Cutout

The Cutout mode removes the background from a photo automatically and exports the subject as a transparent PNG.

This is the right workflow when you need a clean asset to reuse in e-commerce, presentations, layouts, or composites. Unlike Background edit (fast), the goal here is not to place the subject into a new scene, but to isolate it.

Use this mode when:

• you want to extract a person, product, or object quickly with transparency;
• you need a PNG ready for catalogs, marketplaces, decks, banners, or layouts;
• you want to prepare a subject for reuse in a composite or external tool;
• you do not want to write prompts and only need dedicated background removal.

• If you want the subject already placed into a new final environment: use Background edit (fast).
• If you need manual local cleanup or a targeted correction: use Single image edit.
• If you want to merge multiple images into one coherent scene: use Compose multiple images or Seamless Blend (subjects).

• 1 image.
• No prompt: the workflow is automatic.
• Supported input formats: PNG, JPG, GIF up to 10MB.
• To keep latency under control, images above 2048 px on the long side are resized before submission.
• For best results: clear subject, readable edges, minimal motion blur.

When you start processing, the app:

• sends your image to the dedicated cutout workflow;
• uses the specialized BiRefNet v2 model configured for Cutout mode;
• if multiple variants are enabled in your workspace, you can choose between Cutout Dynamic, Cutout Portrait, and Cutout Matting;
• segments foreground and background;
• refines edges and tries to preserve fine details such as hair, fur, lace, and semi-transparent areas;
• returns the result as a transparent PNG.

In this mode you typically see:

• Mode: workflow selector on Cutout.
• Model: if enabled in your workspace, lets you choose Cutout Dynamic, Cutout Portrait, or Cutout Matting.
• Image upload: upload the image to isolate.
• Workflow summary: automatic background removal, with no prompt field.
• Cut out subject: starts the process.
• Download/Save, Save to Drive, Share: export the final PNG.

Useful notes:

• Variations are not available in this mode;
• the output format is fixed to PNG to preserve transparency;
• the workflow uses BiRefNet v2 with one of the cutout models configured in your workspace;
• if you only see one model, that is the default model selected for your workspace;
• uploads in this mode are capped at 2K on the long side to avoid unnecessary latency;
• the three user-facing model names available in the app are Cutout Dynamic, Cutout Portrait, and Cutout Matting.

Quick rule:

• if you are not sure, start with Cutout Dynamic;
• if the main subject is a person, try Cutout Portrait first;
• if the difficult part is hair, fur, veils, lace, or transparency, try Cutout Matting.

This is the most versatile model. It is the best starting point for general cutouts and works well across many different types of subjects.

Use it preferably when:

• you are cutting out products, objects, animals, or full-body people;
• you are not sure which model to choose;
• you want a balanced default option for mixed use cases.

Typical examples:

• a shoe, bag, bottle, or e-commerce object;
• a full-body person you want to reuse in a layout;
• an animal or object with irregular edges but no difficult transparency.

This model is optimized for portraits. It is usually the best choice when the main subject is a person and the focus is on face, hair, shoulders, and body edges.

Use it preferably when:

• the image is a face shot, half-body portrait, or editorial portrait;
• you want to prioritize hair, face profile, and human contours;
• the isolated subject is clearly a person and fills most of the frame.

Typical examples:

• profile photo, headshot, business portrait, or social avatar;
• fashion portrait with visible hair detail;
• half-body subject for a presentation, team page, or banner.

This is the model to try when edges are soft and you need a more delicate extraction. It is designed for cases where edge alpha quality matters a lot.

Use it preferably when:

• there is flyaway hair, soft fur, or very thin edges;
• the subject includes veils, tulle, lace, or semi-transparent materials;
• you want smoother transitions between subject and background.

Typical examples:

• a portrait with lots of thin hair against a busy background;
• an animal with soft fur and fine detail;
• a dress with a veil, a lightweight fabric, or another translucent element you want to preserve as naturally as possible.

1. Upload the photo.
2. If available, choose the most suitable model: Cutout Dynamic, Cutout Portrait, or Cutout Matting.
3. Run Cut out subject.
4. Review the result at high zoom.
5. Save the transparent PNG.
6. Reuse it in a second workflow or an external tool if needed.

In the “Mode” selector, choose Cutout.

Drag or select the file. It works best when:

• the subject is clearly visible;
• there is readable separation from the background;
• the photo is not too compressed or blurry.

If the model selector is visible:

• use Cutout Dynamic as the starting choice for most subjects;
• use Cutout Portrait when the main subject is a person;
• use Cutout Matting when hair, fur, or transparency is the most delicate part.

If you do not see the selector, you do not need to do anything: your workspace is already using a default model.

Click Cut out subject. You do not need a prompt or builder in this mode: it starts directly from the image.

Check carefully especially:

• hair and fur;
• thin edges;
• transparent or semi-transparent materials;
• low-contrast areas against the original background.

Use Download/Save or Save to Drive to export the final result.

• Subject reasonably separated from the background.
• Sharp, well-lit photo.
• Readable edges around shoulders, hair, hands, or thin objects.
• Background not too similar in color or texture to the subject.

• In this mode you do not write a prompt: the behavior is specialized and automatic.
• Variations are not available.
• The final output is always a transparent PNG.
• The goal is subject isolation, so contact shadows and part of the original context may disappear with the background.
• If subject and background share very similar colors, edges may be less precise.

• Use a sharper source image with better subject/background separation.
• Avoid backgrounds with colors too close to the subject.
• If you are cutting out a person, try Cutout Portrait.
• If the problem is difficult hair, fur, or transparency, try Cutout Matting.
• If needed, do final cleanup in Single image edit on the exported result.

• That is expected: the goal here is an isolated subject.
• If you need a finished image with a realistic shadow, add it in the next step with Product photo mode, Background edit (fast), or a composite workflow.

• Crop first so the main subject is more dominant.
• Avoid inputs with secondary elements too close to or overlapping the subject.

• The mode tries to preserve them, but they are among the hardest cases.
• Start from cleaner, better-lit inputs and expect some manual cleanup when the result must be pixel-perfect.

• Background edit (fast): if you want to place the subject in a new scene.
• Product photo mode: if you want a final packshot or polished commercial image.
• Seamless Blend (subjects): if you want a more controlled composite.
