How to Convert an Image to Base64
Create a Base64 data URL from a small image and know when not to use one.
Use Base64 for small assets
Base64 image data is useful for tiny icons, quick prototypes, email snippets, and API fields that expect a text payload. It is usually not a good fit for large photos.
Choose data URL or raw Base64
A full data URL includes the MIME type, such as data:image/png;base64. Raw Base64 is only the encoded payload. Use the version your HTML, CSS, email tool, or API expects.
Watch output size
Base64 text is larger than the original binary file. If the output is long, compress or resize the image first, or link to a normal image file instead.
