Convert TIFF to HEIC Online

TIFF files are the professional standard for scanned documents, medical imaging, satellite imagery, and publishing workflows. They preserve every pixel at full depth (often 16 bits per channel) and can be very large - A scanned A4 page at 600 DPI as TIFF is typically 50–150 MB. Converting to HEIC reduces this to a few megabytes, thanks to HEVC compression that is roughly twice as efficient as JPEG.

HEIC is an unusually good target for high-quality TIFF masters because it supports 10-bit colour - Where a JPG export would crush 16-bit tonal data down to 8 bits, HEIC retains substantially more of the original tonal range. That makes TIFF→HEIC attractive for personal archives of scans and edited photographs where storage matters but quality should degrade as little as possible.

Multi-page TIFFs (used for multi-page scanned documents) require special handling. Each page can be extracted as a separate HEIC, similar to converting a multi-page PDF. As always with HEIC, verify the destination: Apple devices and modern Adobe tools open it natively, but legacy publishing systems and Windows without the HEVC codec will not.

TIFF (Tagged Image File Format) was created in 1986 by Aldus Corporation (later merged into Adobe) to standardize scanner output for desktop publishing on PageMaker. Its tag-based container could embed multiple resolutions, color spaces, ICC profiles, and even vector annotations, which made it the default deliverable for print shops, medical imaging (DICOM extensions), GIS, and museum archives. Adobe still publishes the TIFF 6.0 specification (1992) unchanged. TIFF remains the gold-standard archival raster format, but its multi-megabyte files are hopeless on mobile devices — converting derivatives to HEIC keeps 10-bit tonal depth while cutting size by 95 percent or more.

Older raster formats are storage-hungry: BMP stores pixels uncompressed, TIFF archives routinely run 50–200 MB per scan, and even GIF is inefficient by modern standards. Converting these to HEIC collapses the files to a small fraction of their original size while keeping the visual content intact - Often a 90%+ reduction for BMP and uncompressed TIFF sources.

The typical use case is archive modernisation on Apple hardware: folders of legacy scans, exported frames, and old graphics converted to HEIC take up far less space on a Mac or in iCloud, and open natively in Preview, Photos, and Quick Look without any extra software.

HEIC encoding is lossy by default, so keep the original files when they serve as archival masters - Particularly lossless TIFF scans of documents or artwork. For everyday reference copies and personal archives, the space savings usually outweigh the invisible quality trade.
