You rebuild the AC coefficients in each DCT block whilst keeping the same DC. So basically decoding a couple of layers but not the entire image.

Or, just use one of the bajillion apps and libraries that implement it already:

There's a lot of interesting stuff that can be done in the frequency domain without a full decode,

there's a tool in there echinopsis is already very familiar with
