Convert image files with our easy-to-use and free tool. Our tool lets you upload a QOI (Quite OK Image Format) file and, from this, create a new image saved in the TIFF (Tag Image File Format) format that you can then download and edit within image file editors or use for high-definition printing applications. Our conversion tool can also batch convert multiple QOI image files; up to 25 files at a time can be converted.
Along with converting QOI image files to TIFF, our tool allows you to also adjust the image with some simple effects, such as applying a grayscale filter to the image. These additional options are available within the Options tab. Along with grayscale, you can also mirror or flip the image if needed. For single QOI file uploads, you will also see options to resize and rotate your image.
This option can be used to rotate the image in 90° increments.
When selected, this option will flip the image vertically.
When selected, this option will mirror the image horizontally.
When checked, this will apply a grayscale filter to the image, turning any color image into a grayscale image.
When checked, this will apply a negative filter to the image, inverting all the colors within the image.

The QOI file format is a modern image format capable of storing full color (32-bit) images in a compact format, with file sizes of QOI files similar to those of a PNG file.
QOI files are designed first and foremost with encoding and decoding speed in mind. It is many times faster to encode or decode an image into the QOI format than other formats, such as PNG.

The TIFF file extension is a raster graphics file format originally created in 1986, making it one of the older image file formats available. The format was created by Aldus Corporation (now Adobe) for use in desktop publishing software and is still a popular format that is still in use today.
The format has evolved over time from its original use in DTP applications, fax machine software, optical character recognition software, and more. TIFF files are binary and can contain one or more images arranged in a rectangular data format within the file.
First click the "Upload..." button, select your QOI file to upload. Select any configuration options. When the QOI to TIFF conversion has completed, you can download your TIFF file straight away.
We aim to process all QOI to TIFF conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.
We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.
