FAQ

What image formats does OtterPix support?

Read and write: JPEG, PNG, TIFF, BMP, HEIC, WebP, AVIF. PDF pages can be rendered to images at 72, 150, 300, or 600 DPI. Most operations preserve color profiles and EXIF orientation.

Does the OtterPix Mac app upload my images or collect any data?

Your files and AI inference stay on your Mac. The app has no analytics SDK or usage telemetry and never uploads images, prompts, recognized text, or usage data. It does make limited HTTPS requests for Apple StoreKit, a startup edge-country lookup used only to choose a model-download mirror, a small URL-only model manifest when model delivery is first used, and model downloads you start. (This marketing site at otterpix.app uses Google Analytics 4 only with your consent; see our Privacy Policy.)

Do the AI features need an internet connection?

A network connection is required to download the model weights you choose. The app also makes small StoreKit, download-routing, and model-manifest requests described in our Privacy Policy; if they fail, the app keeps working. Once the required weights are present, image processing and AI inference run without cloud processing. Task-specific model and quality choices stay in each feature; AI Settings shows the same resumable download progress and manages storage.

Which AI features ship today, and how do they run?

Seven on-device AI features: image generation, image upscaling, background cutout, object eraser, anonymize (people / vehicle blur), face restoration, and text recognition (OCR). Downloadable model inference uses Apple's MLX framework on Apple silicon, with GPU acceleration and unified memory. Open-source model weights are downloaded on demand rather than bundled with the app; licenses and full credits are listed in About.

What Mac do I need?

macOS 14 (Sonoma) or later, on an Apple silicon Mac (M1 or newer). Intel Macs are not supported because MLX targets the unified-memory architecture. For AI image generation we recommend 16 GB RAM or more.

Does OtterPix support batch processing?

Yes — the Pipeline feature lets you chain any combination of operations (convert, resize, crop, watermark, upscale, cut out…) into a single preset and run it across a whole folder of images.

Can OtterPix work automatically, or from Shortcuts and AppleScript?

Yes. Folder Automation, part of Pro, watches a folder you choose and applies a saved Pipeline preset to every new image. With the menu bar icon turned on, OtterPix keeps running after you close its window, so watched folders keep working, and you can drop images or a folder on the icon to load them into the Pipeline. Shortcuts and AppleScript run the free tools, and presets built from them, at no cost; a step that uses a Pro AI feature needs Pro. Everything still runs on your Mac.

Where can I download OtterPix?

OtterPix is available now on the Mac App Store — free to download, with the basic tools free forever and Pro as an in-app purchase.
