Convert ARW to TIFF — Free Online Converter

TIFF (Tagged Image File Format) is the professional standard for high-quality image archival and print production. Converting Sony ARW RAW files to TIFF produces an uncompressed or losslessly compressed image that preserves the full quality of the demosaiced sensor data. TIFF is universally supported by professional imaging software including Photoshop, Lightroom, Capture One, Phase One, and every commercial print RIP system.

For Sony Alpha photographers working with high-resolution sensors — the 42 MP A7R III, the 61 MP A7R V, the 50 MP A1 — TIFF provides the highest-quality output format for delivering processed images to print labs, publishers, and archival systems. Unlike JPEG, TIFF supports 16-bit per channel color depth, preserving more of Sony's 14-bit sensor dynamic range. Unlike PSD, TIFF is an open standard supported by every imaging application.

TIFF is the gold standard for professional image delivery. Fine art print labs, book publishers, magazine editorial teams, and museum archival systems all specify TIFF as their preferred or required input format. When a Sony Alpha photographer needs to deliver the highest possible quality to a professional client or institution, TIFF is the format that meets industry specifications.

The 16-bit per channel option is particularly valuable for Sony cameras. The A7R V's 14-bit sensor captures over 16,000 tonal levels per channel. An 8-bit JPEG compresses this to just 256 levels, losing significant shadow and highlight detail. A 16-bit TIFF preserves 65,536 levels per channel, capturing essentially all of the sensor's dynamic range. This matters for images that will undergo further processing, such as fine art printing where shadow detail and smooth gradients are critical.
