About Base64 Encoder

Encode text or uploaded files to Base64 and optionally include a data URL prefix. This online utility is designed for a focused task, with clear status messages and browser-friendly fallbacks. Local-file work stays in the browser unless the page clearly identifies a network-backed lookup; URL mode contacts the source you provide and remains subject to that source's CORS policy.
