사용 방법
- Drop one or more JPG, PNG or WebP images into the tool.
- Start Remove Background to send the selected images to the configured server processor; uploaded source images are deleted after processing.
- Review the edge, adjust feather or threshold, and use Erase or Restore for small corrections.
- Keep Transparent for a PNG, choose a solid or custom image background, then download files or a ZIP.
이런 경우에 유용합니다
- Product photos and catalogues
- Profile pictures and portraits
- Pets, objects and social media graphics
How to remove an image background
Add a JPG, PNG or WebP, then choose Remove Background. The selected image is sent to the configured server processor, which returns a transparent result for review and export, then deletes the uploaded source image.
How server-enhanced background removal works
The server processor runs the segmentation model and returns an alpha matte. Preview rendering, edge refinement, manual mask edits and final export happen in your browser after the inference response arrives.
How to create a transparent PNG
Keep Transparent background selected and download the PNG result. The checkerboard is only a preview; the downloaded file contains a real alpha channel.
How to refine hair and object edges
Use the Feather, Threshold, Smooth edge and Expand/contract controls for small edge changes. Use Erase to remove leftover background and Restore to bring back a missing part of the subject. Inspect the result on both white and black previews.
How to replace an image background
Select Solid color or Custom image. A custom background is loaded locally and composited below the foreground. JPG output is flattened, while PNG and WebP can keep transparency when Transparent is selected.
Are images uploaded?
Yes. This tool uploads the selected image to the configured processing server for background-removal inference. The BrightTools processor deletes the uploaded source image after processing and does not put image data, file names or masks into analytics. If a deployment points to an external provider, review that provider's retention policy before sending sensitive images.
Why background removal may be imperfect
Low contrast, reflections, transparent objects and complex hair can be difficult for any automatic matte. Manual repair is provided so you can review the edge before publishing.
Server and browser requirements
The configured server processor runs the AI inference. A stable connection to the processing endpoint is required; large images may still require more memory while the result is previewed and exported.
알아둘 점
Automatic mattes can need review around fine hair, reflections, transparent objects or low-contrast backgrounds. The server-enhanced model is designed for varied subjects, but no model promises perfect results for every image.
자주 묻는 질문
Are my images uploaded?
Yes. Background removal sends the selected image to the endpoint configured by the site operator. The BrightTools processor deletes the uploaded source image after processing and does not retain it. If the site uses an external endpoint, that processor’s retention policy applies.
Is background removal processed locally?
No. Background-removal inference runs on the configured server processor. Preview rendering, mask edits and final export still run in your browser.
Can I remove backgrounds from multiple images?
Yes. Add multiple images and use Remove All Backgrounds. The queue uses one task on touch devices and up to two on desktop.
How do I fix missing or incorrectly removed areas?
Choose Erase or Restore, set brush size, hardness and opacity, then paint over the result. Undo and redo only store mask edits.
Can I download a transparent PNG?
Yes. Transparent is the default background and the output receives a real alpha channel. The checkerboard is only a preview.
Can I replace the background with another image?
Yes. Load a local background image, then choose Custom image. The foreground remains above it and the background never leaves your device.
Why are hair edges difficult to remove perfectly?
Fine hair mixes foreground and background colours at the pixel level. Inspecting on white and black backgrounds and using Feather, Erase and Restore gives you control over the final edge.
