Convert HEIC to BMP
HEIC is Apple's high efficiency photo format used by iPhones and iPads. Many apps cannot open it directly. BMP is the practical destination when HEIC is the thing standing in the way, because BMP is built for legacy Windows software and raw pixel data and almost every program opens it. Worth knowing before you start: BMP is lossless, so it preserves exactly the pixels that came out of the HEIC file. It cannot restore detail the HEIC encoder already discarded, and the file will usually get larger, not smaller. The conversion runs entirely in your browser: there is no upload, no file size limit and no watermark on the result.
Drop your HEIC files below and download BMP in seconds. Free, unlimited and completely private: the conversion runs inside your browser, so your files never leave your device and are never uploaded to a server.

Why convert HEIC to BMP?
Apple made HEIC the default camera format on iPhone because it stores photos at roughly half the size of JPG. Outside the Apple ecosystem support is poor: Windows needs paid extensions and many websites reject HEIC uploads, making it one of the most converted formats on the web.
BMP stores pixels with little or no compression, which makes files huge but trivially simple to read. It is mostly seen in legacy Windows workflows, screenshots from older tools and some scientific software. Converting to a compressed format usually shrinks a BMP by 90 percent or more.
HEIC vs BMP at a glance
| HEIC | BMP | |
|---|---|---|
| Full name | High Efficiency Image Container | Bitmap image |
| Compression | Lossy (HEVC) | Uncompressed |
| Transparency | No | No |
| Best for | iPhone and iPad photos | Legacy Windows software and raw pixel data |
What changes when you convert HEIC to BMP
| What happens | |
|---|---|
| Image quality | Unchanged from here on. BMP is lossless, so it preserves exactly the pixels decoded from the HEIC file. It cannot restore what the HEIC encoder already discarded. |
| Transparency | HEIC has no alpha channel, so there is no transparency to lose. |
| EXIF and GPS | Removed. The conversion goes through a pixel buffer, so camera data and location are not carried into the BMP file. |
| Colour profile | Not carried across. The image is handled in sRGB, which is right for the web and wrong for colour-managed print work. |
| Animation | Not applicable. HEIC files here are single images. |
| File size | Much larger. A 24 bit BMP costs three bytes per pixel regardless of content, so the file size is fixed by the dimensions alone. |

Frequently asked questions
What is a HEIC file?
HEIC is Apple's high efficiency photo format used by iPhones and iPads. Many apps cannot open it directly.
What is a BMP file?
BMP is an uncompressed Windows bitmap that keeps full pixel detail at a large file size.
Is it free to convert HEIC to BMP?
Yes. There are no limits, no watermarks and no account needed. Convert as many HEIC files as you like.
Are my files private?
Completely. Your HEIC files never leave your browser and are never uploaded to a server, so your images stay on your device.
