Convert HEIC to Lossless BMP Format
Patent-encumbered (HEVC/H.265 licensing) and requires special codecs on Windows and older Android devices. Converting to BMP gives you a key advantage: zero processing overhead — raw pixel data can be read directly into memory without a decompression step. BMP is best for uncompressed pixel data for windows system graphics and legacy applications requiring raw bitmap access.
Why Convert HEIC to BMP?
Patent-encumbered (HEVC/H.265 licensing) and requires special codecs on Windows and older Android devices — converting to BMP overcomes this by providing zero processing overhead — raw pixel data can be read directly into memory without a decompression step
BMP is the right choice when you need to: intermediate format for image processing pipelines that need raw pixel access
Gain broader compatibility — BMP works with Windows (native), macOS, Linux, all image editors; rarely used on the web
Prevent further quality degradation — once converted to BMP, no additional data is lost on re-saves

How to Convert HEIC to BMP
Upload your HEIC file
Drag your .heic file onto the upload area or click to browse. We accept HEIC files up to 50 MB.
Choose BMP as output format
Select .bmp (Windows Bitmap) from the format list. BMP uses lossless encoding, so your output quality matches the source.
Convert and download
Click Convert and wait for processing. Your BMP file will be ready to download in seconds. The result is optimized for uncompressed pixel data for windows system graphics and legacy applications requiring raw bitmap access.
Frequently Asked Questions
Will converting HEIC to BMP improve my file's quality?
expand_more
No — converting a lossy HEIC to lossless BMP preserves exactly what you have, but cannot restore data already discarded by HEIC compression. The benefit is that no further quality is lost on subsequent edits and re-saves.
How large will my BMP file be compared to the original HEIC?
expand_more
HEIC files are typically 1 MB – 8 MB, while BMP files are typically 1 MB – 100 MB. The actual size depends on content complexity and any quality settings you choose.
What software can open the converted BMP file?
expand_more
BMP is compatible with: Windows (native), macOS, Linux, all image editors; rarely used on the web.
What is the maximum file size I can convert?
expand_more
PureConverter accepts HEIC files up to 50 MB. Your files are processed securely and deleted from our servers after conversion.
What's the difference between HEIC and BMP?
expand_more
HEIC (High Efficiency Image Container) is best for storing iphone and ipad photos at half the file size of jpeg with no visible quality loss. BMP (Windows Bitmap) is best for uncompressed pixel data for windows system graphics and legacy applications requiring raw bitmap access. Key tradeoff: HEIC's advantage is roughly 50% smaller than jpeg at the same quality, with support for 10-bit hdr, depth maps, and burst sequences, while BMP's advantage is zero processing overhead — raw pixel data can be read directly into memory without a decompression step.
Pro Tips for HEIC to BMP Conversion
BMP preserves full quality, so your output file will be as good as the HEIC source — no need to worry about compression artifacts
If your HEIC file has transparency, make sure BMP supports it — BMP supports transparency
BMP works especially well for: screen capture output from older windows tools and apis
Did you know? BMP files store pixel rows bottom-to-top by default (origin at bottom-left), a convention inherited from OS/2 that confused generations of graphics programmers.
