Question 1

Why are TIFF files so large?

Accepted Answer

TIFF files are typically uncompressed or use lossless compression, preserving every pixel without quality loss. A 4000×3000 CMYK image at 32-bit depth is ~48MB uncompressed. This is by design — print and medical professionals need perfect quality.

Question 2

What is the difference between RGB and CMYK TIFF?

Accepted Answer

RGB (Red, Green, Blue) is for screen display. CMYK (Cyan, Magenta, Yellow, Key/Black) is for print. Our CMYK TIFF files let you test that your application correctly handles the 4-channel color space used in professional printing.

Question 3

Can browsers display TIFF files?

Accepted Answer

Safari supports TIFF natively. Chrome, Firefox, and Edge do not display TIFF inline — they trigger a download. For web display, convert to JPG/PNG/WebP. TIFF is primarily for professional workflows, not web viewing.

Question 4

What tools open TIFF files?

Accepted Answer

Adobe Photoshop, GIMP (free), IrfanView (free), LibreOffice Draw, macOS Preview, and Windows Photos. Programmatically: sharp (Node.js), Pillow (Python), LibTIFF (C).
