Convert HEIC to TIFF — Free Online Converter

HEIC stores iPhone and iPad photos with HEVC compression optimized for mobile storage, while TIFF is the professional standard for print production, archival preservation, and scientific imaging. TIFF supports lossless compression, 16-bit color depth, multiple pages, extensive metadata, and ICC color profile embedding — making it the gold standard for workflows that demand maximum quality and editability.

Converting HEIC to TIFF extracts the full pixel data from Apple's HEVC-compressed images and writes it into TIFF's flexible container with lossless compression. This is the standard conversion for photographers who shoot on iPhone but need to deliver or archive in professional TIFF format.

TIFF is the universal delivery format for professional print production. Offset printing companies, fine art reproduction services, photo labs, and magazine publishers accept TIFF because it guarantees lossless quality with rich metadata. If you shoot product photography, real estate photos, or editorial content on iPhone, converting to TIFF for delivery to print production is standard practice.

TIFF is also the required format for many archival and preservation workflows. Libraries, museums, government archives, and cultural heritage institutions use TIFF for long-term digital preservation because the format specification is well-documented, stable, and supported by decades of tooling. Converting iPhone HEIC photos to TIFF for archival ensures long-term accessibility.

Sharp decodes the HEIC file using its HEVC decoder, converting Apple's Display P3 color to sRGB (or preserving P3 in the ICC profile when specified). The decoded pixel buffer is written as TIFF with configurable compression: LZW (lossless, widely compatible), ZIP/Deflate (lossless, slightly smaller), or no compression. Alpha channel data is preserved as a TIFF extra sample when present. 8-bit output is standard; 16-bit per channel is available for maximum tonal precision.
