Why convert TIFFs to black and white?
Imagine you’re working with a high-resolution TIFF image from a scanner or camera, but the file is so large it slows down your computer or takes ages to upload. TIFFs are great for preserving image quality, but that detail comes at a cost, especially when colour data is involved. Converting your TIFF to black and white can dramatically reduce the file size while keeping all the clarity you need.
You might also need a black-and-white TIFF for printing, archiving, or document management. Many professional scanners and legal or medical systems prefer monochrome TIFFs because they’re cleaner, more consistent, and easier to store and index.
An online file converter makes it simple to turn a full-colour TIFF into a sharp black-and-white image in seconds, saving space, time, and printing costs without compromising on precision. Efficient, right?
