FAQ
How do I convert an image to Base64?
Drag and drop your image (PNG, JPG, GIF or WebP) into the tool: the Base64 string and data URI are generated instantly, ready to copy.
What is a data URI?
A data URI is a URL that embeds the image content encoded in Base64 (e.g. data:image/png;base64,...), usable directly in src attributes or CSS backgrounds.
Are my images uploaded to a server?
No. The conversion runs entirely in your browser; no image or data ever leaves your device.
Does Base64 increase file size?
Yes, Base64 encoding increases the data size by roughly 33%, so it's best reserved for small images such as icons and logos.
