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 PNG, but some conversions may still drop it.
QuickImager can work offline after the page (and any required format libraries) have loaded once. All conversion happens locally in your browser with no uploads.
