Convert TIFF to JPEG — Free Online Converter

TIFF is the professional raster standard supporting uncompressed, LZW, ZIP, and JPEG compression with ICC profiles and 16/32-bit depth. JPEG is the universal photo format using DCT-based lossy compression optimized for photographic content. Converting TIFF to JPEG moves professional images from the production/archival format to the distribution format — typically reducing file size by 10-50x while maintaining excellent visual quality for photographs.

This is the standard production-to-distribution conversion in professional photography, publishing, and medical imaging. Photographers shoot and edit in TIFF (or RAW-to-TIFF) for maximum quality, then convert to JPEG for client delivery, web publishing, portfolio display, and social media sharing.

TIFF files are too large for distribution. A single 4000x6000 photograph in 16-bit TIFF can be 140 MB. The same image at JPEG quality 90 is typically 5-10 MB — a 15-25x reduction. Email attachment limits, web upload constraints, and storage quotas make TIFF impractical for sharing.

JPEG is universally accepted for photograph delivery. Print services, stock photo agencies, social media platforms, and client delivery systems all expect JPEG. Professional workflows maintain TIFF masters for editing and archival, then convert to JPEG for every outward-facing use.

Sharp decodes the TIFF's pixel data (handling LZW, ZIP, JPEG, and uncompressed variants transparently), quantizes 16/32-bit data to 8-bit per channel if needed, flattens alpha transparency against a configurable background, then applies JPEG DCT compression at the specified quality (default 85). ICC color profiles from the TIFF are embedded in the JPEG output when present. Chroma subsampling defaults to 4:2:0.
