Convert TIFF to GIF — Free Online Converter

TIFF supports up to 32-bit color depth with ICC profiles and professional metadata, while GIF uses LZW compression limited to 256 indexed colors. Converting TIFF to GIF applies aggressive color quantization, reducing the professional color space to a web-friendly 256-color palette. This conversion is appropriate when professional TIFF images need to be shared on the web, in messaging, or in legacy digital contexts where GIF's universal support and small file size are more important than color fidelity.

The most common scenario is extracting simple graphics (charts, diagrams, line art) from professional TIFF files for web distribution. These content types often use fewer than 256 colors naturally, making the quantization invisible. Photographic TIFFs, however, suffer significant quality degradation from the 256-color limit.

GIF provides universal web compatibility at very small file sizes. When TIFF images — particularly charts, diagrams, and simple graphics — need to be shared via email, messaging apps, or legacy web platforms, GIF provides the most universally supported format with the smallest file footprint. The file size reduction from TIFF to GIF can be 20-100x for suitable content.

Legacy systems and older email clients display GIF inline more reliably than many other formats. For sharing professional graphics in environments where compatibility trumps quality, GIF provides the safest format choice.

Sharp decodes the TIFF's pixel data (supporting LZW, ZIP, JPEG, and uncompressed variants), quantizes the full color range to 256 colors using median-cut quantization, and encodes the result as GIF89a with LZW compression. Optional Floyd-Steinberg dithering distributes quantization error. Multi-page TIFFs yield only the first page. 16-bit TIFF data is first quantized to 8-bit before the palette reduction. TIFF transparency is converted to GIF's binary transparency.
