PrepBatch: Bulk Image Tools

Georgios Trigonakis

PrepBatch is a fast, private batch image editor for Mac. Build a recipe of edits once — resize, crop, convert, compress, watermark, rename and more — preview it live, then run it across hundreds of images at once. Everything happens on your Mac. No accounts, no uploads, no tracking. BUILD A RECIPE, RUN IT ON EVERYTHING Stack operations in any order, watch a live before/after preview with an estimated output size, then process your whole batch in parallel. Save recipes as presets for one-click reuse.
