Background Remover
This lesson is part of Web Developer Tools · All levels
Summary
The background remover automatically separates the main object in the photo from the background, and then produces a transparent background image. The result is usually stored as PNG or WebP because both formats support alpha channels. The quality of separation depends heavily on the contrast between the object and the background, as well as the complexity of the edges such as the hair or feathers.
Key points
- The best results are stored in a format that supports transparency, like PNG.
- Plain background and high contrast facilitate the separation of objects
- Fine edges like hair often need to be manually checked and refined
- Alpha channel determines the level of transparency of each pixel
- Always check the results on a light and dark background before use
