[Gimp-user] File size reduction

["Derek Mortimer" <mdjs aaa co uk>]

Hello,

 

My name is Derek Mortimer.

 

I am looking for an open source application to reduce the number of pixels, thus reducing the number of kilobytes or megabytes, in a normal picture file, jpeg, etc.

 

In Photoshop, the process is called downsampling.  I have looked at the documentation for GIMP and sampling does not seem to be the correct term for the requisite process.  Nor can I find what is the correct term in GIMP.

 

Does the process of pixel reduction and file size reduction exist in GIMP, please?

 

If it does, what is the technical term, please, so that I can look it up in the documentation for GIMP?

 

Thank you for your help.

 

All the best,

 

Derek Mortimer
