How to reduce image size in batch ( Free Software )

Irfanview is free software that can decrease image size, color depth, format conversion (e.g., BMP to JPG), and many others. After I received my marriage pictures, I was shocked to see that size of each image was around 3 MB. Later, I learned it was taken from Nikon Camera and had a high resolution.

Now images with sizes like 4 MB are not helpful over the internet. Not only it takes time to upload, but also, viewing the same is slow. I had one more problem with more than 300 images. Now it isn’t very pleasant to do it individually. I wanted something which could do this job in a batch process.

Irfanview is a small-sized free download software that solved both problems without affecting my image quality.

The features of Irfan View are: –

  • Change Image Size by reducing resolution.
  • Batch Crop, Resize, and reduce color depth.
  • Set transparency.
  • Output in most common image formats.
  • You can even use Video files.
  • Batch Rename.
  • Customized Settings can be saved into a file. This allows you not to set things again and again. Just load the settings file and convert.
  • Insert Text into images.
  • Mix any number of images and output as one file.

  2. Awesome! Thanks! I also have this software and didn’t know it could do this. I used it to decrease the size of all my pictures so I could load them onto my iphone. FYI, for iphone users, the screen size is 800×600 pixels. I just decreased the size of my pics to this and decreased the quality to 75%. Shrank the size by about 10. Great!
    Keep up the good work
