Frequently Asked Questions
- Does HEIF to TIFF preserve 10-bit color?
- Yes. 10-bit HEIF from Sony, Canon, and Samsung is decoded to 16-bit internally and written as a 16-bit TIFF. The full 10-bit precision is preserved with 6 bits of additional headroom for editing.
- Why is the TIFF so much larger than the HEIF?
- HEIF uses HEVC lossy compression — roughly 2× more efficient than JPEG. TIFF stores decoded pixels losslessly. A 3 MB HEIF may become 15–30 MB as 8-bit TIFF or 30–60 MB as 16-bit TIFF. This is the expected cost of lossless archival storage.
- Does HEIF to TIFF preserve HDR?
- Partially. Convertify tone-maps HLG/PQ HDR content to SDR sRGB for standard TIFF output. 16-bit TIFF retains more of the tonal range than 8-bit alternatives. Full HDR preservation would require HDR-aware TIFF workflows that most software does not support.
- Does Convertify handle both .heif and .heic files?
- Yes. libvips registers its HEIF loader for .heif, .heic, .HIF, and .avif. libheif detects the codec inside automatically regardless of file extension.
- Which TIFF bit depth should I choose?
- 16-bit for 10-bit HEIF sources (Sony, Canon) — preserves full color precision for editing. 8-bit for standard 8-bit HEIF (Samsung default mode) — avoids unnecessary file size doubling.
- Does the conversion preserve EXIF and GPS metadata?
- Yes by default. GPS coordinates, capture time, camera model, lens info, and exposure settings all transfer to the TIFF. Use the strip option to remove metadata for privacy.
- Can I batch convert HEIF to TIFF?
- Yes. Upload up to 10 files and download them all as TIFF simultaneously.
- Can browsers display TIFF?
- No. TIFF has zero browser support in Chrome, Firefox, and Edge. For web delivery, convert to WebP or AVIF instead.
Why HEIF to TIFF matters for 10-bit camera files
Sony Alpha cameras (A7S III, A1, A7R V) shoot HEIF at 10-bit 4:2:0 or 4:2:2 with BT.2020 wide gamut. Canon (EOS-1D X Mark III, R5, R6 II) records 10-bit HEIF with HDR PQ. Samsung Galaxy phones use HEVC encoding inside the HEIF container. All of these cameras produce files with tonal precision that 8-bit formats like JPG cannot store.
Converting to 16-bit TIFF is recommended for preserving this precision. libvips decodes the 10-bit HEIF data into a 16-bit internal representation (VIPS_FORMAT_USHORT), and vips_tiffsave writes the full 16-bit values. The extra 6 bits of headroom above the source 10-bit data give editing applications room for aggressive color grading without introducing banding artifacts.
HDR HEIF: tone mapping for TIFF
HEIF files from Sony HLG Still Image mode and Canon HDR PQ mode encode images with high dynamic range transfer functions. TIFF does not have a standardized HDR container for typical workflows — the vast majority of TIFF readers assume SDR gamma.
Convertify performs sRGB tone mapping on HDR HEIF before writing the TIFF: the HLG or PQ transfer curve is applied, BT.2020 primaries are converted to sRGB via ICC transform, and the resulting sRGB image is written to the TIFF with an embedded sRGB ICC profile. The output looks correct on standard displays but the extended dynamic range above SDR white is compressed into the sRGB range.
For workflows that need HDR preservation, 16-bit TIFF with a linear-light or wide-gamut profile retains more of the original tonal range than 8-bit alternatives like JPG.
Which devices produce .heif files
Samsung Galaxy (S10 through S25 lineup) — opt-in High Efficiency Pictures toggle in Camera Settings, codec HEVC inside HEIF container. The file extension varies by One UI version: some produce .heif, some .heic.
Sony Alpha (A7S III, A1, A7R V) — .HIF extension, 10-bit 4:2:0 or 4:2:2, HLG Still Image mode with BT.2020. Canon (EOS-1D X Mark III, R5, R6 II) — .HIF extension, 10-bit HDR PQ available.
Windows 11 Camera app — writes HEIF when HEIF Image Extension and HEVC Video Extension are installed. Google Pixel — platform-level HEIF support since Android P, codec HEVC.
For Apple .heic files specifically, use the HEIC to TIFF converter — identical pipeline, different landing page optimized for iPhone users.
File size: HEIF vs TIFF
HEIF uses HEVC lossy compression — files are roughly half the size of equivalent-quality JPEGs and dramatically smaller than TIFF. A 3 MB Samsung HEIF photo may become 15–30 MB as an 8-bit TIFF with LZW compression, or 30–60 MB as a 16-bit TIFF. The increase is expected: TIFF stores decoded pixel data losslessly, while HEIF achieves its small size through aggressive perceptual compression.
This size growth is the deliberate trade-off for editing headroom. The 16-bit TIFF master can be color-corrected, white-balanced, cropped, and re-saved unlimited times without accumulating compression artifacts. Once editing is complete, export to JPG or WebP for delivery.
Color profiles and metadata preservation
libvips reads ICC color profiles from HEIF via libheif — including the NCLX (CICP) color signaling used by Sony and Canon for BT.2020 and HLG content. The profile is attached to the VipsImage and written to the TIFF as a standard ICC profile tag.
EXIF metadata is fully preserved: GPS coordinates, capture time, camera make and model, lens information, exposure settings, and ISO values all transfer from the HEIF source to the TIFF output. For privacy-sensitive workflows, metadata can be stripped on request.
How Convertify converts HEIF to TIFF
The Rust backend calls vips_heifload() which passes the file to libheif for codec detection. HEVC-coded HEIF is decoded via libde265; AVC-coded HEIF via OpenH264; AV1-coded HEIF (rare in camera output) via libaom or dav1d. The decoded VipsImage carries 16-bit data for 10-bit sources.
vips_tiffsave() writes the output with LZW compression, the original ICC profile, and preserved EXIF metadata. For HDR content, vips_icc_transform applies the BT.2020-to-sRGB conversion before encoding. 16-bit output is the default for 10-bit HEIF sources; 8-bit output is used for 8-bit HEIF to avoid unnecessary file size increase.
