TIFF to QOI Converter
Convert TIFF images to QOI (Quite OK Image), a fast, lossless, developer-focused format, directly in your browser.
TIFF to QOI processes files locally in your browser.
What TIFF to QOI conversion does
Convert a TIFF image to QOI (Quite OK Image) directly in your browser. QOI is a simple, fast, lossless image format popular in developer and graphics-programming workflows — a fitting modern home for an archival TIFF page that needs to move into a lossless dev pipeline.
How to convert TIFF to QOI
- Choose a TIFF or TIF 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 tooling and pipelines that specifically read or write QOI. Converting an archival or scanned TIFF page to QOI keeps every pixel lossless while shedding TIFF's more complex container.
Transparency and output quality
QOI supports a full alpha channel, and this tool preserves it from the source TIFF page when present (TIFF can carry alpha via its ExtraSamples tag). QOI encoding is always lossless — every pixel from the decoded TIFF page 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: TIFF (.tif, .tiff) 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.
- A multi-page TIFF is treated as if it were single-page here: page one becomes the QOI file, and later pages are silently skipped.
- Metadata is not preserved in the downloaded file.

TIFF to QOI FAQ
- Why convert TIFF to QOI?
- QOI's small, easy-to-implement spec makes it popular in tooling that reads or writes QOI directly. Converting an archival or scanned TIFF page to QOI keeps every pixel lossless while trading TIFF's more complex container for a format built for fast encode/decode.
- Is QOI output lossless?
- Yes. QOI encoding is always lossless — every pixel from the decoded TIFF page is reproduced exactly.
- Does QOI output keep transparency?
- Yes. QOI supports a full alpha channel, and this tool preserves it from the source TIFF page when present.
- Does this convert every page of a multi-page TIFF?
- No. Page one of the TIFF is what gets encoded to QOI — the rest of a multi-page document is not processed.
- 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 TIFF — the tool checks the byte-order header (little-endian "II*" or big-endian "MM*"), not just the filename or extension, before decoding.
