Why would I need TIFF instead of HEIC?

Print shops, scanning pipelines, and archival workflows often specifically require TIFF as the master format.

What happens with a multi-image HEIC file?

Every decoded image is kept. A single-image HEIC downloads as one file; 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.

How to Convert HEIC to TIFF in Your Browser

Converting a HEIC or HEIF photo to TIFF produces an uncompressed 8-bit RGBA TIFF suited to print production, scanning, and archival master copies. This guide covers the steps and what to know about transparency and file size.

Step-by-step conversion

Open /tools/heic-to-tiff.
Choose a HEIC or HEIF file — the content is validated before conversion, not just the filename or extension.
Select Convert & download.
Save the .tiff file from your browser downloads.

Transparency and file size

Output is uncompressed 8-bit RGBA, so an alpha channel from the source is preserved. Because the file is uncompressed, it can be several times larger than the source.

Source-specific behavior

HEIC/HEIF containers can hold more than one image (a burst or a Live Photo). A single-image file downloads as one output file; a multi-image file downloads as a ZIP with every decoded image converted, so nothing is silently dropped.

Privacy

Conversion runs locally in your browser. The file is not uploaded to Looty Tools servers for this workflow.
