Your images are processed locally in your browser and are not uploaded.
Drop a folder’s worth of photos, set the target size — for example 1200 × 1200 — and optionally convert to WebP and remove metadata. Images are processed in parallel on your device, so even large batches finish quickly without uploading anything.
