Movavi Photo Batch helps you to save time when you want to perform the same edit across a large batch of photos. It supports batch photo editing for all the basic functions like resize, change format, rename, rotate and adjustment. It is relatively easy to use with all the main features arranging in a column of buttons on the right side. You will be able to see all the photos load into the software in thumbnails.
You can try out Movavi image optimizer by downloading it from the Movavi site. It only takes a while to run the installation once the file is downloaded to your computer. When you open Movavi Photo Batch, the first step is to load the photos. You can click on the + Files button to load the photos one by one. You can click on the + Folder button to load one or more folders of photos into the gray openspace. One can also conveniently drag the photos into the gray open space to load them.
To optimize your image, you can select the resize button to scale your image to a smaller size. It offers several resize options including scale by width or height only, scale by percentage or custom size. If you scale by width only, you only have to enter the value for the width so that the height will remain in the original measurement.
In scale by percentage, it can change the image size by a specified percentage from 0 to more than 100%. For example, if you want the image to appear half smaller, you can enter the value 50%. You just have to enter 50% in the height and the width will be automatically adjusted. You can also enter a custom resolution for the image if you know the exact height and width.
Besides, it allows you to convert your images into 3 other formats including jpg, png and bmp. JPG is the most compressed image format of the three formats. When converting your images into JPG, you can drag the image slider quality backward to reduce the file size. When you drag the slider to the left, the image quality will drop. It may appear fuzzy if you drag too far to the left so you should drag it around until you arrive at a quality that is all right for viewing. It is recommended that you set the quality for the JPEG to 70% if you want to reduce the file size.
Finally, when you are done optimizing your images, you can click on the Batch Export button to start the conversion process. A dialog box will pop up and you must choose whether you want the image files to be saved to a new folder or the original folder. You can also choose the option for the software to rename the converted image files and have them saved next to the originals. It takes a few minutes for the batch photo conversion to complete. When it is done, it will automatically open the destination folder and you can go through all the images to check them yourself.
