TIFF and PNG
TIFF files are very large and web browsers and many apps won’t show them. PNG keeps every pixel and supports transparency, which is what you want for screenshots, graphics and further editing.
What changes when you convert
- Both formats are lossless, so the image itself doesn’t change. Only file size and compatibility do.

Photos

Terminal
The sips command converts images in place or into a new file.
sips -s format png scan.tiff \
--out scan.pngBuilt into macOS and good for scripts. Run sips --formats to see what your macOS version can read and write.
