Select the TIFF files
In Finder or on the Desktop. One file, or a whole folder with ⌘ A.

FileFlip opens next to the selection and lists the formats it can make from TIFF. Type “BMP” to jump to it.
Choose BMP and press Return
The BMP files appear next to the originals with the same names. The TIFF files stay as they are.
TIFF and BMP
TIFF files are very large and web browsers and many apps won’t show them. Some older Windows software and hardware only accept BMP.
What changes when you convert
- Both formats are lossless, so the image itself doesn’t change. Only file size and compatibility do.

Other ways on a Mac
For one file now and then you may not need FileFlip. These work with what’s already on your Mac.
Preview
Open the TIFF in Preview, choose File → Export, pick Microsoft BMP from the Format menu and click Save. If Microsoft BMP isn’t listed, hold Option while you click the Format menu. For several files, open them together, select all thumbnails in the sidebar and choose File → Export Selected Images.
Good for a few files now and then.
Terminal
The sips command converts images in place or into a new file.
sips -s format bmp scan.tiff \
--out scan.bmpBuilt into macOS and good for scripts. Run sips --formats to see what your macOS version can read and write.
