What is a BMP (Bitmap Image) file?

BMP, short for Bitmap Image File or Device-Independent Bitmap (DIB), is an uncompressed raster graphic format originally developed by Microsoft for Windows under the .bmp extension. It maps every pixel color value in raw byte arrays without compression.

Why convert BMP to HEIF?

Uncompressed BMP files consume excessive storage space, often taking up 30MB to 50MB per picture. Converting BMP to HEIF compresses the image using advanced video intra-frame coding, slashing file size by up to 95% while keeping visual quality virtually indistinguishable.

What is a HEIF (High Efficiency Image File Format) file?

HEIF, which stands for High Efficiency Image File Format, is a modern multimedia container specification established by the Moving Picture Experts Group (MPEG) under the ISO/IEC 23008-12 standard. Carrying the .heif or .hif file extensions, it encapsulates individual images, image burst sequences, and metadata using advanced video compression codecs like HEVC. It provides high-depth color gradations, transparency, and HDR tonal ranges at roughly half the file size of legacy JPEG files.

How to open and view a HEIF file?

HEIF files can be opened natively on macOS, iOS, Android 9 and newer, and modern Windows operating systems equipped with HEIF codecs. Photo applications such as Adobe Photoshop, Lightroom, GIMP, and darktable also offer comprehensive HEIF reading capabilities.

If you need to convert your pictures into lightweight HEIF files to save storage space while maintaining pristine visual quality, our private client-side converter processes your images instantly inside your web browser without uploading files to remote servers.
