What does converting HEIC to BMP mean?
HEIC is the default photo format used by iPhones since iOS 11, based on the HEIF container, while BMP is an uncompressed raster format that stores every pixel with no compression at all. Convert HEIC to BMP for use in Windows applications or legacy software that requires uncompressed images.
HEIC achieves excellent compression — roughly half the size of an equivalent JPG — but has limited compatibility outside Apple's ecosystem, which is why converting to a more universal format is often necessary.
BMP files are typically 10-20 times larger than an equivalent JPG or PNG because no compression algorithm is applied. It remains common in Windows-native applications and legacy software.

When to convert HEIC to BMP
Preparing HEIC files for legacy Windows applications that require raw, uncompressed pixel data
Convert HEIC images to BMP when your project specifically calls for legacy Windows applications that require raw, uncompressed pixel data.
Reducing file size
If BMP compresses better than HEIC for your content, converting can significantly cut storage and bandwidth needs.
Improving compatibility
Some platforms and software only accept certain formats — converting to BMP ensures your HEIC files open everywhere they need to.
Batch migrating a library
Convert a whole folder of HEIC images to BMP at once instead of opening each file individually in an editor.

Frequently Asked Questions
Will converting HEIC to BMP reduce image quality?
Since BMP is a lossless format, no additional quality is lost when converting your HEIC file. If the original HEIC was already compressed with quality loss, that loss can't be recovered, but nothing further is discarded.
Does BMP support transparency?
No, BMP does not support transparency. Any transparent areas in your HEIC file will be filled with a solid background (typically white) when converted to BMP.
Is it safe to convert HEIC files to BMP here?
Yes. The whole HEIC to BMP conversion runs locally in your browser using the Canvas API — your HEIC files are never uploaded to a server.
Can I convert several HEIC files to BMP at once?
Yes, drop multiple HEIC files at once and click Convert All — each one is converted to BMP and can be downloaded individually or as a ZIP.
Does converting from HEIC keep my photo's original quality?
The conversion decodes the HEIC file at full resolution before re-encoding it as BMP, so no extra quality is lost beyond what the BMP format itself introduces.
Is there a size limit for HEIC uploads?
There's no hard limit set by Pixvert for HEIC files, but very large files depend on your device's available memory to convert smoothly.
Can I use the BMP output commercially after converting?
Yes, converting HEIC to BMP only changes the file format — it doesn't alter your rights over the image or add a watermark.
