Base64 encoding translates binary image data into ASCII character strings. Embedding images as Base64 strings directly inside HTML or CSS reduces HTTP requests for tiny icons and graphics.
Frequently asked questions
Is my image uploaded to an external server?
No, all image encodings are processed locally inside your web browser using HTML5 FileReader API.
What image formats are supported?
PNG, JPEG, WebP, and SVG files are fully supported.
Should I convert large photos to Base64?
It is recommended to encode only small graphics or icons since Base64 increases data size by roughly 33%.
