Batch workflow
Drop images into the workspace, review the intake list, choose resize and format settings, then export the batch as individual files or a packaged archive.
Documentation
Practical notes for moving through Frostbatch quickly: import a batch, choose output rules, preview changes, and export clean image sets without leaving your Mac.
Presets
Use platform presets for App Store, Amazon, Instagram, and common web outputs. Presets can be adjusted before export, so you can keep the shortcut without losing control.
AI upscaling
Premium builds include local Real-ESRGAN upscaling at 4x, with a Photo model for camera work and an Illustration model for flat art. Processing stays on device, with no cloud upload or external image service.
Watch folders
Point Frostbatch at a folder and it can process new files as they arrive using the current settings or a saved rule.
