How to reduce image size in batch ( Free Software )

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

Now images with sizes like 4 MB are not useful over internet Not only it takes time to upload but also viewing the same is slow. I had one more problem that more than 300 images, now its very annoying to do it one by one. I wanted something which can do this job in a batch process.

Irfanview is small sized ( 1.1 MB only) free download software which was able to solve both of my problems with any noticeable affect on 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 together and output as one file.

Here are some images which will give you a better idea.

  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
