Frequently Asked Questions
- How much smaller will my HEIC be compared to TIFF?
- Typically 95–98% smaller. A 96 MB TIFF typically converts to approximately 2 MB HEIC. The exact ratio depends on image content.
- Is HEIC supported on all devices?
- HEIC is native on iOS 11+ and macOS High Sierra+. Windows 11 supports it natively; Windows 10 requires the HEVC codec extension. Android and non-Apple browsers do not support HEIC natively.
- Does converting TIFF to HEIC reduce quality?
- HEIC uses lossy HEVC compression. Quality loss at standard settings is imperceptible in photographs. Convertify converts at high quality by default.
- Can I open HEIC files in Photoshop?
- Yes. Adobe Photoshop has supported HEIC since CC 2018. Camera Raw and Lightroom Classic also read HEIC files.
- Why is HEIC not supported in browsers?
- Only Safari 17.6+ renders HEIC natively. Chrome, Firefox, and Edge do not support it. For web delivery, use WebP or JPG instead.
- Does HEIC preserve the color quality of 16-bit TIFFs?
- HEIC supports 10-bit per channel — better than JPEG's 8-bit, but less than TIFF's 16-bit. The difference is imperceptible on standard displays.
- Can I convert multiple TIFF files to HEIC at once?
- Yes. Convertify supports batch conversion — upload up to 10 TIFF files and download them all as HEIC simultaneously.
Why convert TIFF to HEIC?
TIFF files are enormous — a 24-megapixel professional photo weighs 36–144 MB — and have zero browser support. HEIC (High Efficiency Image Coding) uses HEVC compression to produce files roughly 50% smaller than JPEG at equivalent quality, meaning a TIFF-to-HEIC conversion achieves 95–98% size reduction. If your workflow involves Apple devices — importing professional photos into Apple Photos, storing in iCloud Photo Library, or preparing images for iOS/macOS apps — HEIC is the natural target format. It is natively supported on every Apple device running iOS 11+ and macOS High Sierra (2017) or later.
TIFF vs HEIC comparison
| Feature | TIFF | HEIC |
|---|---|---|
| Typical file size (24MP) | 36–144 MB | 2–5 MB |
| File size reduction | Baseline | 95–98% smaller |
| Browser support | None | Safari 17.6+ only |
| Apple device support | Limited | Native (iOS 11+, macOS High Sierra+) |
| Windows support | Full | Requires HEVC codec (free on Win 11) |
| Color depth | 8, 16, 32-bit float | 10-bit (HDR capable) |
| CMYK | Supported | Not supported |
| Compression | Lossless | Lossy (HEVC) |

File size: how much smaller is HEIC vs TIFF
The compression ratio from TIFF to HEIC is among the most dramatic in image conversion. A documented real-world test showed a 96 MB TIFF converting to a 2 MB HEIC — 98% smaller. For a standard 24-megapixel professional photo: uncompressed TIFF at 72 MB (8-bit) or 144 MB (16-bit) versus HEIC at roughly 2–5 MB depending on image complexity. HEIC achieves roughly 50% better compression than JPEG, and JPEG itself is 90–95% smaller than an equivalent TIFF. The chain of compression efficiency: TIFF (largest) → JPEG → HEIC (smallest lossy format with full color quality). This makes TIFF-to-HEIC particularly useful for storage-constrained Apple devices managing large photo libraries.
HEIC in the Apple ecosystem
Apple adopted HEIC as the default iPhone camera format in iOS 11 (2017), replacing JPEG for standard photo capture. The decision reduced iCloud Photo Library storage requirements by roughly 50% compared to equivalent JPEG files. HEIC integrates natively with Photos.app on iOS and macOS, iCloud Photo Library, Airdrop, and the Mac file system. Converting TIFF files to HEIC allows professional photos to blend into an Apple photo library without visual distinction — same format as iPhone photos, same metadata handling, same iCloud sync behavior. Photoshop saved TIFF files converted to HEIC and imported into Apple Photos are treated identically to camera-captured HEIC images.
HEIC platform support outside Apple
HEIC's cross-platform support is limited compared to JPG, PNG, or WebP. Windows 11 supports HEIC natively. Windows 10 requires the HEVC Video Extensions from the Microsoft Store — free in some builds, $0.99 in others. Android has no native HEIC support. Browser support covers only Safari (17.6+); Chrome, Firefox, and Edge do not display HEIC natively. This platform gap is why TIFF-to-HEIC conversion is specifically for Apple-centric workflows: if your images need to work across Android, Windows browsers, or non-Apple software, JPG or WebP are better targets.
TIFF's 16-bit depth vs HEIC's 10-bit
Professional TIFFs from Lightroom and Capture One are typically 16-bit per channel — 65,536 tonal values, providing maximum editing headroom. HEIC supports 10-bit per channel — 1,024 tonal values — and HDR content through the HDR10 and HLG formats. Converting a 16-bit TIFF to HEIC permanently downsamples from 16-bit to 10-bit, though this is imperceptible on standard displays. HEIC's 10-bit depth exceeds standard JPEG's 8-bit, making it a better-than-JPEG choice even when coming from 16-bit TIFFs. Apple's ProRes RAW and Log workflows use 10-bit HEIC for master frame delivery.
Using TIFF to HEIC for iCloud storage management
iCloud Photo Library charges for storage: 50 GB ($0.99/month), 200 GB ($2.99/month), and 2 TB ($9.99/month). Professional photographers who shoot TIFF or store processed TIFFs in Apple Photos quickly exhaust these limits — a single session of 100 images at 36 MB each is 3.6 GB. Converting processed TIFFs to HEIC before import reduces this footprint by 95–98%. The 2 TB iCloud tier can hold roughly 1 million high-quality HEIC photos versus around 50,000 full-resolution TIFFs. For active photo libraries that don't require future re-editing from the master, HEIC is the practical storage solution.
How Convertify converts TIFF to HEIC
Convertify uses a Rust backend with libvips and libheif for TIFF to HEIC conversion. libvips handles TIFF decoding via its streaming pipeline; libheif handles HEIC encoding using HEVC. Color profiles are preserved during conversion. Files are processed server-side over HTTPS and deleted immediately after download. No account required.
