For the web, AVIF is supported in most modern browsers and typically results in small file sizes. If you need maximum compatibility, JPG and PNG are safe defaults; for smaller files, WebP or AVIF are often better.
By default, QuickImager removes metadata (including EXIF) for privacy. If you disable “Remove metadata”, we will try to preserve compatible metadata when converting from BMP to AVIF, but some conversions may still drop it.
