BMP to TIFF Converter — Free, Online, No Upload

BMP and TIFF are both uncompressed or lightly compressed formats, but they serve different environments. BMP is the native Windows format, primarily used by Windows applications. TIFF is the professional standard used by print production, scientific imaging, document management systems, and archival workflows — and it's supported on Windows, macOS, and Linux alike.

If BMP files need to enter a print workflow, a TIFF is what InDesign, QuarkXPress, and professional print RIP software expect. Scientific labs that output image data to BMP (a common output from microscopy and industrial imaging equipment) often need to convert to TIFF before submitting images to journals or databases. Archival systems at libraries, museums, and government agencies mandate TIFF for long-term storage because of its standardization and metadata support.

Because BMP is uncompressed, the conversion to TIFF is lossless — every pixel is preserved exactly. TIFF with LZW or ZIP compression will often be smaller than the equivalent BMP, making the conversion a win both for compatibility and storage efficiency. TIFF also supports multi-page documents, 16-bit color depth, and embedded ICC color profiles — capabilities BMP lacks entirely. If you're archiving or publishing BMP images, TIFF is a strict upgrade.

Typical sizes (12MP photo): BMP 35–40 MB → TIFF 20–70 MB.

Both formats keep every pixel, so the TIFF looks the same as the BMP.
