A LITTLE BACKGROUND
Image to Base64: the practical context.
Encode a local image as a Base64 data URL for a small embedded asset. Create a data URL when a small icon or prototype needs to travel inside a single file. The output includes the media type and can be copied as text.
Put it to work.
Choose a still image that you are entitled to use, then run the sample or your own file through the settings. Base64 increases size by roughly one third before transport compression. It is not image optimisation and is usually unsuitable for large website photographs. Input is limited to 5 MB. Use the visible preview to check edges, lettering and the subject rather than judging the result from the filename alone.
What to check next.
For a website asset, connect the image decision with its actual display size and purpose. Keep a high-quality source separately. A transformation can remove camera metadata or alter transparency, and browser colour handling can differ from a professional colour-managed workflow. The downloaded copy should be inspected before it becomes the only version you retain.
