HEIC

HEIC is an image format based on HEVC compression, used by default for photos on iPhones and iPads. It stores photos at roughly half the size of a JPG of similar quality and supports depth data, Live Photos, and HDR. Windows and many web services do not open HEIC everywhere, so it is often converted to JPG or PNG.

BMP

BMP (Bitmap) is a raster image format developed by Microsoft for Windows. It usually stores pixels without compression, so images keep full detail but files are large. BMP is mostly used by legacy software and is often converted to PNG or JPG to save space.

What happens when HEIC becomes BMP

Source format

HEIC is a high-efficiency image container that may contain multiple images and metadata.

Target format

BMP is a simple bitmap format that is often uncompressed and therefore large.

What changes

The HEIC pixels are decoded and written using BMP compression and color capabilities.

What is preserved
Pixel dimensions and visible composition are preserved unless resize or crop settings are selected.
What may be lost
BMP cannot preserve transparency. Transparent pixels must be flattened against a background color.
Codec and quality implications
Color profile handling, bit depth, chroma sampling, and compression settings can change appearance or file size.
Realistic limitations
Multi-page, layered, animated, camera-raw, or very large images may be flattened, reduced to one frame, or rejected if the decoder cannot safely read them.

Conversion steps

  1. Upload a HEIC file no larger than 1 GB.
  2. Confirm that BMP is selected as the target.
  3. Download the BMP file and check the result before deleting your source.

Troubleshooting

The HEIC file is rejected or will not open.
Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
The BMP file is larger than expected.
Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
Transparency, color, or animation changed.
Choose a target that supports the needed feature and keep the original file; JPG cannot store transparency or animation.

Privacy and file retention

Uploads and converted files are processed automatically and irreversibly deleted within 24 hours. You can delete them sooner with the delete control. Convertr does not read, mine, sell, or manually review file contents.
