TIFF to BMP Converter — Free, Online, No Upload

TIFF is the professional archival format, but not every application can read it. Older Windows software, legacy industrial tools, and some embedded systems that understand BMP natively but have no TIFF library will fail to open a TIFF file. Converting to BMP makes the image readable by any Windows application ever written.

BMP is Windows' built-in uncompressed image format, and it's been part of the OS since version 1.0. Paint opens it. Older VB6 and Delphi applications handle it natively. Some label printers, CNC controllers, and machine vision systems require BMP because their embedded image decoders only handle uncompressed Windows bitmap data. If TIFF is being rejected by a legacy tool, BMP is the reliable fallback.

Both BMP and TIFF can be lossless formats, so the conversion doesn't degrade image quality — every pixel is preserved. File sizes for BMP will be similar to or slightly larger than uncompressed TIFF, since BMP has no compression option in its basic form. If the source TIFF uses LZW or ZIP compression, the BMP will actually be larger than the TIFF. TIFF features like layers, multi-page support, and embedded ICC color profiles are not carried over to BMP — you get a flat, single-page, uncompressed image. For 16-bit TIFF sources, BMP will represent the image in 24-bit (8 bits per channel), so high bit depth is lost.

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

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