This tool is helpful for developers, API testers, and SEO professionals working with encoded payloads or data transmission. If you’re extracting encoded values from text, try the Extract Between tool as well.
Why use Base64 encoding?
Base64 ensures data remains intact when transferred through systems that only reliably handle text content, such as URLs, headers, or JSON payloads.
