HEIC to QOI Converter
Convert HEIC and HEIF photos to QOI (Quite OK Image), a fast, lossless, developer-focused format, directly in your browser.
HEIC to QOI processes files locally in your browser.
What HEIC to QOI conversion does
Convert a HEIC photo from your iPhone into QOI (Quite OK Image) directly in your browser. QOI decodes and re-encodes losslessly with a tiny, simple spec, which is exactly what developer and graphics-programming tooling wants instead of parsing Apple's more complex HEIC/HEVC container.
How to convert HEIC to QOI
- Choose a HEIC file.
- Select Convert & download.
- Save the .qoi file from your browser downloads.
Why use this conversion
QOI's small, easy-to-implement specification makes it popular in pipelines that specifically read or write QOI directly, avoiding the heavier HEVC decoding that a HEIC file requires and letting fast, minimal tooling handle the image instead.
Transparency and output quality
QOI supports a full alpha channel, and this tool preserves whatever alpha the decoded HEIC image carries. QOI encoding is always lossless — every pixel decoded from the source HEIC is reproduced exactly, though it can't recover any detail HEIC's own lossy HEVC compression already discarded. 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's intended for tooling and pipelines that read QOI directly, not as a general HEIC replacement for everyday viewing.
- A multi-image HEIC — a burst or Live Photo — produces one QOI file per captured frame, delivered as a ZIP when there's more than one; every decoded image is kept.
- 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 pipelines that specifically read or write QOI directly, avoiding the heavier HEVC decoding a HEIC file requires and letting fast, minimal tooling handle the image instead.
- Is QOI output lossless?
- Yes. QOI encoding is always lossless — every pixel decoded from the source HEIC is reproduced exactly, though it can't recover detail HEIC's own lossy HEVC compression already discarded.
- Does QOI output keep transparency?
- Yes. QOI supports a full alpha channel, and this tool preserves whatever alpha the decoded HEIC image carries.
- What happens with a multi-image HEIC file?
- Each image inside a multi-image HEIC — a burst or Live Photo — becomes its own QOI file. A single-photo HEIC downloads one .qoi; a burst or Live Photo downloads a ZIP with one QOI per captured 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.
