What HEIC to BMP conversion does

Convert a HEIC photo to BMP directly in your browser. BMP is a widely recognized uncompressed bitmap format still expected by some older Windows software and compatibility workflows.

How to convert HEIC to BMP

1. Choose a HEIC file.
2. Select Convert & download.
3. Save the .bmp file from your browser downloads.

Why use this conversion

BMP is the format some legacy Windows applications, print pipelines, or embedded/older tooling expect by default.

Transparency and output quality

BMP output here is 24-bit RGB with no alpha channel. Transparent pixels from the source are flattened onto a white background, the same convention used for JPG output. This tool writes an uncompressed 24-bit BMP, so the file will usually be noticeably larger than the source.

Privacy and local processing

• Processing occurs locally in the browser.
• Files are not uploaded to Looty Tools for conversion.
• Converted files remain on your device.

Limits and known issues

• Input: HEIC/HEIF (.heic, .heif) only, up to 25.0 MB and 8,192 px per side.
• BMP output has no transparency support in this tool — pick an output format that keeps alpha (WebP, AVIF, TIFF, ICO, or QOI) instead if you need to preserve transparency.
• Multi-image HEIC containers — bursts or Live Photos — download as multiple BMP files, or a ZIP when there is more than one. Every decoded image is kept; none are silently discarded.
• Metadata is not preserved in the downloaded file.

HEIC to BMP FAQ

Why convert HEIC to BMP?

BMP is the format some legacy Windows applications, print pipelines, or embedded/older tooling expect by default.

Does BMP output keep transparency?

No. BMP output here is 24-bit RGB with no alpha channel. Transparent pixels are flattened onto a white background, the same convention used for JPG output.

Is BMP output compressed?

No. This tool writes an uncompressed 24-bit BMP (BITMAPINFOHEADER, BI_RGB), so the file will usually be larger than the source.

What happens with a multi-image HEIC file?

Every decoded image is kept — a single-image HEIC downloads as one file, and a multi-image HEIC (a burst or Live Photo) downloads as a ZIP containing every decoded image, never just the first one.

Are my files uploaded?

No. Conversion runs locally in your browser and does not upload your file to Looty Tools servers.

What is validated before conversion?

The file must actually be a HEIC/HEIF container — the tool checks the ISO-BMFF ftyp brand, not just the filename or extension, before decoding.
