Text conversion workflow
A straightforward Base64 check for payloads, test data, and quick debugging.
Base64 is everywhere in everyday development work: small test payloads, data URLs, tokens, sample JSON, email bodies, and API troubleshooting. This tool gives me a fast place to encode or decode text without opening a heavier editor or reaching for a command line when I am already working in the browser.
The page is intentionally simple because Base64 should not be mysterious. Paste the value, convert it, and check whether the output is readable text or just binary data represented as text. That quick feedback is often enough to spot a bad copy, double encoding, missing padding, or the wrong input entirely.
Do not paste secrets, credentials, private keys, or production tokens into public browser utilities. Base64 is encoding, not encryption, and anyone with the string can decode it.
