    I have tried to resize at 1024 px longest side and my images look rough.

    Can someone please let me know a quick way to do this.

    240kb does not seem like a lot.

    I have a preset saved, I did not use the forum one, that does 1024 on the long edge, resizes to 243k and 240 pixels per inch.

    @Roger S provided the fastest way, but it is not the best. I use Photoshop many others here use Lightroom. Both have excellent facilities for reducing the size of an image.

    Yes, when reducing an image to 240k image quality will take a hit. It has to, you just reduced the resolution by orders of magnitude. You can exercise some control of the amount of damage by how you edit the image and how you resize it. For example, eliminating or reducing the amount of sharpening and/or sharpening only after the image was resized to the correct size can help significantly. Also, the method of interpolation (resizing) can play a role. For example, Bicubic (smooth gradients) can make a resized image less "rough" while Bicubic Sharper (reduction) can enhance existing sharpening - and you can play these against each other in a reduction process. The quality of the reduced image also depends on the image, the greater the number of edges or points of contrast the more "damage" the image will take in the resizing - images having a lot of smooth surfaces fare much better.

    The OP did ask how to do it in Lightroom. There is no control over any of that in LR.

    This here is what I have my export preset set to, and I find that it doesn't cause any problems with image quality; just make sure you've got your noise reduction and sharpening applied correctly before you go to export as you could end up with images that are over-sharpened and displaying artefacts after the export process has completed.

    Yes, I have very limited experience using Lightroom. Though it has fewer options it has an excellent auto sharpening capability built-in but if you are having a problem downsizing without significant degradation you can still eliminate any watermarks, set the input sharpening to 0, set your output sharpening to low, and if you want to increase the quality (decrease the compression) of the image and the file size is a problem then set to a smaller image size. Sometimes it is better to have a smaller image with higher image quality.

    Sharpening can double the file size of a high edge frequency image, so sharpening technique would be the first place I would look to reduce file size without over compressing.

    Me. I resize mine in Photoshop.
    But think I will try resizing in Lightroom one of the days.

    I've often seen this graph in Lightroom but I cannot for the life of me fathom it out. OK, so I'm a dummy but it means nothing to me. I'm quite content to make my masterpieces as I see fit and my images are pretty good for presentation or saving.
