Encode and decode Base64 locally
Convert text to Base64 and back instantly. Everything runs in your browser, so your data is never uploaded anywhere. Useful for inspecting encoded payloads, headers and config values.
Frequently asked questions
Is my data uploaded?
No. Encoding and decoding happen entirely in your browser.
Is Base64 encryption?
No. Base64 is an encoding, not encryption. Anyone can decode it, so never treat it as a way to hide secrets.
