PNG to GIF
This lesson is part of Web Developer Tools · All levels
Summary
PNG to GIF conversion is useful when you need a highly compatible format or want to create a simple animation. GIFs only support 256 colors per frame and one bit transparency, so the fine gradation on PNG can be converted to a color tape. For rich-color photos or illustrations, PNG or WebP usually yield better results.
Key points
- GIFs are limited to a maximum of 256 colors per frame
- GIF transparency is only one bit: full or opaque transparent pixels
- Dithering helps disguise the color band on gradations
- GIFs support animation, but the number of colors remains limited
- Converting multi-colored PNG to GIF can lead to appeal
