What HEIC to QOI conversion does

Convert a HEIC photo to QOI (Quite OK Image) directly in your browser. QOI is a simple, fast, lossless image format popular in developer and graphics-programming workflows.

How to convert HEIC to QOI

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

Why use this conversion

QOI’s small, easy-to-implement specification makes it popular in tooling and pipelines that specifically read or write QOI, where fast encode/decode matters more than universal support.

Transparency and output quality

QOI supports a full alpha channel, and this tool preserves it from the source. QOI encoding is always lossless — every pixel from the source is reproduced exactly. Resulting file size is typically comparable to PNG.

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.
• QOI is a developer-focused format with limited support in mainstream operating systems and browsers — it is intended for tooling and pipelines that read QOI directly.
• Multi-image HEIC containers — bursts or Live Photos — download as multiple QOI 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 QOI FAQ

Why convert HEIC to QOI?

QOI’s small, easy-to-implement specification makes it popular in tooling and pipelines that specifically read or write QOI, where fast encode/decode matters more than universal support.

Is QOI output lossless?

Yes. QOI encoding is always lossless — every pixel from the source is reproduced exactly.

Does QOI output keep transparency?

Yes. QOI supports a full alpha channel, and this tool preserves it from the source.

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.
