BMP vs PNG
Which image format should you choose?
BMP wins on lossless and simple to read. PNG wins on lossless — no quality loss when re-saved. 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 PNG
Choose PNG when you need logos and graphics with transparency or screenshots and ui mockups. Its strengths: lossless — no quality loss when re-saved, and full alpha transparency.
Pros
- + Lossless — no quality loss when re-saved
- + Full alpha transparency
- + Universal browser and software support
Cons
- − Much larger files than JPG for photos
- − No animation (use APNG or GIF)
- − Outperformed by WebP and AVIF on the modern web
