Base64 Converter: private online developer utility
Base64 Converter helps decode opaque strings and encode text payloads used in APIs, headers, test data, and configuration files.
When to use it
- - Convert encoded text used in URLs, headers, forms, and API payloads.
- - Check whether copied values were escaped or double-encoded.
- - Prepare safe text for scripts, docs, and test fixtures.
Common input issues
- - Pasted input includes invisible whitespace or smart punctuation.
- - The source data is valid in one format but invalid in the target format.
- - A copied value includes surrounding quotes, shell escaping, or truncated content.
