60% smallerMeasured from this sample. Results vary by image and settings.
Save your settings as presets. Process new files automatically. Keep every image on your Mac.
Real‑ESRGAN rebuilds detail at 4× before the resize, on your Mac's GPU. Two models: Photo for camera work, Illustration for flat art and line work. Slow, and worth it when the source is small.
Web development, e‑commerce, blogging and social, photography, office. A preset loads its numbers straight into the sidebar, so you can see what it will do and change it. A bundle writes several sizes from one source in a single run.
Point Frostbatch at a folder and anything dropped into it is processed on arrival, with your current settings or a separate set saved for that folder.
Strip EXIF, GPS and camera data before you share. Nothing is uploaded; there is no account and no server.
Give the batch a filename pattern. {name} keeps the original, so {name}@2x turns hero.jpg into hero@2x.jpg.
Drag a frame on any single image. The crop is applied before the resize and stays saved if you reopen it.
Captured from the shipping build, not mocked up.
Open JPG, PNG, WebP, AVIF, TIFF, and HEIC. Export as JPG, PNG, WebP, AVIF, or TIFF. iPhone HEIC photos become JPG when you choose Original.
Five days of the full app, then $0.99 through the App Store. No subscription, no credits, no account.

US price shown. Local pricing is provided by the Mac App Store.
The Mac app is $0.99 once through the Mac App Store, with nothing to renew.
You get five days of the full app. After that, starting a new batch asks you to unlock it for $0.99. Nothing you have already exported is touched, and there are no prompts before the five days are up.
The Mac app processes everything locally, including AI upscaling, with no image uploads.
It runs Real-ESRGAN over each image at 4× before the resize, which rebuilds detail rather than stretching pixels. Choose Photo or Illustration. Upscaling takes longer than resizing and works best on small images.
It needs macOS 13 (Ventura) or newer and a Mac with Apple silicon. Upscaling uses the GPU where there is one and falls back to the CPU otherwise.
Not at the moment. The Mac App Store is the only place to buy it.
It reads JPG, PNG, WebP, AVIF, TIFF and HEIC, and writes the first five. Pick Original to keep each file's own type; HEIC is the exception and comes out as JPEG, because there is no HEIC encoder to write back to.
Either into a zip you choose the location for, or over the originals in place if you pick Rewrite. The zip is named batch- plus a timestamp by default, and you can change that prefix.
Five days free, then $0.99 once. macOS 13 or newer.
