TIFF (Tagged Image File Format) is a flexible raster image format widely used in professional photography, scanning, and print production. TIFF files can store images with or without compression (supporting both lossless LZW and lossy JPEG compression), multiple layers, high bit depths (up to 32-bit per channel), and multiple pages in a single file.
Professional photographers often save RAW processed images as TIFF for archiving because TIFF supports 16-bit color depth (vs JPEG's 8-bit), preserving more color gradation for post-processing. Scanners default to TIFF output. Print workflows use TIFF because it supports CMYK color mode (essential for offset printing), unlike JPEG or PNG which are RGB-only.
TIFF files are very large: an uncompressed 24-bit 4000×6000 TIFF is about 68MB. For web use, always convert TIFF to JPEG or WebP. FileCurve supports converting TIFF to JPG and PNG for web-compatible output.
