Supports: TIFF, TIF
TIFF (Tagged Image File Format, 1986) is the print, archival, and scanning standard — uncompressed or losslessly compressed, often 30-100 MB per image, universally supported by pro tools but unwieldy on phones. HEIC (Apple's HEIF/HEVC container, 2017) is the modern mobile photo format — typically 1/10 the size at indistinguishable viewing quality, and the native format for iPhone, iPad, Mac, and iCloud Photos. Common reasons to convert TIFF → HEIC:
| Property | TIFF | HEIC |
|---|---|---|
| Compression | Uncompressed or lossless (LZW, DEFLATE, ZSTD, PackBits) | Lossy HEVC (very efficient) |
| File size (12 MP photo) | 30-50 MB | 2-3 MB |
| Bit depth | 1 / 8 / 16 / 32 bit per channel | 8 / 10 bit |
| Color spaces | RGB, CMYK, LAB, grayscale, multi-channel | RGB only |
| Native viewer | Photoshop, GIMP, every pro tool, every print shop | iOS, macOS, Windows 10+ (with HEIF extension), modern Android |
| Year introduced | 1986 | 2017 |
| Best for | Print, archival, professional editing, scanning | Mobile photos, iCloud storage, casual sharing |
| Typical 1,000-image library | ~30-50 GB | ~2-3 GB |
| Preset | Visual quality | Size vs TIFF | Best for |
|---|---|---|---|
| Highest / Very High | Visually identical at 100% zoom | ~5-8% of TIFF | Photo masters, archive replacements you may print again |
| High (default) | Indistinguishable for normal viewing | ~3-5% of TIFF | Phone / tablet libraries, iCloud uploads |
| Medium | Minor softening on close inspection | ~2% of TIFF | Casual photo sharing, social posts |
| Low / Lowest | Visible compression on detailed images | ~1% of TIFF | Tiny previews, contact sheets, low-bandwidth sharing |
Windows 10 / 11 supports HEIC after installing the free HEIF Image Extension from the Microsoft Store (Apple covers the codec license). macOS, iOS, iPadOS, and modern Android (10+) handle HEIC natively. Older Windows 7 / 8 boxes and legacy Linux setups may not — convert to JPG instead with HEIC to JPG if you're sharing with mixed-platform recipients.
For typical 12-24 MP photo TIFFs at LZW compression, expect 90-95% reduction at the High preset. A 35 MB scanned-photo TIFF lands around 1.5-3 MB as HEIC. Higher-detail content (textured fabric, foliage, fine print) compresses slightly less; flat areas like sky or document margins compress more. Setting Highest preset costs maybe 2× more space than High but is closer to lossless visually.
For viewing — yes, at High or above the difference is invisible without pixel-peeping. For archival or future editing — keep your TIFF originals. HEIC is lossy: every save discards perceptual data that can't be recovered, and 10-bit max color depth is below TIFF's 16-bit master headroom. The professional workflow is dual storage: TIFF master archive (cold storage / NAS) + HEIC working copies (phone, tablet, iCloud).
Yes. EXIF metadata (date, camera model, scanner info, copyright tags) and embedded ICC color profiles transfer to the HEIC output. iPhone photo apps and macOS Preview will read the right capture date and color rendering. If you scanned TIFFs without EXIF (common with older scanners), the HEIC inherits whatever the file had — usually just basic dimensions and color profile.
HEIC is RGB-only — there's no CMYK in the HEIF spec. CMYK TIFFs convert by mapping to RGB first; this is fine for screen viewing but not for going back to print. If you need to round-trip a CMYK proof file, keep the TIFF. For a screen-friendly preview that's small enough to email, HEIC works perfectly.
TIFF supports multi-page files (common for fax archives and scanned documents). HEIC is single-image per file. The converter outputs one HEIC per TIFF page, named with a page suffix. If you specifically need a multi-page document format, TIFF to PDF is usually the better target.
Yes — drop in folder-fulls. Each file converts in parallel on our servers (limited only by your CPU and memory) and downloads as a ZIP. For multi-gigabyte archives, the practical limit is upload size and your connection — the limit is your machine's RAM, not network bandwidth.
Yes. Drop the converted HEICs into Photos app on Mac or import via the Photos app on iPhone / iPad and they appear as native HEIC images. Date-taken EXIF determines the photo's place in the timeline, so older scans land in the correct chronological bucket. If you want them in a specific album, create the album first then import.
HEIC if your audience is on Apple devices or modern Windows / Android — you get ~50% smaller files at equal quality. JPG (see TIFF to JPG) if you need universal compatibility (every browser, every email client, every legacy device since the 1990s). HEIC is the better long-term choice; JPG is the safer short-term one.
