As I stated, I don’t use these types of tools. Just about every alternative people have mentioned has been on my list of image-editing applications. As #35, who said that, mentioned, Photoscape has a simple-to use batch editor, and a video showing its use on their website. I did find a batch add-on for Paint.NET, but it’s not well-integrated. True batch resizers are generally easier to use and have options that image-editing applications, even those which allow batch operations, may not have. For example, most support settings presets, some have options to not upscale images which are smaller than the resize dimensions, and to output files which are guaranteed to be less than or equal to a maximum filesize. For example, I use Quick Photo Resizer because although it has few features, it’s very easy to use, and at the time I bought it (at a discount), it was the only app I could find that actually honored the maximum file size constraint (necessary for my photo host). JpegSizer is another commercial product that’s focused on resizing, but has a lot of options and presets. People who haven’t tried them shouldn’t dismiss them because they’re commercial products, they may have features or ease-of-use which the freeware products don’t have.

I find the complaints about the embedded static ad to be silly (it doesn’t meet the definition of adware). A lot of programs have ads in their help files, some have ads in the products themselves, even if you pay for them. As I’ve stated before, companies are generally losing some potential revenue by posting their wares here on GOTD, so you’re going to continue to see attempts to get you to purchase better versions.

Regarding the question of having to enter two values, even if aspect ratio is desired to be maintained when resizing….

I haven’t installed BIR, but I’ll hazard a guess as to why this might be a useful (and necessary) feature. Both BIR and Image Badger are designed to be primarily BATCH Image re-sizing tools. I also found it less than intuitive when I first attempted to resize a single image in Image Badger. I agree that, when maintaining aspect ratio, most image editing software only requires one dimension to be input, and it’s very user-friendly to see the other dimension automatically calculated in proportion, and input on-the-fly.

But this obviously is not a possibility, if you were wanting to re-size a batch of diversely sized images. Using Image Badger as an example…If original aspect ratio is selected to be maintained when re-sizing, Image Badger will ask for the input of (one or both) Max Width and Max Height values.

Let’s say your intention was to batch process a collection of your photographs, so that they might all fit nicely, for printing four on a page, each within 400×300 constraints. Entering 400 and 300 as maximum values, will serve to re-size all diversely shaped images so that they are as large as can be permitted, within the bounds of your constraints. Sometimes, it will be the Maximum Height value that is crucial when re-sizing, whilst with a different shaped original, it may be the Maximum Width which determines the size.

FWIW, I was basically carping about the design and seemingly excess buttonpushing. Pointing out the need to click both width and height to enable proportional sizing was my oblique comparison to Photoshop’s and MSOffice Picture Manager’s methodologies. (they employ different sets of steps to arrive at the same proportional result) Admittedly, it may be just my familiarity with those applications that make them seem less cumbersome. I realize that Batch Image Resizer’s dual buttons allow one to choose which measure to constrain, but my obtuseness prevents me from appreciating a benefit from doing it that way.

PS: Image | Image size and enter width or height and the other automatically changes (I usually keep Constrain Prop enabled)

MS OPMgr: Edit | % of Orig Size (and watch as measurements change between orig size and new size)

IrfanView: Image | Resize | (with default Preserve Aspect Ratio)

Jeez, I completely forgot about Faststone and it’s sitting on my desktop for easy access. So many programs, so little time.

Keep it up, GAOTD!

What I think is a critical omission is the ability to change image resolution without re-sampling… Say for example you have a picture from your digital camera that you want to print. On screen it may be huge, with a screen resolution of 72 or 96 (MAC or PC respectively). TO make a print you want a resolution of 300 – 600 dpi – very basically you squeeze the pixels closer together the way your printer likes it. Batch Image Resizer can’t do that… you can create new pixels out of thin air, &/or you can resize your image smaller, throwing out a good many original pixels, but you can’t just shift them around, maintaining the original quality.

With that glaring oversight (so easy to implement), the developer can rest assured their ads for the more expensive version will be ignored – ‘least by me. But I’m sure there will be times it’s quicker to fire up and use than many of the alternatives, where you often have to drill down through a couple of menus and set up the batch operation.

One place not to use a program like this is with anything video unless it’s animation, as at least one comment has talked about [& why I’m tacking this on here]. Aspect ratios get really tricky with non-square pixels, & the color space conversions can really muck up quality.
