base64 vs URL Encoding: When to Use Each
By ZonoTools5 min read
Core difference in one sentence
Base64 converts binary or text data into an ASCII-safe format, while URL encoding escapes reserved URL characters.
They solve different transport and compatibility problems, so using the wrong one can break APIs.
Practical examples from web apps
Use URL encoding for query params and form links, especially with spaces, symbols, or non-Latin characters.
Use Base64 when embedding small assets or handling binary-like payloads in text-only channels.
