BMP vs JPG
Which image format should you choose?
BMP wins on lossless and simple to read. JPG wins on universal device and browser support. 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 JPG
Choose JPG when you need digital photography and camera output or sharing photos on social media. Its strengths: universal device and browser support, and excellent compression for photos.
Pros
- + Universal device and browser support
- + Excellent compression for photos
- + Very small file sizes
Cons
- − Lossy — quality degrades each time you re-save
- − No transparency support
- − Poor for graphics, logos and line art
