rEASYze is a free and portable app with Easy and Pro modes for resizing your images.

rEASYze makes it easy for anyone to use with the Easy and Pro modes for any skill level. In Easy Mode, simply drag-and-drop your images into the Window. Drag your photos into the Window and use the Zoom slider to crop your image to the size you want. We had no luck dragging and dropping or selecting GIF and JPG images into the Window in Easy Mode. rEASYze just opened the new folder and not the picture. Because of this using Pro mode is your best move.

Pro Mode isn't too challenging and adds enough settings that anyone can quickly figure out. You can choose the width and height you want, the format (JPG, PNG, TIF, GIF, BMP), landscape, portrait, degree of rotation, rename, preview, gray, sepia, and more. As of version 1.5 labeling and watermarking is also available. Overall, we'd default to the Pro Mode.

rEASYze is as simple to use as you like while adding lots of additional features for those looking for more power in image resizing. Watermarking alone is a great feature rarely found for free and certainly not in a small, portable app.
