-- **URL safe**: Uses only characters that are safe for URLs and filenames
+- **Urlsafe**: Uses only characters that are safe for URLs and filenames
 - **No padding**: Removes trailing `=` characters for cleaner output
 - **String output**: Returns proper strings instead of bytes (unlike Python's standard library)
 - **Fast**: Based on Python stdlib, with constant-time padding restoration
