Somehow, FS re-sized images look better than Irfanview. A lot of my work gets posted on Facebook (not my choice!) and we all know how FB can maul an image. I used to use Irfanview for bulk re-sizing but have now switched to FS as I think it does a better job. I don't carry out edits and resizing in Faststone - I use ACR and Photoshop for that.

It shouldn't happen but, evidently, they do. I see your point about different programs displaying different renditions. Play with them and choose the one you like best. On my version 5.3 there are 2 Filter options: Lanczos and Lanczos2. If you turn it on (checked) another option appears called 'Filter'. In FastStone, under 'Settings/Settings/Viewer' there is a 'Smooth' check box option.

Some are biased for quality and add sharpening.įaststone has one of the best resizing and sharpening methods.

Some programs are biased for speed and do no special sharpening. The amount of 'sharpening' that occurs in that manipulation will vary from program to program. Any program that resizes an image for display on a monitor must manipulate the pixels.
