Error: unknown JPEG marker 0

Hi guys

I'm getting this error when trying to decode this file. I've attached the file.

The stack trace is as follows:

Error: unknown JPEG marker 0

The jpeg opens fine in:

• Windows 10 Photos
• Microsoft Paint
• Paint.NET
• IE11
• Google Chrome

But I get the following error trying to open the file in Photoshop CS6 (this old version is more sensitive to file issues):

What do you guys think?

Thanks for filing @googleoryx! It looks like a malformed JPEG. Given the current resourcing, this project can't make the same extensive recovery attempts that some other popular decoders can. If it turns out that this a very popular camera and encoder always produces files like this (such as the situation in #82), then we'd happily accept a PR for a workaround.

Hey there! Having the same issue here, but with JPEG music album images. Is there a way of "sanitizing" said images beforehand so that jpeg-js is happy with them?

Yes, but doing so mostly requires the same level of effort as decoding the JPEG to begin with.

If you are getting images from a popular encoder that always produces files like this, sending examples along with repro steps is the best path to getting a PR for a workaround :)

In my case, I work with unpredictably encoded JPG images, since they're from the Internet itself. Sadly I cannot send a sample and be done with it, as it might just really be corrupted and I wouldn't ever know
