What HEIC to TIFF conversion does

Convert a HEIC photo to TIFF directly in your browser. TIFF is the standard for print production, scanning, publishing, and archival master copies, where lossless fidelity matters more than file size.

How to convert HEIC to TIFF

1. Choose a HEIC file.
2. Select Convert & download.
3. Save the .tiff file from your browser downloads.

Why use this conversion

Print shops, scanning pipelines, and archival workflows often specifically require TIFF as the master format, since it stores pixel data without lossy compression.

Transparency and output quality

Output is uncompressed 8-bit RGBA, so an alpha channel from the source is preserved. This tool writes uncompressed TIFF (raw RGBA pixel data), so the file can be several times larger than the source.

Privacy and local processing

• Processing occurs locally in the browser.
• Files are not uploaded to Looty Tools for conversion.
• Converted files remain on your device.

Limits and known issues

• Input: HEIC/HEIF (.heic, .heif) only, up to 25.0 MB and 8,192 px per side.
• This is a standard baseline uncompressed TIFF. Software expecting a specific compressed TIFF variant (LZW, ZIP) should still be able to open it, since compression is optional in the TIFF spec.
• Multi-image HEIC containers — bursts or Live Photos — download as multiple TIFF files, or a ZIP when there is more than one. Every decoded image is kept; none are silently discarded.
• Metadata is not preserved in the downloaded file.

HEIC to TIFF FAQ

Why convert HEIC to TIFF?

Print shops, scanning pipelines, and archival workflows often specifically require TIFF as the master format, since it stores pixel data without lossy compression.

Does TIFF output keep transparency?

Yes. Output is uncompressed 8-bit RGBA, so an alpha channel from the source is preserved.

Why is the TIFF file so much larger than the source?

This tool writes uncompressed TIFF (raw RGBA pixel data) rather than a compressed variant, which is a deliberate tradeoff for fidelity in print, scanning, and archival workflows.

What happens with a multi-image HEIC file?

Every decoded image is kept — a single-image HEIC downloads as one file, and a multi-image HEIC (a burst or Live Photo) downloads as a ZIP containing every decoded image, never just the first one.

Are my files uploaded?

No. Conversion runs locally in your browser and does not upload your file to Looty Tools servers.

What is validated before conversion?

The file must actually be a HEIC/HEIF container — the tool checks the ISO-BMFF ftyp brand, not just the filename or extension, before decoding.
