Make Background Transparent
This lesson is part of Web Developer Tools · All levels
Summary
The transparent background maker transforms a particular background color into transparent based on the chosen color and its tolerance. This is similar to a chroma key: it's suitable for plain background, but not for artificial intelligence-based object separation. The best results are stored as PNG or WebP so that alpha channels remain available.
Key points
- Choose the really dominant background color so the result is clean.
- Tolerance determines how similar a color should be to being transparent.
- The edges of the object can leave a halo if the background is not uniform.
- Objects with a background-like color are at risk of disappearing.
- Use PNG or WebP to store transparent results
