I used IrfanView to resize one set, and I decided to try FastStone (portable version 3.7) to resize the other. I made two duplicate copy sets from the originals. Some were larger than 1280 pixels wide some were smaller. (Later, Softpedia’s reply to my inquiry assured me that this version had been removed from the site, and that the newer beta version was virus-free.)Īs indicated in the other post, I was working with a set of 5,590 JPGs. But when I tried to download it, my AVG antivirus software warned me (consistent with some older notices) that it contained MalSign.OpenCandy.7AF. I was interested in comparing IrfanView against an entirely different tool, and anyway AlternativeTo users vastly preferred RIOT (with strong warnings to be careful not to install its optional adware during installation). I was inclined to try RIOT. AlternativeTo named XnConvert as another possibility, but that appeared to be an XnView project, the latter controversial for allegedly stealing from IrfanView. A search led to a Raymond list naming, among others, RIOT (Radical Image Optimization Tool) (4.4 stars from 63 raters at Softpedia) and FastStone Photo Resizer (4.4 stars from 32 raters at Softpedia). I wasn’t sure which other tool to use for photo resizing. I had previously used IrfanView to achieve that sort of resizing, but now I wanted to compare IrfanView against another resizing program. My starting question was whether I could get decent results by downsizing the larger images to be no more than 1280 pixels wide. This size reduction was possible through setting FastStone to JPG quality setting 90, checking the option to “Use JPEG quality from the original file if possible,” and using other settings (mostly defaults) described below.
Briefly, the following discussion comes around to the conclusion that, for a set of 5,590 JPGs filling 5.6GB of disk space, FastStone was effective in achieving an 80% reduction in total file size (after treatment: _GB) without any appreciable loss of quality.
This post explores the use of IrfanView and FastStone Photo Resizer to reduce the size of those JPGs without losing quality. Space was a concern because I was trying to decide whether it would work to combine all these JPGs into a single PDF, and unfortunately the PDF-creation software was crashing because the images were too many, too large, and/or too complex. As described in another post, I was looking for ways to archive thousands of unimportant images in a space-saving way, without simply discarding them.
