I make up simple images for my blog and wonder if I could do them a better way.

I currently resize the image down to 1200px wide (my default size for the blog) and then add mostly text layers (headings, legends, logo etc.).

Then I save it for web using about 50% (RIOT in paint.net).

Would I get better results working on the full sized image and re-sizing at the end?
Thanks in anticipation...

If you know the final output size—work at that size.

If there's a possibility you will be using the image at different sizes then yes, work at a larger size, it will give you more flexibility, as Alex Fregon says. But if the image is going to be used at one specific size, work at that size.

If you work at a larger scale then shrink the image after exporting, you're resampling the text and logo and anything else you've added to the image—unnecessarily. You're likely to get artefacts or unwanted [anti-]aliasing.

An example:

This Image was created at the correct size:



This Image was created at a larger size then reduced in size later:



Notice the halo around the text and anti-aliasing. If we compare the images it is a lot more noticeable:



Another reason to work at your final size is avoiding unrealistic expectations. You're working at 3x your final output size, you finish your edits, export at a different size and wonder why your image doesn't look as good as it did. You then spend just as long trying to get you final image looking as sharp as it did 3 times bigger. You're just adding an unnecessary step.

It probably depends on the type of image - can you provide an example?

As a general rule, you're best off working at the highest resolution possible, as this gives you the most versatility when it comes to exporting. Say, for some reason you need to export your image larger than 1200px wide, scaling it up may cause your background image to become pixelated.
