I have a set of images (more than 1000) that are low in quality. (blurry when zoomed) How can I enhance all of them at once , Is there a software for that ? or can I do it with a programming language ?

Edit

Im using windows and I want to reduce the blur by sharpening images

Two actual questions here:

  • Can I enhance an image that is blurry when zoomed?

    Not really. The reason this happens is that the image has a relatively low resolution compared to how you are trying to use it. While you can apply a sharpening filter, you cannot add detail that doesn't exist.

  • Can I enhance lots of images at once?

    Yes, quite easily and there are many tools to do this though you don't specify what Operating System you are using so hard to be specific.

    One tool that works across platforms is ImageMagick but there are many others, some have specific functions such as using JHead or exiftool to read and change image metadata.

    Irfanview is another tool that may do the job (Windows only)

    There is a little more information in the answers to this question.

    ImageMagick will do the job, just don't expect miracles. – Julian Knight Dec 10 '16 at 20:49
