Both BMP and TIFF preserve image quality without loss. The conversion between these formats is about gaining transparency support.
BMP (Bitmap Image File, introduced in 1986) uses None (RLE optional but rarely used) compression. TIFF (Tagged Image File Format, introduced in 1986) uses LZW, ZIP, JPEG, PackBits, CCITT, or None compression. TIFF adds transparency support that BMP lacks, which is valuable for logos, icons, and overlay graphics. BMP browser support: All modern browsers. TIFF browser support: None.
Both BMP and TIFF use lossless compression. The conversion preserves 100% of the original data — the output file is pixel-for-pixel (or sample-for-sample) identical to the input. No quality is lost during this conversion.
Typical BMP file size: A 12MP photo: ~36 MB (24-bit uncompressed). Typical TIFF file size: A 12MP photo (16-bit RGB): ~72 MB uncompressed; ~25-35 MB LZW. Expect a dramatic file size reduction — often 5-20x smaller — when converting from uncompressed BMP to TIFF.
For the best conversion results, always start from the highest quality source file available. Converting from a previously compressed file compounds any existing compression artifacts. When in doubt, use higher quality settings — you can always re-convert at lower quality later, but you cannot recover quality that has been lost.
