With the help of the Image Resizer, you can resize a great number of images at the same time, for example if images are to large to send them per mail or if you want to save more images on a data medium than it is possible with your ones.
There are several possibilities to enlarge or shrink images: you can scale to a pixel size, percentage or according to the file size. When you scale to a pixel size, you can enter a size in pixels, the resulting image should have. If you resize percentage, you can, for instance, double or halve the size of images and if you scale according to a file size, the pictures are resized so that the new images have your desired file size.
In addition, there are lots of other options available, you can adjust if you want: For example, you can change the file format of the images, you can resize images only if they will be larger or smaller than the original ones, you can resize proportional or not and many other things explained on this pages. Furthermore, the Image Resizer supports 31 file formats. You can open images of these formats and you can save arbitrary images in one of these file formats.
If you wish more functions regarding image processing, you can also use our software Image Converter.

On this page, you can find a complete list of all functions of the Image Resizer, sorted by their occurence in the application. If you want to read a general introduction to the functionality of the tool, you should read the help section.
The main program is divided into the three steps "Select Images", "Choose Size" and "Save". These steps can be select directly through the buttons at the top of the window or you can use the button "Forward" in the upper right of the main window, with which you can go through the steps. In the last step, this button changes to "Save Images", so that you can resize and save all selected images according to the settings in a final step.
• Select Images: In this step, you can decide, which images should be resized.
• Select Images > Open Folder: Opens the dialog to select a folder, which will be searched for images. It is also possible to write or copy a folder into the box and click on the return key to add this folder.
• Select Images > Filter: Opens the filter dialog, in which you can set which file formats should be added from the folder and whether you want to search sub directories, too.
• Select Images > List: In this list, there are all files that should be processed. You can drag and drop files from arbitrary directories to this list and you can delete files from the list by using the DEL key. If you right click on the files in the list, other options will be shown.
• Select Images > Delete Selected: Deletes the selected images from the file list.
• Select Images > Delete All: Deletes the complete file list.
• Choose Size: Here you can adjust how the images should be enlarged or shrinked. Other settings can be found in the menu "Settings > Options". This menu can also be called with the button "More Options" on the size panels.
• Choose Size > Resize to Pixel Size: Here you can select one of the pre-defined sizes for your resizing. If you keep the proportions, the selected size can be understood as maximum size. If the proportions are not kept, the images will be scaled exactly to the selected size without careing about proportions.
• Choose Size > Resize to Custom Pixel Size: Here you can enter an arbitrary size for your images in pixels. Again, it is possible to keep proportions or not.
• Choose Size > Percentage Scale: With this option, you can enter a scaling factor in percent, so that you can, for example, halve (50 percent) or double (200 percent) the images. Of course, you can scale with proportions again. If both values are the same, you are always scaling proportional, but you can also enter different values, for example 50% width and 200% height to stretch the images.
• Choose Size > Factor/Ratio Scaling: Here you can type a factor with which the image will be scaled. You can use integers such as "2" ( images is scaled with factor 2), fractions such as "1/3" (image will be scaled with factor 0.33333...) or ratios such as "4:2" (image will be shrinked with factor 2).
• Choose Size > Resize to File Size: Here you can enter a file size, the new images should have. That means, the images will be scaled to a size in which they have nearly the desired size. Sometimes it is not possible to reach the exact file size.
• Save: In this step, you can select how to save the images will all saving settings.
• Save > Overwrite Original File: The new images will overwrite the old images. Attention! The old images can not be restored after overwriting them with the new ones.
• Save > Save as New File: The resized images will be saved as new images. It is possible to enter a folder, a file name and an arbitrary file format. In each box, you can also select <keep> to use the attributes of the old image. In addition, you can use some variables in the names, which are then replaced by their meaning. For instance, the file name %name%-new would use the old name in addition to the string "-new" at the end of the name. The following variables are available: %folder% (name of the old folder), %name% (name of the old file), %num% (number of the image in the list), %0num% (number with leading zeros), %abs% (absolute number of all images in the file list), %width% (width of the image) and %height% (height of the image). Of course you can also use more than one variables in the same file name.
• File > Open Images: With this function you can open single files with the open dialog and these files will be added to the file list.
• File > Open Folder with Images: With this function you can open a complete folder to add the images to the file list.
• File > Delete selected Images from List: Deletes all images from the list which are currently selected.
• File > Delete all Images from List: Deletes the full image list independent from selections, so that you can add new files.
• File > Convert and Save: This function is the same like the button "Save Images" in the main window. So, the images currently in the list will be resized and saved according to the saving options.
• File > Only rename Files: Opens the File Renamer, which is explained on the separate page File Renamer. With this tool, you can change the names of a number of files.
• File > Close: Exits the application.
• Settings > Options: Opens the options. These are explained in the section Options on this page.

This can be in landscape or portrait. If the option is disabled, the image will be scaled without this distinction. For example when scaling a 800 x 600 image to 400 x 300, the resulting image will be 400 x 300 in each case the original language is in landscape. If the original image is portrait (600 x 800) and the distinction is enabled, it will be scaled to 300 x 400, too. If the distinction is disabled, it will be scalled to 400 x 533.
• Process if Original is smaller/larger than Maximum Size: With this option enabled, the image will only be resized if the original image is smaller or larger than the maximum size. So it is possible to add some images and all images that are larger than the maximum size will be scaled down but the other images will not be scaled up.
• Resize Method: Here you can select the resize method which can be Bicubic, Bilinear or Nearest. Other methods result in other processing times and other image quality. It depends on what you want to do.
• Output Quality for the Formats JPEG, JNG, MNG and JPG2000: The output quality can be adjusted for this functions. A better quality results in a higher file size and vice versa. Again, it depends on what you want to do.
• Use Progressive-Function for the Formats JPEG, JNG and MNG: With this function, the progressive function is used for this file formats, so that the images can be displayed faster on the web.
