Hi Schmoo!

Good day to you! I pesonally prefer Adobe Photoshop when it comes to image: reduction, conversion, retouching, optimization...etc. In Photoshop, there are two ways to save images, one would be the usual way by using the Save as feature and selecting the file image type you wanted to be as (ex. png, tiff, jpg, gif, bmp...etc.). The second cool way of saving/converting images is through the "Save for Web" feature, where the image is save on the type of image file you want at the same time it is optimized so that it is not too heavy when used in the web. In this second option, you can reduce the file size of your image, convert it to whatever file type you want it to be and at the same time still keeping the image quality. The quality of the image is not preserved only when you have optimized it too much. If you have further queries on this we can talk it over in AO chat latr

A blessed day to all! Happy New Year
