Convert image files with our easy to use and free tool. Our tool lets you upload a FAX (Group 3 FAX) file and from this, create a new image saved in the AVIF (AV1 Image File Format) format that you can then download and edit/use within image file editors or use for high definition printing applications. Our conversion tool can also batch convert multiple FAX image files, up to 25 files at a time can be converted.
Along with converting FAX image files to AVIF, our tool allows you to also adjust the image with some simple effects such as applying a greyscale filter to the image. These additional options are available within the Options tab. Along with Greyscale, you can also mirror/flip the image if needed. For single FAX file uploads you will also see options to resize and rotate your image.
Here are 2 simple steps to convert your FAX to AVIF.
First click the "Upload..." button, select your FAX file to upload. Select any configuration options. When the FAX to AVIF conversion has completed, you can download your AVIF file straight away.

The FAX file format introduced in the 1990's is a raster image file format intended to store digital versions of documents used by Fax (facsimile) machines that were popular at the time.
Although Fax machines have been slowly replaced since then by internet based communications such as Email and Instant Messaging the FAX file format is still used for certain applications and the files can be edited within some 3rd party applications.
The AVIF format is an image based container format designed to store image or image sequences which are compressed with the AV1 compression algorithm. The format has been around since 2019 and is based on the HEIF container format and as such it competes with the HEIC image format.
During tests the format has shown to perform better than JPG files not just in the reduced file size but in overall image quality. Support for the format is growing and is already supported in the Chrome and Firefox web browsers. AVIF files can also be opened in many 2D image editing applications.
