Is this black magic? Possibly. Is it awesome? Definitely.

Great job, this is a really neat tool that I can see myself using to quickly send certain files to others in a somewhat secret way (mostly just for fun though).

If anyone wants to unscramble this super secret message, you’ll have a surprise.

I've tried a few different file types (PDF, WAV, EPUB, OBJ) and sizes, but I always get the same result: entirely transparent images. The dimensions do seem to vary, though. This happens whether I run the tool in Chrome or Firefox (both in OSX), and regardless of where I try to view the image.

Wish I could get it to work, it's a fun idea!

This is an interesting idea, but I ran into a couple issues while trying it out:

• the drag-and-drop file interface on web works on chrome, but not firefox; I'd recommend using a file input tag so you can click to open a system dialog in addition to natively supporting drag-and-drop
• the generated pngs seem to be slightly corrupted; I was able to open them in a browser, but another image viewer gave the error "libpng: IDAT: Extra compressed data; libpng: Not enough image data"
