PrepBatch: Bulk Image Tools

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.

EDIT
• Resize — fit, exact, max width/height or percentage, with a "don't upscale" option
• Crop — aspect presets, anchors, and content-aware Smart Crop
• Rotate & flip — plus Smart Rotate that auto-straightens photos and scans
• Color — brightness, contrast, saturation, grayscale
• Watermark — text or your own logo, drag to position, with fonts and opacity
• Border & frame

CONVERT & COMPRESS
• Export to JPEG, PNG, HEIC, TIFF, WebP and AVIF
• Quality control with an estimated output size before you commit
• Preserve or strip EXIF metadata, and remove GPS location with one tap

PRIVACY TOOLS
• Redact — automatically blur, pixelate, black out or emoji-cover faces
• Hide sensitive text like emails, phone numbers and addresses
• Cover barcodes and QR codes
• Remove Background to a transparent PNG

RENAME & ORGANIZE
• Rename with patterns: {name}, {counter}, {date}, {width}, {height}
• Preserve your source folder structure or export everything as a ZIP
• Handle name clashes: add a number, skip, or overwrite

AUTOMATE
• A "Process Images" action for Shortcuts
• Services menu and Finder Quick Action integration
