BMP stores raw pixel data with zero compression, resulting in very large files. Converting to HEIC applies lossless compression to make the file dramatically smaller without any quality loss.
BMP (Bitmap Image File, introduced in 1986) uses None (RLE optional but rarely used) compression. HEIC (High Efficiency Image Container, introduced in 2015) uses HEVC (H.265) intra-frame compression. HEIC adds transparency support that BMP lacks, which is valuable for logos, icons, and overlay graphics. HEIC supports animation, unlike BMP. However, converting a static image will not create animation. BMP browser support: All modern browsers. HEIC browser support: Limited (Safari only on macOS/iOS).
The quality impact depends on the specific settings used during conversion. HEIC uses compression that may affect quality depending on the chosen settings.
Typical BMP file size: A 12MP photo: ~36 MB (24-bit uncompressed). Typical HEIC file size: A 12MP iPhone photo: ~1.5-2.5 MB. Expect a dramatic file size reduction — often 5-20x smaller — when converting from uncompressed BMP to HEIC.
For the best conversion results, always start from the highest quality source file available. Converting from a previously compressed file compounds any existing compression artifacts. When in doubt, use higher quality settings — you can always re-convert at lower quality later, but you cannot recover quality that has been lost.
