Why convert GIF to QOI?

Mainly for developer tooling and pipelines that read QOI directly and want a fast, lossless single image — QOI has no frame or timing structure, so this naturally produces one still from the GIF's first frame.

Does QOI output keep transparency?

Yes. QOI supports a full alpha channel and this tool preserves the alpha from the GIF's first frame exactly, though that alpha was already a hard on/off mask in the source.

Does this keep the GIF's animation?

No. QOI has no format for multiple frames or timing at all, so only the GIF's first frame is encoded — everything else in an animated source is discarded before the file is written.

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 GIF — the tool checks the GIF87a/GIF89a signature bytes, not just the filename or extension, before decoding.

What GIF to QOI conversion does

Convert a GIF to QOI (Quite OK Image) directly in your browser. QOI is a simple, fast, lossless image format popular in developer and graphics-programming workflows — since QOI has no concept of multiple frames, only the GIF's first frame is ever encoded.

How to convert GIF to QOI

Choose a GIF 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, where fast encode/decode of a single still image matters more than universal support or animation.

Transparency and output quality

QOI supports a full alpha channel, and this tool preserves the alpha from the GIF's first frame exactly — since that alpha was already a hard 1-bit mask, QOI is losslessly storing the same binary transparency, not adding anything softer. QOI encoding is always lossless — every pixel from the GIF's first frame 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: GIF (.gif) 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.
QOI has no frame or timing structure of its own, and this tool only ever encodes the GIF's first frame — an animated source loses every later frame and its loop in the conversion, with no way to recover them from the QOI file.
Metadata is not preserved in the downloaded file.
