HOW IT WORKS

Professional backgrounds, without sending your image anywhere.

Choose an image, press Apply AI background removal, then try illustrated scenes, a custom background, shadows, placement and color adjustments. Download your result in seconds after processing.

01

Private by design

Image edits run locally. On first AI use, the browser downloads a free segmentation model and runtime from public hosts.

02

Know the limits

AI automatic cutout is optimized for people. Objects and complex edges may need manual corrections.

03

Creative control

Build stylized scenes, upload your own environment, adjust subject lighting and export with transparent backgrounds.

Frequently asked questions

Are images uploaded to a server?

No. Images are processed by this page in your browser. The AI runtime and model are fetched from public hosting only when you first apply AI removal. They are third-party resources; the model must load for AI processing to work. The MediaPipe runtime may also transmit usage/performance metrics under its privacy notice.

Does the app generate photorealistic AI backgrounds?

No. It uses procedural illustrated backgrounds, keyword-based preset selection and custom background uploads. It does not include local diffusion or commercial generative APIs.

Does automatic removal work for products or animals?

The built-in selfie segmenter is trained mainly for people. For objects, use the manual masking brush or upload an image with a transparent background.

Using AI Background Generator

Import a photograph and choose person segmentation, a manual mask or supported solid-background removal. Refine the selection, select a procedural scene or your own background and adjust the composition. Export the composite, subject or mask.

AI identifies people rather than general products or animals. Scene text selects procedural presets; it does not generate diffusion images. MediaPipe downloads runtime/model assets and may send provider usage/performance metrics. Cancellation discards a result but cannot interrupt an already synchronous model call. Working images can be scaled down to 2560 pixels/7.5 MP. JPEG flattens transparency to white.

Workflow and output choices for AI Background Generator

Separate a person from a supported photograph with optional segmentation or a manual mask, refine the matte and place the subject over a procedural scene or your own background.

Scene presets are procedural, not generated photos. Export the composite, subject or mask; JPEG flattens transparency to white.

Example workflow

  1. Open a photograph and choose person segmentation, manual masking or supported solid-background removal.
  2. Refine the subject mask and select a procedural scene or local background photo.
  3. Adjust the composition and export the composite, isolated subject or mask.

Authored example: Use an authored example of a portrait against a busy background. Compare the person mask with a manual correction around hair; the exercise does not claim perfect segmentation.

Limits and model handling: The optional MediaPipe segmenter identifies people, not arbitrary products or animals; scene text selects procedural presets rather than generating a new image. Model/runtime requests contact external providers and may send provider usage/performance metrics. Cancellation cannot interrupt an already synchronous inference call.

AI Background Generator questions

Does scene text generate a new image or product background?

No. Text selects procedural scene presets; the tool does not generate diffusion images.

Does AI segment every object in the photo?

No. The supplied model is for people. Use a manual mask for other subjects and review all edges.

LOCAL AI SETUP

Set up AI on this device

First, a segmentation model must be loaded on your device

MediaPipe Selfie Segmenter runs locally using CPU/WebAssembly after you explicitly choose Download & Load Model. Runtime files come from jsDelivr and model weights from Google. Manual masks, solid-color removal and illustrated scenes remain available without AI. This does not generate photorealistic backgrounds from text.

No localStorage, IndexedDB, projects or unrelated files are automatically cleared. MediaPipe HTTP caches may be inaccessible.

Run a read-only cache scan before optional cleanup.

Unknown or inaccessible model storage is skipped. Close other AI tool tabs before deleting shared model caches.

Having trouble downloading or loading AI?

Try Refresh Storage & Cache, Retry Setup, and check network/CDN access. Inspect caches when a known model download is incomplete. Removing other models is optional and will not fix every error.

Never clear all website data without backing up your saved PixelOkay work.
