On-device AI, no cloud round-trip
Every AI feature runs locally on Apple silicon via Apple's MLX framework. Weights are downloaded once and reused — no per-image API fees, no images leaving your Mac.
AI Image Generation
On-device AIText-to-image generation, fully on-device. Reference images supported for restyling and composition.
AI Upscale
On-device AISharpen and enlarge photos with on-device AI. Multiple modes for photos, anime, and video.
AI Cutout
On-device AIPrecise background removal with subject + hair edge refinement. Choose fast or flagship quality.
AI Eraser
On-device AIPaint over unwanted objects, the background fills in naturally. Iterate as many times as you need.
AI Anonymize
On-device AIAuto-detect people and vehicles, then blur or mosaic them. Toggle each instance on or off before applying.
AI Face Restore
On-device AISharpen blurry or low-quality face features in old portraits. Faces only — backgrounds, scratches, and fading stay as-is.

FAQ
What image formats does OtterPix support?
Read and write: JPEG, PNG, TIFF, BMP, HEIC, WebP, AVIF. PDFs can be rendered to images at any DPI. Most operations preserve color profiles and EXIF orientation.
Does the OtterPix Mac app upload my images or collect any data?
No. Every operation — including all AI features — runs locally on your Mac. The Mac app contains no analytics SDK, no telemetry, no image upload. Its sandbox entitlements grant network access only for downloading model weights from Hugging Face on first use of each AI feature, and for App Store subscription verification. (Note: this marketing site at otterpix.app does use Google Analytics 4 with your consent; see our Privacy Policy.)
Do the AI features need an internet connection?
Only for the one-time model download. After that, every AI feature works fully offline. Model sizes range from a few megabytes (smallest upscale model) up to several gigabytes (the image-generation model). You choose which models to download from the AI settings panel.
Which AI features ship today, and how do they run?
Six on-device AI features: image generation, image upscaling, background cutout, object eraser, anonymize (people / vehicle blur), and face restoration. All inference runs through Apple's MLX framework, accelerated by the Neural Engine and GPU on Apple silicon. Each feature uses an open-source model bundled with the app; license attributions and full credits are listed in the app's About screen.
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.
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.
