Resize Listing Photos with IrfanView

You may have received large photos and need to resize them in order to properly upload the photos onto your listing. Maybe you have an older computer, and trying to upload the photos your photographer provided is taking too long. Whatever the reason, you may want to consider resizing your images so that they show up clearly on your listings.

To resize photos, we recommend using a free program called IrfanView. IrfanView is a free photo viewing and editing tool that can be used to manage and edit your photo albums. The program is easy to use and has minimal set up requirements. For help installing IrfanView, please visit our Download and Install IrfanView page.

Once you have IrfanView installed, there are a couple ways to go about resizing your photos. You can resize photos individually or do a Batch Conversion to resize all your photos at once.

This page only provides instructions for how to resize your photos. Answers to other questions you may have can be found on our Photo Upload FAQ.

Resizing Individual Photos

The instructions provided in this section will show you how to resize an individual photo. You will have to repeat these steps for each image that you want to resize. A set of instructions for batch resize is available in the next section lower on the page.

  1. Open the IrfanView program.
  2. From inside IrfanView, click File then click Open. A navigation window will appear. You can also press the letter ‘O’ to bring up the same navigation window.
  3. Select the image that you want to resize, then click Open on the right-side of the navigation window (outlined in the 2nd image to the right).
  4. The photo will appear on your screen. You may notice that your window stretches out to fit the entire image. IrfanView will try to fit as much of the photo as it can display on your screen.
  5. Once the Photo is showing on your screen, click Image at the top of the program. On the resulting menu, click Resize/Resample to bring up the Resize/Resample image window.
  6. The 4th image to the right shows the Resize/Resample image window.The section on the upper-left displays size information about your photo. The Current Size shows the current pixel size of your photo. The New Size displays what the new dimensions will be after resizing the photo.

    Our example uses the Set new size as percentage of original option. This option is recommended because it is the easiest to use. The percentage represents the size of your photo compared to the original. The settings in the image are set to reduce the photo to 25% of it’s original size. Use the New Size display to help determine whether your photo will have an acceptable size. Typically, you will want to aim for dimensions that are less than 1000×1000 pixels.

    It is highly recommended that the Preserve aspect ratio (proportional) option is also checked. It is already checked by default, but please double-check this option. It will help to ensure that your photo does not get stretched or distorted during the resizing process.

  7. When you are satisfied with your settings, click OK at the bottom of the window to confirm the new size.
  8. Once your image has been resized, you will need to Save the resized image. Click File, then click Save to replace the existing photo with the resized version. Repeat this process for each individual image that you want to resize.

Resize Multiple Photos

IrfanView has a batch resize feature that allows you to resize an entire set of photos. This option works best if all the photos are of a similar size. Typically, if a photographer was hired to take photos, the resulting images are all of a similarly large size. Prior to starting the batch resize steps, please take the time to find the current pixel size of your images. This will make it easier to determine how much the photos should be reduced in size.

  1. Open the IrfanView program.
  2. From inside IrfanView, click File then click Batch Conversion/Rename. You can also press the letter ‘B’ to bring up the same window. The Batch Conversion/Rename window is displayed as the 2nd image on the right.
  3. Use the navigation section on the upper right-hand side of this window to select the photos that you want to resize. Once you have chosen the photos, click Add in the section below. If you are resizing an entire folder, clicking Add All will add all the photos currently inside the folder, regardless of which items you have selected.
  4. On the upper left-hand side of the Batch Conversion/Rename window, make sure you have Batch Conversion selected. We will not be renaming any files.
  5. Under the Batch conversion settings section, select your Output format. This setting determines the type of image file that is to be created. Typically, the .JPG or .PNG formats are recommended.Also under the Batch conversion settings section, check the Use advanced options (for bulk resize…) setting. This setting needs to be checked, otherwise you won’t be able to access the settings window.
  6. Click Advanced. This will open a settings window, which is displayed in 3rd image on the right.
  7. As displayed in the 3rd image to the right, make sure to check the RESIZE box. This tells IrfanView that you want to Resize your images (as opposed to Crop or Change Color Depth).
  8. Below the RESIZE section, select the Set new size as percentage of original option. Percentages are used because it will spare you from having to figure out the exact pixel size that you need. The settings in the image are set to 50%. This will reduce all selected images to half of their original size. If you aren’t sure what percentage to use, find your photo’s current pixel size and go from there. Typically, you will want to aim for a size below 1000×1000 pixels.
  9. Make sure that the Preserve aspect ratio (proportional) option is checked. This option will ensure that your photos do not become stretched or distorted after being resized. The Use Resample function (better Quality) option may also help to maintain image quality on your photo, but it is not required.
  10. Click OK on the lower right-hand side of the window to return to the Batch Conversion/Rename window.
  11. The Output directory for result files section allows you to choose where the resized images will be placed. If you click the Use current (‘look in’) directory button, IrfanView will place the resized photos in a new folder with the original photos. You can also choose your own folder by clicking the Browse button in this section. A window appears that lets to select your desired folder.
  12. Once you have your Output folder selected, click the Start Batch button on the lower left-side of the page. You will see a screen appear that displays the progress of your batch resize. The resizing process is usually pretty quick, even on slower computers. Once it is complete, click the Exit Batch button on the lower right-hand corner to end the batch resize session.
  13. At this point, you can repeat the process if you have more images to resize. Your resized images will appear in the folder that you selected in Step# 11.
