Batch Cropper

Batch Cropper produces a ready-to-train image dataset: resized and cropped files, converted to PNG, JPG or WEBP (or left in their original format), with a caption for every image, all bundled into a zip download.

Pricing is not something you need to worry about here, since nothing is said about plans.

BatchCropper is a bulk image resizing and cropping tool built mainly for people preparing FLUX LoRA training data.

You upload multiple images, set the exact dimensions you want, and crop where an image needs it.

That covers the tedious part of dataset prep, where every file has to match the same size and format before training starts.

The caption feature is the part that sets Batch Cropper apart from a plain resizer.

It generates a caption for each image you include, which is meant to improve your LoRA training results.

If you build AI models and spend time hand-prepping image folders, the one-step zip export saves real effort.

If you only need to shrink a few photos, a general photo editor will do the job just as well.
