Downsize

Downsize is a simple but handy application that allows you to resize multiple images at once, and even add frames and watermarks.

You just need to select the source, which can be a single file or a complete folder. If it is a folder, the program will show the number of images it contains and you will be able to preview them. The three processes (resizing, watermarking and framing) can be done simultaneously, so you simply adjust the desired parameters, select the output location and click on "Process images".

For the resizing, you can select the max width and height in pixels, customize the resize quality, or select the compression quality by adjusting the meter to the desired percentage. For the watermarking, you just add the image you wish to use as the watermark or type the desired text. For the text watermark, you can customize the font and color. You can also select the location in the images, opacity, and edge distance. For the framing, you can customize the thickness, color, corner radios, background color, shadow, etc.

Thus, if you need a simple application to perform multiple changes at once, Downsize may be a good choice.
