BMP vs WebP
Which image format should you choose?
BMP wins on lossless and simple to read. WebP wins on 25–35% smaller than jpg and png. For most general use, pick whichever is more compatible with your existing tools — file size and quality differences are usually small at the same encoding settings.
When to use BMP
Choose BMP when you need windows software compatibility or embedded systems and microcontrollers. Its strengths: lossless and simple to read, and wide windows software support.
Pros
- + Lossless and simple to read
- + Wide Windows software support
Cons
- − Massive file sizes — no compression
- − No transparency
- − Should be converted to PNG or WebP for modern use
When to use WebP
Choose WebP when you need web images and core web vitals optimization or replacing jpg and png to reduce page weight. Its strengths: 25–35% smaller than jpg and png, and supports both lossy and lossless.
Pros
- + 25–35% smaller than JPG and PNG
- + Supports both lossy and lossless
- + Transparency and animation in one format
Cons
- − Not supported by some image editors
- − Older browsers (Safari < 14, IE) lack support
- − Less mature ecosystem than JPG/PNG
