How to use Image to Base64
Encode an image as a data URL that can be used in small HTML or CSS experiments. The tool reads the original file bytes rather than re-compressing the image. A data URL includes both its MIME type and Base64 payload, so copy the whole result when you need an embeddable source.

Select a local image
Choose the image file you want to encode.
02
Create the data URL
Run the tool to encode the file contents as Base64 with an image MIME prefix.
03
Copy the complete result
Copy the data URL or save the text output for your project.
COMMON QUESTIONS
Image to Base64: useful answers
Does Base64 make an image smaller?
No. Base64 usually adds about one third to the byte count, plus the data URL prefix. Use ordinary image files for larger assets.
Does encoding change the original image quality?
No. This tool encodes the selected file bytes. It does not resize or re-compress the image.
