Format Details
QOI
QOI (Quite OK Image) is a fast, simple lossless image format designed as a speed-optimized alternative to PNG. It encodes and decodes images in a single linear pass with extremely simple logic, often achieving faster encoding than PNG while producing comparable file sizes. QOI is gaining adoption in game development, real-time graphics, and embedded systems where encoding speed matters as much as compression ratio.
imageJPEG
JPG is the most common file extension for the JPEG image format, which uses lossy compression to significantly reduce file sizes while maintaining visually acceptable quality. Every digital camera, smartphone, and web browser supports JPG natively, making it the dominant format for sharing photographs worldwide. Its excellent balance between file size and image quality has kept it the most-used image format for decades.
imageConverting QOI to JPG: what actually changes
QOI to JPEG is one of the conversions this site performs, but the two formats are not interchangeable containers. Here is what the file keeps, what it loses, and how to get a result you can use.
What .QOI and .JPG each hold
.QOI is a image format built for sharing, editing or publishing a picture, storing pixels, dimensions and colour depth. .JPG is a image format built for sharing, editing or publishing a picture, storing pixels, dimensions and colour depth. Converting between them is a decision about which of those two jobs the result needs to do.
What changes in the conversion
Both files belong to the image category, so this is a like-for-like repackage: the same kind of content, stored in a different container. What changes is how .JPG encodes pixels, dimensions and colour depth — not what the file is about.
When this conversion is the right one
Reach for .JPG when the software, device or platform you are sending to expects it — the content is the same image, only the packaging differs. The reverse direction works the same way, so you can always convert back from .JPG to .QOI using the same tool.
Tips for a clean QOI to JPG conversion
Start from the original file
Convert the .QOI you started with, not an earlier .JPG output. Every extra round trip costs quality and can accumulate formatting drift.
Check the real type, not the extension
Image/x-qoi becomes image/jpeg. If a file was renamed rather than converted, it will fail to open — rename it back to its true extension before uploading and the conversion will recognise it.
Watch transparency and animation
If the .QOI has a transparent background or animation, confirm .JPG supports it. Where it does not, the background is flattened onto a solid colour and only the first frame survives.
Limits worth knowing
Uploads are capped per file (30 MB, or 100 MB for video) and processed temporarily — nothing is kept as a permanent copy. For huge image files, split or compress the source first.
