About HEIC and BMP
HEIC .heic
Apple's default photo format since iOS 11, storing HEVC-compressed images in a HEIF container. It is roughly half the size of an equivalent JPEG.
Good for
- About half the size of JPEG at similar quality
- Keeps transparency, depth maps and image sequences
- 10-bit colour, so smoother gradients than JPEG
Trade-offs
- Poor support outside Apple platforms — this is the usual reason to convert
- Patent-encumbered, which is why support is uneven
- Lossy, so quality does not come back
image/heic
BMP .bmp
Microsoft's plain bitmap. It generally stores pixels with no compression at all, which makes it simple to read and very large on disk.
Good for
- Dead simple — every pixel stored literally
- No compression artefacts of any kind
- Reliably readable by old Windows software
Trade-offs
- Enormous files, often ten times a PNG of the same image
- Effectively unusable on the web
- Transparency support is inconsistent between readers

HEIC and BMP side by side
| HEIC | BMP | |
|---|---|---|
| Compression | Lossy (HEVC) | Uncompressed |
| Transparency | Yes | Limited — 32-bit variants only |
| Animation | Yes — Live Photos and bursts | No |
| Typically used for | iPhone and iPad camera output | Legacy Windows software, intermediate working files |
What changes when you convert HEIC to BMP
Only the first frame survives
Most HEIC files are still images and convert straightforwardly. HEIC can also hold an animation, though, and BMP cannot: if yours is animated, what you get back is its first frame and nothing else. Convert to a video format, or to another animating image format, if the motion matters.
Why this conversion exists
HEIC is what an iPhone saves by default, and almost nothing outside Apple's ecosystem opens it — which is why most people arrive here. BMP trades HEIC's efficiency for the ability to open the file anywhere. Depth maps, Live Photo motion and any other auxiliary data in the HEIC are not carried across; what you get is the photograph itself.
Expect a very large file
BMP generally stores every pixel with no compression at all, so the result is often several times the size of the HEIC it came from while looking exactly the same. It is worth choosing only for old Windows software that will not read anything else.
Camera data is removed by default
A HEIC straight from a phone or camera carries EXIF metadata — model, settings, timestamp and, quite often, the GPS coordinates of where the photo was taken. The converted BMP is written without it, so a file you are about to share does not quietly carry your location. The orientation flag is read and applied to the pixels first, so the image will not come out sideways once the tag holding it is gone. If you need the metadata kept, there is a setting for it.
How the BMP is written
Our default is stored as plain uncompressed pixels, since that is essentially all BMP offers. The quality control on the converter moves this if you need to — the default aims to be indistinguishable from the source at a sensible file size, rather than to win a compression benchmark.
Quality cannot come back
HEIC already discarded detail permanently, and BMP stores exactly what it is given. The result will be considerably larger while sounding identical to the HEIC you started from — lossless preserves, it does not restore. That is still the right move if you are about to edit, because further saves will not degrade it again.

Why your PNG is so much bigger than your JPEG
The same photograph can be 300 KB as a JPEG and 4 MB as a PNG. Here is what each format is actually doing, and how to tell which one your file wants to be.

Where your transparent background went
Transparency is the property most often lost silently in a conversion — the file looks perfect until it lands on a coloured background and grows a white rectangle.
