#2Seems to work but I was surprised to see the "Uploading" message. For me to trust it with secret files I'd at least want it to work locally with nothing being sent to the server.

#3'We currently use the AES encryption algorithm combined with strong password hashing to ensure your data is secure as possible.'
They don't mention cipher mode, hash algorithm, hash tuning parameters, or if they are even using authentication of some form alongside the encryption.
Complete transparency in terms of crypto ensures you aren't holding a steaming pile of shit if the service becomes popular and it is found that you were using ECB and SHA1.

#4Just so I'm not misunderstanding: we just have to take it on trust that the developer isn't holding onto the data we upload, right?

#5This would help me tremendously if it was an open source lib.

Even if it did it in-browser and didn't show you an upload message, you still need to trust the JavaScript that gets downloaded when you load the page. It could upload behind your back. Or, it could embed your password in the image, encrypted with a known key.
You MUST trust the software you feed your unencrypted data to. And if that softare is downloaded each time from the web, it's rather hard to do.

#7Some of the "common passwords" listed in the javascript are a hoot!
That said it looks like it does it all client-side (but I'm not 100% sure -- could we get a confirmation on that?)

#8So there are two way I can see how they did this encoding, either way they still store some data on their side. It would be useful as an offline app for sure.

#9steghide [1] has been around for more than a decade and can hide data in WAV files as well.

#10I won't trust such an online service.
A search for steganography on github lead to projects like darkjpeg that are open-source.
