Merging AVIF Images

Overview

The AVIF merge tool offers a simple and effective way to merge multiple AVIF image files into a single AVIF file. The tool runs within your browser and does not require any downloads or specialized software to run.

How to Use

Select the AVIF files from your device by either clicking the Upload Files button or by dragging and dropping the files onto the tool. The AVIF files can be arranged in the order you would like them to appear by dragging the individual files around within the tool preview window.

Once you have selected the AVIF files you wish to merge and have specified how the images should be arranged, whether that be vertically, horizontally, or in a grid layout, our tool can then get to work stitching the images together to form a single continuous AVIF file.

When your AVIF files have been submitted, they are loaded onto a virtual canvas and arranged in the manner specified, taking care to not lose any quality in the process.

When arranging your AVIF files, our tool will check the dimensions of the individual images and arrange them in a consistent manner. This means if you upload a mixture of portrait and landscape images, our tool is smart enough to deliver a consistent final image with all the images aligned correctly regardless of orientation.

All Done?

Once your images have been stitched together you will be presented with a preview along with a download link with which to download the final AVIF file.
