Convert HEIC to TIFF Online — Free

Runs 100% in your browser — your files never leave your device.

TIFF is a practical archival and print target when an editor cannot open an iPhone HEIC file. This tool decodes the HEIC right in your browser and writes a lossless TIFF, keeping the original photo off the network.

How it works

  1. 1

    Drop the HEIC image

    HEIC and HEIF extensions are accepted.

  2. 2

    Convert to lossless TIFF

    The image is decoded and encoded without a server upload.

  3. 3

    Download the TIFF

    Save the browser-generated archival image.

About this tool

Converting HEIC to TIFF

A HEIC file heic is the iphone's native photo format — roughly half the size of jpg at equal quality, with limited support outside apple ecosystems.. TIFF tiff is the archival and print professional's format: lossless, enormous, and built for quality rather than transfer. Converting moves your image from the first set of trade-offs to the second: file size shifts with the format's compression style, transparency is lost, because TIFF cannot carry it, and pixel data is re-mapped to the target format exactly.

What to check after converting

Open the result and check the two things conversion can change: transparency and size. Your HEIC source supported transparency, which TIFF cannot carry — transparent areas typically fill with white or black, so design around a solid background if that matters. Remember the source was already lossy: converting to TIFF preserves what arrived, it cannot restore what earlier compression discarded. Your original file stays untouched on your device either way, and the download is a brand-new file.

Frequently asked questions

Will converting to TIFF improve the quality?

No conversion improves quality that compression already removed — moving HEIC to TIFF preserves what arrived and stops further loss, but the artifacts baked into the source stay baked in. The gains are about features: transparency, compatibility, or editing headroom.

Is my image uploaded anywhere?

No — the conversion runs entirely in your browser. The image is processed on your device and never sent to any server, which you can verify by disconnecting after the page loads.

Why convert HEIC to TIFF instead of the other way around?

The direction follows what the destination needs: archival, scanning, and print workflows versus Apple device storage efficiency. Converting back is always available — but each lossy hop re-encodes the image, so keep the highest-quality format as your working copy and convert toward the destination.
