About URL & Base64 Converter
This dual-purpose Converter handles URL encode and Base64 operations in one interface. It allows you to sanitize strings for safe transport via HTTP or encode binary data into text formats, covering the most common encoding tasks for web development.
Fix broken links and data transmission errors. URL decode logic restores readable text from percent-encoded strings, while Base64 is essential for embedding images or handling JWT segments. This tool ensures your data remains intact across different systems.
Choose your mode: Encoder or Decoder. Paste your text. The output updates instantly. It properly handles UTF-8 characters to prevent encoding glitches with emojis or non-Latin scripts.
Under the Hood
Encoding relies on the standard `encodeURIComponent` (URL) and `btoa`/`atob` (Base64) web APIs. For Base64, we handle Unicode limits by UTF-8 encoding the string before conversion, preventing "The string to be encoded contains characters outside of the Latin1 range" errors. This ensures proper handling of emojis and multi-byte characters.
