Modern format with excellent compression. Limited browser support.

Apple's format. Excellent quality at small sizes.

Lossless format. Large files, ideal for print/archival.

256 colors max. Best for simple graphics.

Uncompressed bitmap. Very large files.

Vector trace. Best for logos and simple graphics. Not a pixel-perfect conversion.

Lossless format — files can be large

GIF is limited to 256 colors

Best for logos, icons, and line art. Photos produce stylized results.

BMP files are uncompressed and can be very large. Consider TIFF (LZW) or PNG for lossless with smaller file sizes.

Leave empty for all pages. Multi-page PDFs produce a ZIP.

Why Convert CR3 to BMP?

Only for legacy software requiring BMP. Use TIFF or JPG for most other purposes.

Quality Note

Uncompressed output. Very large files. TIFF with LZW is a better lossless choice.

Frequently Asked Questions

Only if a specific program demands it. BMP stores pixels uncompressed, offering no quality advantage over TIFF or PNG while producing much larger files. Some legacy Windows software and embedded display systems accept nothing else.

The BMP container is lossless, so nothing is lost after decoding. The RAW-to-8-bit step happens first and resolves the CR3’s 14-bit exposure latitude into fixed pixel values — that is where the flexibility goes, not in BMP itself.

About 74 MB for a 24 MP EOS R6 Mark II frame and roughly 137 MB for a 45 MP R5 frame. BMP applies no compression at all, so the size is width × height × 3 bytes plus a header.

No. BMP has no standard EXIF container, so camera body, lens, exposure settings and GPS coordinates are discarded entirely. Use TIFF or JPG when the technical record must travel with the image.
