Linux users who have the KDE desktop environment installed and are in need of a good utility for making their images more space efficient would do well to check out EasyImageSizer. The utility is also available for Windows, but as I only have Linux installed, all my experience with EasyImageSizer is with version 1.3, the most recent Linux version. EasyImageSizer is actually a Qt application, so while it fits in great with KDE, it also should blend in nicely with GTK-based environments such as xfce and GNOME.
When you first open EasyImageSizer, you have three types of “open file” dialogs available to you. You can open an image or images (by control-selecting what you want), you can open a folder of images, or a folder and all its subfolders. Once you have opened your images, you can show a small preview thumbnail, which is helpful if your images are similarly named, or are in a series.
EasyImageSizer has many options for tweaking your photos besides simply resizing them, as the name suggests.
The first set of tools is related to the image quality. You can change the quality on a sliding scale, or leave it alone if all you want to do is resize the image or use on of the program’s other features. You can also select a target file size for your image, which tells EasyImageSizer the maximum allowable size (in kilobytes), and lets it choose quality settings based on that.
Like choosing a quality settings, EasyImageSizer allows you to resize an image two different ways. You can change the size based on a percentage or by pixels. So if you want an image to be exactly 50 percent of the original, simply change the horizontal and vertical percentages to “50” and you’re through. If, on the other hand, you want to change a 1920×1080 image so that it’s only 720×405, you would just type those numbers into the “Size in Pixel” fields. You can – in either case – select options that keep the same dimensions, or stretch the image either horizontally or vertically. Finally, EasyImageSizer has a number of standard preset sizes which allow you to quickly modify a larger image to a standard size.
The next option is for renaming your images. EasyImageSizer can rename them using base text of your choosing (for example: birthday_party), and then add the date to it, as well as numbering the series, starting with a number of your choosing. Finally, you can use EasyImageSizer to add an overlay image to all your photos, for very basic watermarks.
When all your changes are set, you can have EasyImageSizer save the tweaked image as a copy, in a new directory (or old), or overwrite the old image. You can also save the image in a number of formats, which is useful for particular use cases where a specific format might be necessary.
To be honest, there’s nothing present in EasyImageSizer that isn’t in other photo resizing programs, but EasyImageSizer is very easy to use, seemed quite fast in my tests, and regardless of your environment, should blend in nicely. It was a small download (only requiring a couple extra Qt4 libraries on my Kubuntu system), and doesn’t seem to use a lot of memory. All in all, I’d say it’s a winner, and well worth trying.
