Use this free Base64 encoder to convert plain text into Base64 format instantly. It is useful for API work, basic data transport, quick header preparation, test payloads, and checking how a string looks after Base64 encoding.
Base64 Encoder is built for development, debugging, formatting, and quick technical checks directly in the browser.
Base64 encoding converts data into an ASCII text format using a limited character set.
No. Base64 is encoding, not encryption.
You can encode plain text, snippets, tokens, or other text-based content.
Yes. It works online without signup or installation.
