Convert iPhone HEIC to TIFF
TIFF is what print shops, archives and prepress workflows still ask for. It is lossless, it has been stable for decades, and unlike HEIC it does not depend on a patented codec being present on the machine that opens it.

Why Convert HEIC to TIFF?
Print labs and publishers specify TIFF because it is predictable: no generation loss, no compression artefacts appearing in a large print, and near-universal support in professional software going back many years.
HEIC needs an HEVC decoder, so a file that opens instantly on an iPhone may show nothing at all on Windows 10, on older Android builds, or in most web forms and email clients. Neither property suits long-term archiving, where the safe assumption is that whatever opens the file in twenty years will be simpler than what exists today.
The cost is size. TIFF stores pixel data with little or no compression, so a 2MB HEIC commonly becomes a 20-40MB TIFF. That is the point — the format is designed for fidelity, not for transfer.

Frequent Questions
Why are my photos suddenly HEIC instead of JPG?
iOS has defaulted to HEIC since iOS 11 to save storage. Settings → Camera → Formats → Most Compatible switches new photos back to JPG; existing ones stay HEIC until converted.
How do I change HEIC to an image file?
HEIC is already an image file — the problem is that fewer programs can read it. Converting to TIFF, JPG or PNG gives you a file that older and professional software will open.
How do I turn a picture into a TIFF file?
Upload it above and select TIFF. Most desktop editors can also export TIFF, but they need to be able to open HEIC first, which is where Windows in particular tends to fail.
Does Windows 11 open HEIC files?
Only after Microsoft's HEIF Image Extensions are installed from the Store. Windows 10 support is less reliable, which is why converting is often simpler than troubleshooting.
Does converting to TIFF improve quality?
No. It preserves what is there without adding anything. What TIFF prevents is further loss — every subsequent save keeps the image identical, which JPG cannot promise.
Why is the TIFF so much bigger?
TIFF applies little or no compression by design, while HEIC uses an efficient modern codec. A ten-to-twentyfold size increase is normal and expected.
