Setup: HEIC is Apple's HEVC-based photo container, half the size of JPEG for the same apparent quality. Goal: an interchangeable TIFF. Need a TIFF for a CMS, a chat message or an email client that politely refuses HEIC? This tool re-encodes your image in the background and returns a drop-in TIFF replacement. No registration, no watermark, no visual change beyond what the TIFF encoder itself introduces. One more beat. HEIC is Apple's HEVC-based photo container, half the size of JPEG for the same apparent quality. Receiving format: TIFF is the archival multi-page master format used in scanning, print and document pipelines.
HEIC Image
Source formatHEIC is the default photo format on Apple devices since iOS 11. It offers roughly 50% better compression than JPEG at similar quality but has limited support outside the Apple ecosystem.
TIFF Image
Target formatTIFF is a flexible, high-quality image format widely used in publishing, printing, and professional photography. It supports multiple compression methods and color spaces including CMYK.
Why convert HEIC to TIFF
Converting keeps the picture recognisable end-to-end while changing the container that ships it. TIFF typically wins on one of three fronts: broader software support, smaller files for the same visual quality, or features like transparency that HEIC cannot express. The conversion itself is fast because both sides are raster formats.
HOW TO CONVERT
HEIC → TIFF
Upload your HEIC
Start by dropping the HEIC onto the uploader. Files up to 100 MB go through on the free tier without registration.
Conversion happens server-side
Our imagemagick-based pipeline reads the HEIC pixel grid, preserves resolution and colour profile, and encodes a clean TIFF.

Common Use Cases
Cross-platform previews
Windows, macOS and Linux file browsers all render TIFF thumbnails; HEIC support varies by OS version.
Mobile galleries
iOS Photos, Google Photos and Samsung Gallery index TIFF instantly — HEIC sometimes falls back to a generic file icon.
Stock photography uploads
Shutterstock, Adobe Stock and similar marketplaces require TIFF in their contributor guidelines.
Archive migration
Converting legacy HEIC archives to TIFF future-proofs the collection against declining codec support.
HEIC vs TIFF — Strengths and limitations
What each format does best, and where it falls short.
HEIC Strengths
- Roughly 50% smaller than JPEG at equivalent visual quality.
- 10- and 12-bit color depth supports HDR photography.
- Container format holds depth, Live Photo, bursts, and thumbnails in one file.
- Supports transparency and multi-image sequences.
- Built into iOS, macOS, and most modern Samsung and Google flagships.
Limitations
- Patent-encumbered (HEVC) — Windows users must buy a $0.99 codec pack from the Microsoft Store.
- Not supported by most web browsers or older image editors.
- Sharing to non-Apple platforms usually auto-converts to JPEG, losing metadata.
TIFF Strengths
- Lossless by default — no generation loss on successive edits and saves.
- Supports any bit depth (1 to 32 bits per channel), any color model, any number of channels.
- Extensible tag system means vendor-specific data survives alongside standard tags.
- Multi-page containers are perfect for scanned documents, faxes, and DICOM-like stacks.
- Industry-standard for archival, museums, scientific imaging, and high-end print prepress.
Limitations
- File sizes are huge compared to JPEG/WebP/AVIF — often 10-30× larger.
- Not a web format — no browser displays TIFF natively.
- Ambiguous spec areas mean some TIFFs only open correctly in the tool that created them.

HEIC vs TIFF — Typical file sizes
Approximate file sizes for common scenarios.
HEIC
- iPhone photo (12 MP) 1.5–3 MB (half of JPEG)
- Live Photo with 3s video 3–6 MB
- Portrait mode with depth map 2–4 MB
TIFF
- Scanned A4 page (300 dpi, B&W) 100-300 KB
- Scanned A4 page (600 dpi, color) 15-40 MB
- Print-quality magazine photo 30-150 MB
- Satellite GeoTIFF tile 50 MB - 5 GB
Quality & Compatibility
Converting keeps resolution, aspect ratio and colour profile identical to the source. Metadata (EXIF, XMP) transfers where TIFF supports it; otherwise it is dropped. If the HEIC contained an alpha channel and TIFF does not support transparency, the background is flattened to white by default.
Tips for Best Results
- When uploading to Retina / high-DPI contexts, render the TIFF at 2× the CSS pixel size; the crispness gap over 1× is noticeable on modern screens.
- Strip EXIF metadata from the TIFF before publishing if the HEIC came from a phone camera — it often contains GPS coordinates and device IDs.
- If the HEIC is a screenshot of text or UI, prefer a lossless TIFF target to avoid the JPEG-style ringing around glyph edges.
Frequently Asked Questions
Frequently Asked Questions
It depends on the codecs involved. If both HEIC and TIFF are lossy, the pixels are re-encoded and a small amount of detail is discarded — invisible at default quality settings on photographs. If TIFF is lossless (PNG, TIFF, BMP) the output keeps every pixel of the decoded HEIC exactly, but cannot recover detail that HEIC had already compressed away.
Often yes, especially when TIFF is lossless. HEIC tuned for efficient web delivery will usually produce smaller files than TIFF's default settings. If file size matters, drop the quality in Advanced or pick a more compressed target format instead.
KaijuConverter uploads over HTTPS, processes the image in an isolated container and deletes both the source and the output within two hours. No account is required, file contents are never logged, and we do not use uploads to train any model. For confidential material, the paid plan includes a data-processing agreement.
