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). Since the source HEIC was already compressed with Apple's HEVC coding, the BMP file is typically noticeably larger than the original photo.

What happens with a multi-image HEIC file?

Each image inside a multi-image HEIC — a burst or Live Photo — becomes its own BMP file. A single-photo HEIC downloads one .bmp; a burst or Live Photo downloads a ZIP with one BMP per captured 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.

HEIC to BMP Converter

Convert HEIC and HEIF photos to BMP directly in your browser — a widely recognized uncompressed bitmap format for older Windows software and compatibility workflows.

What HEIC to BMP conversion does

Convert a HEIC photo — the format iPhones have saved camera shots in by default since iOS 11 — into a BMP bitmap directly in your browser. BMP trades away HEIC's efficient compression for something almost any Windows program, script, or print pipeline can open without a codec or plugin.

How to convert HEIC to BMP

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

Why use this conversion

A lot of non-Apple software, older Windows programs, and simple print or upload pipelines still can't read a HEIC file straight off an iPhone. BMP sidesteps that instantly — it's an old, simple, uncompressed bitmap that essentially every Windows imaging tool has always been able to open.

Transparency and output quality

BMP output here is 24-bit RGB with no alpha channel at all, so any transparent pixels are flattened onto a white background — the same convention this tool uses for JPG output. BMP stores raw, uncompressed pixel data, so converting a HEIC photo — already compressed efficiently with Apple's HEVC coding — into BMP typically produces a noticeably larger file, not a smaller one.

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 has no transparency support in this tool — if you need to keep alpha from a HEIC image, pick TIFF, ICO, or QOI instead.
A multi-image HEIC — a burst or Live Photo — produces one BMP per captured frame, delivered as a ZIP when there's more than one; nothing is silently discarded.
Metadata is not preserved in the downloaded file.
