Upload an image to encode to Base64
Encoding a single local image into a Base64 string to paste into one specific place, a JSON config's icon field, an inline data attribute, doesn't call for a bidirectional tool built around switching between encoding and decoding, especially when the image never needs to leave the local machine at any point in the process. This tool converts any image into a Base64 data URL entirely in the browser, reading the file locally with no upload step involved, focused on the single encode direction rather than a two-way conversion tool.
