HEIC to BMP

Why convert HEIC to BMP?

HEIC is a lossy format, while BMP is an uncompressed format. HEIC can have a transparent background, BMP can't.

  • No further quality loss

    BMP is lossless, so from here on the file keeps every detail - good for editing and archiving.

  • Where BMP works best

    Legacy Windows software (files are very large).

What is a HEIC file?

High Efficiency Image Container

Developed By
MPEG (Moving Picture Experts Group)
Initial Release
2015
MIME Type
image/heic

HEIC (High Efficiency Image Container) is the file extension used for images stored in the High Efficiency Image File Format (HEIF) specifically when encoded with the High Efficiency Video Coding (HEVC/H.265) standard. Adopted by Apple in iOS 11 and macOS High Sierra, it encapsulates single images or image sequences using the ISO Base Media File Format (ISOBMFF). It offers superior compression ratios-typically 50% smaller than equivalent JPEGs-while supporting 16-bit color depth, transparency (alpha channels), and non-destructive editing instructions.

How to open a HEIC file

Native support is available on macOS (High Sierra and later), iOS 11+, and Windows 10/11 (provided the HEIF Image Extensions and HEVC Video Extensions are installed from the Microsoft Store). Android 9 (Pie) and later also support the format natively. For older systems or non-compatible software, users often require conversion tools like iMazing HEIC Converter or must use viewers like VLC Media Player and GIMP, which have integrated HEIC decoding libraries.

What is a BMP file?

Bitmap Image File

Developed By
Microsoft
Initial Release
1985
MIME Type
image/bmp

The BMP (Bitmap) format, formally known as the Device Independent Bitmap (DIB) file format, is a raster graphics standard developed by Microsoft for the Windows operating system. The file structure consists of a file header (BITMAPFILEHEADER), an information header (typically BITMAPINFOHEADER), a color table, and the pixel array. Data is stored as a grid of pixels with color depths ranging from 1-bit to 32-bit, typically uncompressed, though the format supports lossless Run-Length Encoding (RLE4 or RLE8) and Huffman 1D compression for specific bit depths.

How to open a BMP file

Due to its simplicity and documentation as a core Windows standard, BMP files possess near-universal compatibility. They can be opened natively by virtually all image viewers and web browsers across Windows, macOS, and Linux without additional software. Standard utilities include Microsoft Paint, Apple Preview, and Windows Photos. For advanced manipulation, pixel-based editors like Adobe Photoshop and CorelDRAW are recommended, though the format is rarely used for complex editing due to its large file size.
