Converting HEIC to BMP lets you take advantage of BMP's zero quality loss with pixel-exact storage of image data. HEIC files (High Efficiency Image Container) can be converted to BMP (Bitmap Image File) for better compatibility, smaller file sizes, or access to features that HEIC does not support.
HEIC (High Efficiency Image Container, introduced in 2015) uses HEVC (H.265) intra-frame compression. BMP (Bitmap Image File, introduced in 1986) uses None (RLE optional but rarely used) compression. HEIC supports transparency, but BMP does not. Transparent areas will be filled with a solid background color (typically white) during conversion. HEIC supports animation, but BMP does not. Only the first frame will be preserved during conversion. HEIC browser support: Limited (Safari only on macOS/iOS). BMP browser support: All modern browsers.
The quality impact depends on the specific settings used during conversion. BMP preserves full quality with lossless compression.
Typical HEIC file size: A 12MP iPhone photo: ~1.5-2.5 MB. Typical BMP file size: A 12MP photo: ~36 MB (24-bit uncompressed).
Before converting, choose your background color carefully. BMP does not support transparency, so transparent areas will be filled with a solid color. White is the default, but a specific brand color may work better for your use case.
