Base64 usually adds about one third to the original file size. It is useful for small assets, but regular image files are often faster for large photos.
Frequently asked questions
What is an image data URL?
It is an image encoded as text with its MIME type, such as data:image/png;base64. It can be used directly in HTML or CSS.
Can I decode plain Base64?
Yes. If the data URL prefix is missing, choose the expected image type and the tool will add the correct prefix.
Does converting reduce image quality?
No. Base64 changes how the original bytes are represented, not the image pixels or quality.
Is my image uploaded?
No. Encoding, decoding and previews happen locally in your browser.
