if the dimensions fit, and the compression level is decent, why re-compress? Check out the article Dimensions and Quality For Social Media Photo Sharing for further details. However, sometimes users upload good images so if you do some analysis, you can minimize that requirement resulting in better image quality overall. In many scenarios you may have to do some form of resizing which involves recompressing the uploaded images. Your applications may allow users to upload images. Minimize unnecessary recompression of user images See the blog post Normalizing uploaded image rotation for further information.

This is not so much an issue any longer in 2022, but in case you have custom apps that display images, or if you are dealing with legacy browsers etc., chances are that images may be displayed with an incorrect orientation. To be aware of the metadata in images is actually quite important, even if you don’t care about the metadata themselves. In this first part, I would like to examine the reasons of why image metadata may matter to you as application developer. In order to shed some light into this mess, I am doing a little mini-series. Which library to use also depends on your use-cases: Do you solely need to read metadata or is the writing of metadata essential for your business use-cases?
