Convert Quite OK Image (.qoi) to PNG for free. Choose files, review the available settings and download your results. No account needed.
A compact specification for lossless RGB and RGBA images. QOI focuses on straightforward, fast encoding and decoding with eight bits per channel.
The original pixel values are preserved by QOI encoding itself, but earlier resizing or color conversion can change them.
QOI file format guideLossless raster images with transparency. A good fit for screenshots, diagrams, and graphics.
PNG file format guideChoose dimensions and image quality before converting. Still-image exports keep one frame. Unedited GIF, WebP, AVIF, JPEG XL and MNG conversions can retain animation. Animated edits use a GIF intermediate with a limited color palette. Canvas editing uses browser display precision and does not preserve original EXIF, HDR, or scientific image data.
