Complete Guide: HEIC to BMP Converter
Everything you need to know about using this tool effectively
The HEIC to BMP Converter transforms HEIC images into uncompressed BMP bitmap files. HEIC is Apple's high-efficiency format with excellent compression, while BMP stores raw pixel data with no compression. The tool decodes the HEIC, renders it to a canvas, and exports it as a BMP file. The tool processes everything in the browser, so your image never leaves your device.
This tool reads your HEIC file, renders it to a canvas, and exports it as BMP format. BMP does not support transparency, so any alpha channel in the HEIC will be flattened against a solid background. The output file will be much larger than the HEIC source since BMP is uncompressed.
Legacy software compatibility
Convert iPhone HEIC photos to BMP for use in older applications that cannot read HEIC files.
Image processing pipelines
Prepare HEIC images as BMP files for processing tools and libraries that require uncompressed bitmap input.
Embedded systems
Convert HEIC images to BMP for hardware and embedded systems that need raw pixel data.
Cross-platform sharing
Export iPhone photos as BMP files for Windows or Linux systems that lack native HEIC support.
Upload an image
Drag and drop or click to browse for your HEIC file.
Convert
Click Convert. The tool processes the image and generates a BMP file.
Download
Save the converted BMP image to your device.
BMP files are uncompressed and will be much larger than the HEIC source, often 10x or more.
HEIC supports transparency, but BMP does not, so alpha channels will be removed.
Use BMP when you need exact pixel data without any compression artifacts.
Consider converting to PNG instead for a smaller output with lossless quality.
Will the quality change?
No. BMP is uncompressed, so every pixel from the HEIC source is preserved exactly. There is no quality loss in the conversion.
Is my image uploaded to a server?
No. All processing happens in your browser using the Canvas API. The image never leaves your device.
What is the maximum file size?
The tool supports images up to 50MB. Since BMP is uncompressed, the output file may be very large.
Does BMP support transparency?
No. The standard BMP format does not support alpha channels. Transparent pixels in the HEIC will be flattened.
Can I convert multiple images at once?
Yes. Upload multiple files and the tool converts all of them.
