Rotate, crop, resize and watermark in a single pass so a whole folder comes out the same. Useful when the source images are all different sizes.
Doing this one image at a time is fine until about the twentieth file. Batch edit lets you set rotation, cropping, resizing and a watermark once, then applies the same rules across the whole folder. Each step is optional — anything you leave off is skipped.
The order is fixed: rotate, then crop, then resize, then watermark. There is a reason for each position. Rotating after cropping would move your crop to the wrong part of the picture. Watermarking before resizing would shrink the text along with the image, so the mark would come out a different size on every file. Rather than letting you rearrange the steps into a broken order, one order that always works is enforced.
The crop area you draw on the first image is remembered as a proportion, not as fixed pixels, so the same composition lands correctly on photos of different sizes. Resizing can key off the width, the height, the long edge or the short edge — which means a folder with both landscape and portrait shots comes out consistent in a single pass.
Everything runs inside your browser. Because the image never reaches a server, we cannot store it or look at it. That difference matters when the file is company material or a personal photo.
