Frequently asked questions
Converting JPG to AVIF is worth doing when you need what AVIF offers: the smallest files of the common formats. JPG gives you small files and universal support, but its drawback is no transparency, and each save loses a little detail.
How it works
- Add your JPG files.
- The output format is already set to AVIF.
- Adjust quality if the format supports it.
- Download the converted AVIF files.
Good to know
One thing to keep in mind: slower to encode and not supported everywhere yet. Converting does not repair damage already present in the source — if the JPG was heavily compressed, those artefacts carry across into the AVIF.
Frequently asked questions
Is converting JPG to AVIF lossless?
AVIF is a lossy format, so the conversion re-encodes and discards a little detail. At high quality settings the difference is not visible in normal viewing.
Why convert JPG to AVIF at all?
Usually for the smallest files of the common formats. If neither of those matters for your use, keeping the JPG is perfectly fine.
