Many times you may need to resize multiple files to a common size, either for uploading to a web-site, sending by email, or for some other purpose. Manipulating the size of an image can be very confusing for both newbies and experienced users. How to resize an image to the exact dimensions, while maintaining picture quality, can be tricky. With ImageConverter Plus you can quickly resize photos by centimeters, inches, pixels or percentage. Which unit to use is a matter of your own preference. People from the Unites States may prefer to use inches, whereas those in other countries may prefer centimeters. Pixel values are not generally recommended to define sizes, but they may be appropriate in some cases. If you want to set a new size of an image taking into account the size of the original image, percentage can be chosen as the main resize category.
