Upload any image file and translate it into a standard Base64 data URL string. Copy code segments directly for inline CSS stylesheets, JSON structures, or HTML markup configurations.
Common questions
What is a Base64 data URL?
It is a standard encoding format that embeds image binary data directly into a text string, letting you render images inline without separate HTTP fetch calls.
Is there a limit to image file size?
Encoding very large files might create extremely long strings that slow down text editors. We recommend using it for icons and smaller web graphics.
