Image Converters

Oftentimes you’ll encounter a situation where a photo or image needs to be smaller to fit into an upload of an assignment or as an attachment for an email. In this case, converting images from lossless formats such as PNG to lossy formats like JPG can be your best bet. Software such as IrfanView and XnConvert will facilitate this.
