The Image to Base64 Encoder converts an image into a Base64 data URI — a text string you can embed directly in CSS (background-image) or HTML (img src) so the image loads without a separate request. It runs in your browser, so your image is never uploaded.

Frequently asked questions

When should I use a Base64 image?+

Inlining works best for small, frequently used images like icons and logos, where saving a network request outweighs the ~33% size increase Base64 adds.

Why is the Base64 bigger than the file?+

Base64 encoding increases size by about 33%, because it represents binary data using only text characters. For large images this trade-off is usually not worth it.

Is my image uploaded?+

No. Encoding happens entirely in your browser, so your image stays on your device.

Is it free?+

Yes. It is completely free, with no sign-up and no watermark.
