PrepBatch
Bulk image editing for Mac, done right.
Build a recipe of edits once — resize, crop, convert, compress, watermark, redact and rename — preview it live, then run it across hundreds of images at once. All on your Mac.
Everything in one pass
A recipe for your whole batch
Stack operations in any order, see a live before/after preview with an estimated output size, then process every image in parallel.
Resize & crop
Fit, exact, max width/height or percentage. Aspect crops and content-aware smart crop.
Convert & compress
JPEG, PNG, HEIC, TIFF, WebP and AVIF with quality control and a live size estimate.
Watermark
Text or your own logo — drag to position, choose fonts, opacity and placement.
Redact
Blur, pixelate or emoji-cover faces, and hide emails, phone numbers, addresses and QR codes.
Remove background
Cut out the subject to a clean transparent PNG, powered by on-device Vision.
Rename & organize
Pattern-based renaming, preserved folder structure, ZIP export and EXIF/GPS control.
Preview before you commit
Every edit shows up instantly on the selected image, with the estimated output size — so there are no surprises across a thousand files.
- Live before / after preview
- Estimated output size per image
- Reorderable, collapsible operation cards
Private by design
Nothing leaves your Mac. Detection and processing run entirely on-device — no uploads, no accounts, no tracking.
- Redact faces & sensitive info
- Strip metadata & remove GPS location
- 100% offline, Apple-frameworks first
