About Base64 Converter
Base64 is everywhere — in email attachments, JWT tokens, data URLs, API responses, and embedded images. This converter lets you encode any text or file to Base64 or decode it back to plain text in one click. No installations, no sign-ups — just paste and convert.
Developers use Base64 encoding when they need to transmit binary data over text-only channels like JSON APIs, or embed images directly in HTML and CSS as data URIs. Use this tool to decode encoded payloads when debugging, convert files for API use, or verify what's inside a Base64 string you received.
