Resize photos in Photoshop
22nd July 2013. It is quite easy to resize an individual images in Photoshop. Here I will first explain how to resize a single picture and then go on to explain how to resize multiple images within Photoshop.
Resize individual photos in PhotoshopTo resize an individual image, you should choose the menu: Image > Image size. You will then get the dialog box seen in Picture 1. If you are to reduce the size simply to send the image in an E-mail or use on a blog, you leave the settings as is, and modify the height or the width. When you are doing so the other setting will also automatically change and the image will look practically the same, only smaller. Generally you should avoid increasing the image size because this will greatly reduce the quality of the image. The setting "Document size" is only meant for print size and if you want to modify the print size setting, you should uncheck the setting "Resample image", particularly if you plan to increase the image size. If you don't uncheck it when increasing the print size, Photoshop will try to add information without really having sufficient knowledge. When un-checking the resample option, you can increase the size for print and the resolution will correspondingly be reduced.
Resize multiple photos in PhotoshopOften you wish to reduce the image size of multiple images in one process. You get to the necessary dialog box by entering File>Scripts>Image Processor (Picture 2). You will then get the box seen in Picture 3. In the first step labeled as "1" in the Photoshop box, you see that it is preferable if you have chosen the pictures beforehand and put them in a particular folder. Otherwise you would have to open the pictures and then use the "Use Open Images" option. Third option in step one is if you prefer to also resize the images in the sub-folders. If all you are about to do is to resize the images, there is no point in opening the first picture to apply settings. In the second step you naturally build on what you did in step 1. You choose the output folder, and whether you should keep the same folder structure, if you chose to include sub-folders in step 1. Naturally, if you change file format you can save the files in the same folder. The third step basically determines the quality of your output file. The "Quality" option is among the weaker parts of Photoshop as it only has a very limited amount of opportunities, unlike e.g. Fireworks that has settings from 0-100%. For most uses on the web or to send something via E-mail, eight (8) is a good setting. You naturally have to test which is appropriate for your particular use. Resize to fit is the most useful way of batch resizing many images. Here you define what is the largest height or width in each of the pictures. If you choose 800 as a value, no picture will be larger than 800. Probably each of the pictures you resize will then either be 800 in width or 800 in height with the same height to width ratio.
