There is a hook for image resize which makes a plugin possible.

And more from Julian.

We don't have any client-side image editing tools at the moment

As @nhl-pl says, there are some hooks that you may want to utilise. The image resize hook specifically is only called whenever resizeImage is called in NodeBB, which is mainly for user profile updates. If you're thinking of a more generic resizing (i.e. applicable to all locally uploaded images), then we might have to create a static hook to be fired when an image is finished uploading.

It's worth mentioning there are some Node.js modules which can be used as dependencies.

The fastest Node.js module for resizing JPEG, PNG, WebP and TIFF images.

And here an example how it can be used.

Alternatively, if you don't wish to add dependencies, you can use jimp, which is already installed in NodeBB:

var jimp = module.parent.require('jimp');

@julian don't do this or recommend doing this. Add the package to your deps and require it normally. npm can decide to install it or not.

Never rely on other modules' deps to be stable.

Need this plugin badly because for most of our post, we have screenshot of images.

Possible to have a plugin that can resize and compress images at the same time?

Compress images: https://tinypng.com/ has a nodejs package
