HEIC to TIFF
Converting a .heic image to .tiff re-encodes the pixels for a different balance of size, quality, and support. Free, private, and validated — the file never leaves your browser.

Converting a .heic image to .tiff re-encodes the pixels for a different balance of size, quality, and support. A .heic file contains imagery compressed with the HEVC (H.265) video codec inside the HEIF container — it is the specific HEVC-coded flavor of HEIF. Apple made it the default camera format on iPhone, so most .heic files people encounter are iPhone photos that roughly halve the storage of equivalent JPEGs.
A .tiff file is a Tagged Image File Format raster, the long-standing archival and prepress standard for images that must not lose a single bit. Its tag-based structure lets one .tiff hold multiple pages, layers of metadata, and pixel formats from 1-bit fax scans to 32-bit floating-point channels. For this route the practical draw is losslessly preserves any bit depth and color space you throw at it and decades of stability make it the safest long-term archival bet — balanced against files are huge — often 10x a visually identical JPEG, which is worth knowing before you commit a large batch.
Why convert HEIC to TIFF?
The practical trigger for this conversion is usually a mismatch: with .heic, hEVC patent licensing means Windows users must install a codec (historically a paid $0.99 extension) to view files. Switching to .tiff buys you losslessly preserves any bit depth and color space you throw at it, which is why it is the better fit for archival masters for museums, libraries, and digitization projects. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
HEIC vs TIFF at a glance
| Aspect | HEIC image (.heic) | TIFF image (.tiff) |
|---|---|---|
| Format type | Lossy — discards detail it judges invisible to shrink files | Lossless — every pixel or sample is preserved exactly |
| How it stores data | pixels are HEVC intra-coded, commonly at 10-bit depth on recent iPhones | structured as Image File Directories (IFDs) of numbered tags, allowing multiple images per file |
| Strongest at | default photo capture on iPhone and iPad, halving camera roll storage | archival masters for museums, libraries, and digitization projects |
| Weak spot | hEVC patent licensing means Windows users must install a codec (historically a paid $0.99 extension) to view files | files are huge — often 10x a visually identical JPEG |
| Metadata | full EXIF (including GPS and orientation) and XMP are carried as container-level metadata items, and Apple additionally embeds depth and gain-map auxiliary data that most converters discard | eXIF is itself structured as TIFF tags, so TIFF holds it natively, alongside XMP packets, IPTC records, ICC profiles, and GeoTIFF georeferencing tags |
Pick TIFF as the output
Select .tiff in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if TIFF is selectable, the route is real and validated.
Convert on your device
Press Convert. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid TIFF file. Outputs keep the original filename with the .tiff extension.
HEIC to TIFF questions, answered
Will converting HEIC to TIFF lose quality?
No new loss is introduced — since heic is lossy-oriented and tiff is lossless-oriented, everything the .heic file still contains is carried over exactly. What was already discarded by the original lossy encode cannot be recovered, though; converting to .tiff does not "restore" quality.
Is it private to convert HEIC files here?
Yes — the .heic file is processed inside your browser tab and never uploaded. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders. Close the tab and the file is gone from memory.
Where will the TIFF file work?
Every serious image editor, scanner driver, and DTP application on Windows, macOS, and Linux reads TIFF, and both major OSes preview it natively. Web browsers are the gap: Chrome, Firefox, and Edge will download rather than display a .tiff, so web delivery always requires conversion to PNG, JPEG, or WebP.
Will the TIFF file be bigger or smaller than my HEIC?
Larger, sometimes much larger. A lossless .tiff must store every pixel or sample the decoder produced, without the perceptual shortcuts .heic used. Use this route for editing headroom, not for saving space.
What happens to the metadata in my HEIC file?
In .heic, full EXIF (including GPS and orientation) and XMP are carried as container-level metadata items, and Apple additionally embeds depth and gain-map auxiliary data that most converters discard. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
