| What you get back | A transparent PNG of the subject at the source size | A transparent cut-out, usually with a similar set of controls | A finished photo with a new scene behind the subject | A finished photo with a softened version of the same background | Whatever you build mask by mask, at whatever quality your hand achieves |
|---|
| Does the background carry alpha? | Yes - the background pixels are transparent | Yes - this is the same deliverable | No - the new scene is opaque and baked in | No - the blurred background is opaque and baked in | Yes, if the export keeps its alpha channel |
|---|
| Partial alpha on soft edges | Kept where the model resolves the edge | Kept, and the strongest dedicated tools are very good at it | Not applicable - nothing is cut out | Not applicable - nothing is cut out | As good as your mask, which for hair can be excellent |
|---|
| Original pixel size preserved | Yes - no trimming, padding or rescaling | Usually, though some tools resize or crop | Depends on the model that renders the scene | Yes, the source size is kept | Yes, you control the canvas |
|---|
| Inspecting alpha against different backdrops | Built in: checkerboard, black and white, with zoom, before you download | Varies by tool; some offer a single flat preview | Not applicable - there is no alpha to inspect | Not applicable - there is no alpha to inspect | Yes, in the editor, with a real layer stack |
|---|
| Where it sits in your work | The same account, credits and history as the rest of your image work (5 credits per photo) | A separate account and a separate subscription | The same IMG AI account, but a different deliverable | The same IMG AI account, but a different deliverable | A desktop editor you already own |
|---|
| Best for | Product, portrait and asset work that continues elsewhere on this site | Volume cut-outs, when a dedicated tool is already part of your workflow | Selling a product in a styled scene | Making a busy background recede without changing it | A single hero image where the edge has to be perfect |
