Image to Base64 Encoder

About Image to Base64

Base64 encoding converts binary image data into a text string that can be embedded directly in HTML, CSS, or JSON files, eliminating the need for a separate image file. The encoded data is prefixed with a data URI scheme.

Common Uses

• Embed small icons in CSS to reduce HTTP requests
• Include images in JSON payloads or API requests
• Embed images in email templates
• Include images in single-file HTML documents

Note

Base64 encoding increases file size by approximately 33%. For large images, use external files and standard img src tags instead.
