What happens when you convert HEIC to BMP
- iPhone photos use wide-gamut Display P3 color; it's converted to standard sRGB so colors look right everywhere.
- Works in Safari, Chrome and Edge. Firefox can't open HEIC yet.
- BMP is lossless, so nothing more is lost in the conversion. Detail already removed by HEIC compression doesn't come back, and the file is usually larger.
- BMP has no transparency, so transparent areas are filled with a background color you choose (white by default).

Frequently asked questions
Is it safe to convert my files here?
Yes. Conversion happens entirely in your browser. Your files are never uploaded to a server, so nobody else can see them.
Is it free? Are there limits?
It's completely free, with no sign-up, watermarks or daily limits. The only limit is your device's memory for very large files.
Can I convert many HEIC files at once?
Yes. Drop as many files as you like; they're converted one after another and you can download them all as a ZIP.
Will converting HEIC to BMP reduce quality?
No. BMP is lossless, so the image is saved exactly as it is. Detail already lost in HEIC can't be restored.
Does BMP keep transparency?
BMP doesn't support transparency, so transparent areas are filled with a background color you can choose.
Why is my BMP file bigger than the HEIC?
HEIC uses stronger compression than BMP. The picture stays the same, but BMP needs more bytes to store it.
Which browsers does the HEIC to BMP converter work in?
It works in the latest Safari, Chrome and Edge, on computers and phones.
