Imagine a situation that you just come back from trip and your are very excited to share your enjoyment’s photos on Facebook or other social networking site. But when you try to upload these photos it take too long time, because these are high resolution images having large size which is unnecessary for posting on social networking sites.
So best way is to reduce quality and dimension of the images and then upload them. Also it is best way to save on your mobile because it will take less space.
For this there is two option.
1) Online web tools :
Now there are many online website like reduceimages.com, shrinkpictures.com etc. where you can upload your images, then select the parameter like pixel, image quality and you will get the reduced size image. But the disadvantage is you can shrink one image at a time.
These both software are free to download and easy to use. Here you can select many images at one time to compress. Also there are many options like quality, size of image and save type while compressing.
