Convert an image into a Base64 data URI for inline embedding.
About the Image to Base64
The Image to Base64 tool converts a picture into a Base64 data URI you can drop straight into HTML or CSS, embedding the image in the code itself. It runs in your browser, so the file is never uploaded, and it is handy for small icons or email-safe images.
Frequently asked questions
It suits very small images like icons, where avoiding an extra network request is worth it. For larger images the encoded text becomes bulky and slows the page, so a normal image file is better.
Base64 represents binary data using only text characters, which adds roughly a third to the size. That overhead is why it only makes sense for small assets.
