Convert BMP to TIFF — Legacy to Professional
BMP is a legacy Windows format with no compression, resulting in massive files and limited professional tool support. TIFF is the industry standard for professional imaging, offering lossless LZW compression that can actually make your files smaller than the original BMP while maintaining perfect quality.

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.
Same format? You might want to compress instead.
SSIM-optimized — finds the lowest file size at your chosen visual fidelity.
Need to crop first? Use the Crop tool. Want to adjust or filter? Try the Editor.

Tip: Use PNG or WebP for transparent output. Standalone tool →
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 BMP to TIFF?
TIFF with LZW compression can be significantly smaller than BMP while remaining completely lossless. Professional imaging tools, print shops, and archival systems handle TIFF far better than BMP. This conversion upgrades your files from a legacy format to the professional standard with no quality loss and potentially smaller file sizes.
How to Convert BMP to TIFF
Upload your BMP file by dragging it into the converter or clicking to browse. Files up to 50 MB are supported.
KoalaPic reads the uncompressed pixel data and saves it as TIFF with LZW lossless compression.
Download the TIFF file. Both files are deleted after 1 hour.
Quality Note
Both BMP and TIFF are lossless, so this conversion has zero quality loss. The TIFF may actually be smaller than the BMP because LZW compression reduces the file size without discarding any pixel data.
