[Guide] Freeware Irfanview Graphics app resizing screen shots
Old 01-02-2006, 02:06 PM   #1 (permalink)

I thought i'd elaborate on this to show you how much of a reduction you can get in size of the final screen shot.
Download www.irfanview.com and plugins...

prnt-scr -> open irfanview -> ctrl-v to paste image -> use mouse to highlight only area you want to show -> ctrl-Y to crop that area -> ctrl-R to resize it to 450-575pixels for forums -> save as -> jpeg -> options set at 65-75% quality
I used 65% jpeg quality on all below screen shots.

Full Desktop:
* prnt scr -> paste into irfanview -> jpeg 65% quality -> save as = 191kb

* print scr -> paste into irfanview -> jpeg 65% quality -> cropped to only info needed INCLUDES taskbar/clock -> save as = 182kb

* print scr -> paste into irfanview -> jpeg 65% quality -> cropped to only info needed crop away taskbar/clock -> save as = 160kb

* print scr -> paste into irfanview -> jpeg 65% quality -> cropped to only info needed crop away taskbar/clock -> resized smaller to legible font size (CTRL+R) -> save as = 108kb


3x CPUZ screenies + A64Tweaker:

* prnt scr -> paste into irfanview -> jpeg 65% quality -> save as = 124kb

* prnt scr -> paste into irfanview -> jpeg 65% quality -> cropped to only info needed showing -> save as = 111kb

* prnt scr -> paste into irfanview -> jpeg 65% quality -> cropped to only info needed showing -> resized (CTRL+R) -> save as = 72kb


For resizing (CTRL+R) ensure preserve aspect ratio is checked:

An update, discovered you can save a further 40-50% reduction in screenshot size if you use Irfanview to convert to greyscale BEFORE you save an non-resized screen capture to PNG format with PNGOUT enabled at compression level 9.

These screenshots with PNG format at compression level 9 were around 36-60KB in size but now check out the image sizes!
