About BMP and PNG
- BMP is Windows' old uncompressed bitmap format. Files are very large for their size in pixels, and most websites, chat apps and phones won't accept them.
- PNG is a lossless format: it keeps every pixel exactly and supports full transparency. That makes it ideal for screenshots, logos and graphics, but photos saved as PNG are often several times bigger than the same photo as a JPG.
Tips for Android phone
- No app from the Play Store needed, so there are no extra permissions, ads inside an app or storage used.
