SHA-1 collider: Make your own colliding PDFs

This overstates the difficulty of creating a JPEG. If you have an image editor on hand that isn't MS Paint (or you're using macOS, which has Preview), you merely need to export a JPEG and choose a low quality setting.

For a Windows user with no decent image editor or viewer installed, though, it could certainly be a hassle.

None of the things I listed are difficult. They just require the right tool and know how. For someone like me with Xubuntu, I had neither the tools nor know how for creating small jpegs. I didn't fell like wasting 30 minutes researching and I didn't feel like walking over to a different computer that has MSPaint.
