A Base64 data URL embeds file content directly in HTML or CSS as a text string, eliminating the need for a separate HTTP request. This is most useful for small images like icons or logos where the overhead of an additional network request outweighs the ~33% size increase from Base64 encoding.

What can I do with the Base64 output?
You can embed the image directly in HTML using an img src attribute, in CSS as a background-image url(), or in JSON payloads where binary data is not accepted.
Does Base64 increase the file size?
Base64 encoding increases the data size by approximately 33% compared to the original binary file.
Is my image uploaded to a server?
The image is read and encoded entirely in your browser using the FileReader API. No image data is transmitted anywhere.
What image formats are supported?
Any image format the browser can read - PNG, JPEG, WebP, GIF, SVG, and others - can be converted to Base64.
Is there a file size limit?
There is no hard limit, but very large images produce very long Base64 strings that may be slow to copy or use in certain contexts. For large images, consider compressing first.
