How to convert QOI to JPG:
1. Click "Choose Files" button to select multiple files on your computer or click the dropdown button to choose online file from URL, Google Drive or Dropbox. Image file size can be up to 200M. You can use file analyzer to get source image's detailed information such as image size, resolution, quality and transparent color etc.
2. Set target image format, image quality and image size. You can use the original image size or select "Change width and height" option and enter customized image size. The format is [width]x[height], for example: 1920x1080. Image quality option only works on a few image formats such as JPG, WEBP or AVIF etc. The value ranges from 1 (lowest image quality and highest compression) to 100 (best quality but least effective compression). If this value is blank, the converter will use the estimated quality of your input image if it can be determined, otherwise 92. The target image format can be JPG, PNG, TIFF, GIF, HEIC, BMP, PS, PSD, WEBP, TGA, DDS, EXR, J2K, PNM or SVG etc.

|Introduction||QOI - The "Quite OK Image Format" for fast, lossless image compression. QOI is fast. It losslessy compresses images to a similar size of PNG, while offering 20x-50x faster encoding and 3x-4x faster decoding. QOI is simple. The reference en-/decoder fits in about 300 lines of C. The file format specification is a single page PDF.||JPEG is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality.|
|Technical details||A QOI file consists of a 14-byte header, followed by any number of data chunks and an 8-byte end marker. The colorspace and channel fields are purely informative. They do not change the way data chunks are encoded.||Image files that employ JPEG compression are commonly called "JPEG files", and are stored in variants of the JIF image format. Most image capture devices (such as digital cameras) that output JPEG are actually creating files in the Exif format, the format that the camera industry has standardized on for metadata interchange.|
