Questions about converting images
Are my files uploaded?
No. Your browser processes the files on your device. Conversion does not send your images to a server.
Will converting JFIF to AVIF improve image quality?
Changing the format cannot restore detail already lost. Keep the original dimensions to avoid unnecessary resampling; lossy output formats can discard additional detail.
