Resize Multiple Pictures At Once in One Click in Windows with Fast Image Resizer

Sometimes we probably need to resize multiple pictures. Fortunately, there are many free tools that can be used to resize images in batch. One of these programs that you should try is Fast Image Resizer which is developed by Adionsoft. It is a simple tool that you will probably find pretty useful when you need to process many photos at once. Supported image formats are JPG, BMP, GIF, PNG, TIFF and HD Photo (.wdp, .hdp) files.

If you want a straightforward application so you can get it done in no time, this one might suit your need. Users can either make use of the Send To menu or the Drag and Drop feature to process the images. I tried to resize 232 images at once, most of which are high resolution, and it managed to finish the task within around three minutes.

How to resize multiple pictures at a time

1. Download the installer and install the program. If you want to utilize the Send To menu in Windows explorer to send the images to the program, make sure the option is activated when installing the software.

  • Whenever you want to resize images using the previous resolution settings, you can just simply send the images to the application using the Send To menu.
