BMP to TIFF Converter
Processing entirely on your device — large files may take a moment.
Bitmap Image and TIFF Image exist for different jobs: BMP is Windows’ native uncompressed bitmap format. Every pixel is stored exactly as captured, which makes files large but trivially simple to read — common in older software and scanners. Convert to TIFF when submitting scans or print-ready artwork where maximum fidelity is required.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.
