I've done similar with images for the fun of it. The simplest solution that I recall finding was to base64 the file/data, then turn to hex, then use those hex data to create pixels in RGB. I would line them up top-left to bottom-right.

Probably not the most efficient but easy and fast and the resulting images would look... interesting. For large files, the decoding would be difficult mostly just due to reading the image of so many pixels into memory. So, that's when I began fixing the image size to a smaller size and having multiple images that I would later convert to 60fps video. I could then use ffmpeg to convert images to frames and frames back to images.

I had no practical use for this but, was a fun project on a rainy afternoon.
