How this tool handles your input
Encoding reads a local raster file as Base64. Decoding accepts Base64 raster data with an optional matching data-URL prefix and verifies it as an image.
SVG, HTML and arbitrary files are rejected. A 10 MiB technical budget applies; Base64 increases byte length by roughly one third.
Example: A PNG data URL begins data:image/png;base64,
