Image requirements & best practices
What we accept and what tends to work best. Following these guidelines helps you get more consistent results and avoids common pitfalls. This page covers formats, size limits, resolution, and practical tips for better cutouts.
Supported formats and size
| Format | Max file size (web) | Notes |
|---|---|---|
| JPG / JPEG | 12 MB | Most common for photos. Output is PNG. |
| PNG | 12 MB | Supports transparency in input. Output is PNG. |
| WebP | 12 MB | Supported for upload. Output is PNG. |
On the free web tool, standard resolution is used. Suitable for web, social, and most projects. For very large prints or ultra-high-resolution needs, consider downscaling the output or using the API with the "full" size option if available.
Resolution and quality
The tool works on images up to 12 MB. Higher resolution generally gives the model more detail to work with, which can improve edge quality, especially for fine details like hair or fur. Very low-resolution images (e.g. under 400px on the long side) may produce softer or less precise edges. For best results, use a clear image that is at least 800px on the longest side when possible.
Output is always PNG with transparency. The resolution of the output matches the input (or the processed size we use internally). There is no upscaling; if you need a larger final image, start with a higher-resolution source.
Tips for better results
-
1
Clear subject. The main subject (person, product, object) should be clearly visible. Cropped or partially hidden subjects can confuse the model.
-
2
Contrast with background. When the subject stands out from the background (different color, brightness, or focus), results are usually better.
-
3
Good lighting and focus. Well-lit, in-focus images give the AI clearer edges to work with. Blurry or very dark photos may produce rougher cutouts.
-
4
Single main subject. One clear subject per image tends to work best. Crowded scenes or multiple overlapping subjects can be harder to separate.
Common issues and fixes
If the result looks rough around the edges, try an image with better contrast between subject and background, or with sharper focus. If parts of the background remain, the scene may be too busy or the subject too blended with the background; a simpler photo or a different crop often helps. We do not support batch editing in the free tool; process one image at a time for the best control.
For product photos, a plain background and even lighting usually give the cleanest cutout. For people, a clear outline (e.g. portrait with visible shoulders) works better than heavily cropped or overlapping subjects.
What we don’t support
We don’t accept GIF, BMP, or TIFF for the web tool. Animated images are not supported; only the first frame would be used. For legal and safety reasons, don’t upload content you don’t have rights to or that violates our Terms of Service.
