HOW TO CONVERT HEIC → TIFF
Upload your HEIC
Start by dropping the HEIC onto the uploader. Files up to 25 MB go through on the free tier without registration; paid plans go up to 2 GB.
Conversion happens server-side
Our imagemagick-based pipeline reads the HEIC pixel grid, preserves resolution and colour profile, and encodes a clean TIFF.

HEIC uses HEVC (H.265) intra-frame compression to store photographs, which typically cuts file size roughly in half compared to JPEG at equivalent visual quality. That efficiency comes from a lossy codec designed for display pipelines — not archival or print workflows. TIFF, by contrast, is a container format that supports lossless or uncompressed storage, full 16-bit-per-channel depth, CMYK color spaces, embedded ICC profiles, and multi-page sequences. The conversion from HEIC to TIFF is almost always driven by one of three needs: sending files to an application that has no HEIC decoder (most non-Apple desktop software before 2022), preparing images for a print production chain that requires CMYK or demands a lossless source, or creating an archival copy that does not depend on HEVC patent licensing or Apple-specific codec support. Once an image is committed to HEIC, the pixel data has already passed through the lossy HEVC encoder, so converting to TIFF produces a lossless container holding data that was already lossy — the TIFF itself introduces no further generation loss, but it cannot recover what HEVC discarded at capture time.
Why convert HEIC to TIFF
The dominant reason is application compatibility. Windows Photo Viewer, most Linux image editors, older versions of Photoshop, virtually all prepress RIP engines, and many web CMS platforms cannot open HEIC natively. TIFF is one of the oldest and most universally decoded formats in existence — any software that handles raster images reads it. A secondary driver is 16-bit color depth: HEIC on iPhone can store HDR content using HEVC Main 10 profile at 10 bits per channel, and a TIFF conversion preserving 16-bit depth lets you retain that dynamic range headroom for further editing in Lightroom, Affinity Photo, or GIMP without clipping highlights into 8-bit.

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.
Quality & Compatibility
No pixel-level quality is lost during the TIFF encoding step itself, because TIFF with LZW or uncompressed storage is lossless. However, HEIC's HEVC lossy compression has already permanently discarded high-frequency detail before conversion begins. Color space is preserved faithfully if the HEIC's embedded Display P3 or sRGB ICC profile is read and written into the TIFF ICC metadata chunk — without that step the image may appear desaturated in applications that assume sRGB. Transparency (alpha channel) in HEIC files is supported by HEVC Main Still Picture and will be preserved in TIFF as a standard alpha channel. EXIF and XMP metadata blocks embedded in the HEIC container are carried over into the TIFF's metadata fields. The resulting TIFF will be substantially larger: a 12 MP HEIC at 3–4 MB typically expands to 35–70 MB uncompressed TIFF, or 20–40 MB with LZW compression.
Tips for Best Results
- If your HEIC was shot in HDR on an iPhone 12 or later, choose 16-bit TIFF output to preserve the full 10-bit-per-channel dynamic range — an 8-bit TIFF will clip highlights and crush shadows irreversibly.
- Check whether your destination application expects an ICC profile before sending the TIFF: HEIC files from iPhones commonly use Display P3, which has a wider gamut than sRGB, and importing a Display P3 TIFF into software that ignores embedded profiles will make colors look oversaturated or shifted.
- For print workflows, confirm your prepress software can handle RGB TIFF before converting — TIFF supports CMYK, but kaijuconverter outputs RGB TIFF, so a separate color-space conversion step in a color-managed application is required before sending to a CMYK print pipeline.
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.
