Some solutions not mentioned in the other answers:

For browser

jpeg-js

Similar to jpgjs mentioned by @PaulMilham, but with additional features and a nicer API (imo).

For NodeJS/Electron

sharp

General purpose image-processing library for NodeJS, with functionality to both read and write jpeg, png, etc. images (as files, or just in memory).

Since my program is in Electron, I ended up using sharp, as jpeg-js mentioned it as a more performant alternative (due to its core being written in native code).
