Crop one image into multiple exact sizes at once, then export them all together. Runs entirely in your browser — no upload, no sign-up, no watermark. Set up your size templates once — 1600×1600 for a listing, 1080×1920 for a story — then drop in one image and export all of them at once. Runs entirely in your browser: no upload, no sign-up, no watermark. Give a template a max file size in KB and it finds the quality that fits.
