BMP vs PNG
BMP: BMP is an uncompressed bitmap format from Windows. Files are very large and rarely accepted by modern websites.
PNG: PNG uses lossless compression and supports transparency, which makes it ideal for logos, screenshots and graphics. Files are usually larger than JPG.
Transparency is preserved.
Good to know
- Converting between formats does not improve the original quality.
- Metadata such as location and camera info is removed during conversion, which is good for privacy.
- HEIC files from iPhones are not supported by every browser. Change your iPhone camera setting to "Most Compatible" or export as JPG first.
