Frequently asked questions
Does converting JPG to AVIF lose quality?
AVIF is a lossy format, so the encoder re-compresses the image. swapfile.io uses a high default quality; for photos the difference is not visible in normal use.
Is my file uploaded to a server?
No. This tool runs entirely in your browser. You can open your browser's network tab and verify no request carries your file.
What happens to the metadata?
Re-encoding through the browser produces a clean file: EXIF, GPS and C2PA metadata are not carried over to the output.
