Convert Images to Base64 Instantly
Base64 encoding lets you embed images directly in HTML, CSS, or JSON without a separate file request. This tool converts your image to a Base64 string and a ready-to-use data URI — entirely in your browser.
When to Use Base64 Images
- Embedding small icons or logos in CSS
background-image - Including images in email templates that need to be self-contained
- Storing image data in JSON or database text fields
- Reducing HTTP requests for tiny images (under ~10 KB)
Keep in Mind
Base64 encoding increases file size by roughly 33%. For large images, linking to a file is more efficient. Base64 works best for small assets under 10 KB.
