Images from digital cameras can be saved in various formats that may eat up a lot of space on the hard disk of the system due to their sheer size. It is advisable to re-size the image in order to avoid these problems. Saving the pictures in the low size JPEG format helps, but the picture quality and the resolution may be reduced. Specific professional software dedicated to image re-sizing is available online, which can help maintain image quality too. This article will show you how to optimise any size reductions.
There are several reasons for resizing images. Digital cameras save photos in different image formats which may take a lot of space in terms of size on your hard disk. This can be particularly problematic when sending files via email or uploading them to websites. By resizing your image, you will benefit by saving disk space and reducing image upload times.
JPEG is a low size image format, which allows for image resizing. However the main disadvantage of this tool is that when saving an image under this format, it can lose its resolution and image quality can be reduced.

You can choose the quality of JPEG files, (between 1% and 100%):
If you want to resize an image on an Apple Device, it is relatively simple to do so using Preview.
