BMP to JPG

This lesson is part of Web Developer Tools · All levels

Summary

Conversion of BMP to JPG uses lossy compression to reduce the size of very large files, especially in photos. Since JPG does not support alpha, BMP transparency must be leveled first. The result is much smaller and easier to share, but keep the original BMP if you still need uncompressed pixel data.

Key points

JPG can drastically reduce the size of BMP files
JPG compression is lossy and permanent on the copy
Transparency not supported by JPG
Use the 85-90 quality for the photos to keep the detail good.
Avoid re-storage of JPGs over and over again to prevent artifacts
