About Image to Base64
Load an image and copy it in whichever inline form you need: the full data URL, the raw Base64 payload, a CSS background-image declaration, or a complete <img> tag with the real width and height filled in.
Inlining avoids an extra network request, which is handy for small icons in emails, single-file HTML documents, and quick prototypes.
Common uses
- Embed a small logo directly in an HTML email
- Inline icons into a single-file demo page
- Paste an image into a CSS-only environment
Limitations
- Base64 is about 33% larger than the binary file, and large inline images slow pages down — the tool warns above 1 MB.
