TIFF File Format (Tagged Image File Format)
TIFF is a flexible, high-quality raster image format used primarily in professional photography, publishing, and medical imaging. Developed by Aldus (later acquired by Adobe) in 1986, TIFF supports multiple pages, layers, various compression methods, and high bit depths up to 32-bit per channel. TIFF files can store images in virtually any color space including RGB, CMYK, Lab, and spot colors, making them the standard format for prepress and print workflows. The format uses a tag-based structure that allows arbitrary metadata and extensions. While TIFF produces large files, its lossless quality and flexibility make it essential for professional image archival and high-end publishing.

- Medical and scientific imaging (pathology, satellite)
- Scanned document archival
- GIS and geospatial data (GeoTIFF)
Technical Details
TIFF uses an Image File Directory (IFD) structure where each IFD entry is a tag with a type, count, and value. Tags define image dimensions, bit depth, compression, color space, strip offsets, and tile layout. TIFF supports tiled storage for efficient random access to large images. Compression options include no compression, LZW, ZIP/Deflate, JPEG (lossy), PackBits, and CCITT Group 3/4 for fax. BigTIFF extends the format beyond the 4 GB file size limit of classic TIFF by using 64-bit offsets.
Frequently Asked Questions about TIFF
When should I use TIFF?
Use TIFF for professional print work, archival photography, medical imaging, or any workflow where lossless quality and high bit depth are required. For web and screen use, PNG or WebP are more practical.
Can browsers display TIFF images?
No. Major web browsers do not natively support TIFF. Convert to JPG, PNG, or WebP for web display.
Is TIFF better than PNG for lossless storage?
TIFF supports higher bit depths, CMYK color, and multi-page documents. PNG is better for web use and simpler workflows. Both are lossless.
Why is my TIFF file so large?
TIFF files with no compression or LZW compression on high-resolution, high-bit-depth images can be very large. Consider using ZIP compression within TIFF, or convert to a smaller format for sharing.
