What is Base64 File Encoder?
A file-to-base64 encoder that converts any file into a base64-encoded text string. Useful for embedding files in JSON, HTML, CSS, or transferring binary data through text-only channels.
How to use
- Upload or drag-and-drop any file (images, documents, audio, etc.) into the encoder.
- View the generated base64 string along with the file size, MIME type, and data URI format.
- Copy the base64 string or data URI to your clipboard, or download it as a text file.
Result
A developer needs to embed a small icon directly in a CSS stylesheet. They upload a 2KB favicon.png and copy the generated data URI to use as a background-image value.
