Convert AVIF to JPG
Convert AVIF images to JPG directly in your browser. Your files are never uploaded.
What to know
AVIF supports transparency and JPG does not. Anything transparent has to be filled with a solid colour — this tool defaults to white and lets you change it. Converters that skip this step produce black backgrounds, which is the single most common complaint about JPG conversion.
AVIF uses AV1 video compression for still images and is the most efficient common format, with transparency and wide colour support. Encoding is slow, so browsers can read it far more readily than they can write it.
JPG throws away detail the eye is least likely to notice, which is why photos compress so well. It has no transparency channel at all, and every re-save loses a little more quality.
Questions
Are my AVIF files uploaded anywhere?
No. The conversion runs inside your browser using the Canvas API. The file is read into memory on your own machine and never sent over the network, which you can confirm by opening your browser's developer tools and watching the network tab stay empty.
Does converting AVIF to JPG reduce quality?
JPG is a lossy format, so some detail is discarded. Use the quality control to decide how much — around 80% is normally indistinguishable from the original, while lower settings trade visible artefacts for smaller files.
What happens to transparent areas?
JPG has no transparency channel, so transparent pixels are filled with a solid colour. This tool uses white by default and gives you a colour picker to change it. Many converters silently use black instead, which is why logos often come back looking wrong.
Is there a file size limit?
There is no limit imposed by the tool, because there is no server to upload to. The practical ceiling is your device's available memory — very large images may be slow on an older phone.
