TIFF to BMP Converter

TIFF is a flexible format used in professional photography and print: it can hold 16-bit color, CMYK, transparency, multiple pages, compression and extensive metadata. BMP, or bitmap, is a much simpler format from Windows that stores pixels with no compression and very little else. The BMP files this tool writes are 24-bit RGB, with no transparency, profiles or EXIF data. That simplicity is why some older or specialized software accepts only BMP.

Usually because a particular program or device asks for BMP: older Windows software, some industrial and embedded systems, display or signage hardware, and certain specialist tools that only read plain bitmaps. If you work in TIFF, converting gives you a compatible copy without opening a full image editor. For everyday sharing or the web, JPG or PNG is a better choice, since BMP files are large and not widely supported online.

Pixel dimensions stay the same and BMP adds no compression, so an 8-bit RGB TIFF converts without loss. A few things do change. 16-bit TIFFs are reduced to 8 bits per channel, transparent areas are blended onto white because the BMP has no alpha channel, and CMYK images are converted to RGB. For a multi-page TIFF, only the first page is converted. For most photos the result looks identical on screen.

Choose BMP only when the software or device you are delivering to requires it. JPEG makes far smaller files for photos and is accepted almost everywhere, and PNG is lossless like BMP but compressed and able to keep transparency. BMP's advantage is that it is the simplest possible format to read, which is why some legacy programs, embedded systems and hardware tools insist on it. Otherwise, JPEG or PNG is the more practical choice.

Yes. Select or drop as many .tif or .tiff files as you like, and add more before converting. Click Convert to BMP and the files are processed one after another, each marked Done or Error, with a separate BMP downloaded for each. Your browser may ask once to allow multiple downloads. Files already converted are skipped if you click again, and Clear All empties the list.

It is not carried over. The BMP format has no standard place for EXIF data, so camera settings, capture dates, copyright notices, keywords and embedded color profiles in your TIFF are not included in the BMP. Keep the original TIFF as your master file so that information is preserved, and use the BMP only as a delivery copy for the software or device that needs it.

A 24-bit BMP stores three bytes per pixel, so it is about the same size as an uncompressed 8-bit RGB TIFF of the same dimensions. It will be smaller than a 16-bit TIFF or one with an alpha channel, because those extra bits are dropped, and larger than a TIFF saved with LZW or ZIP compression, because BMP stores every pixel without compression.

The most common cause is a color profile. If the TIFF was saved in a wide-gamut space such as Adobe RGB or ProPhoto RGB, the BMP has no profile to carry that information, so viewers treat it as sRGB and colors look muted. CMYK TIFFs are converted with a simple formula rather than a print profile, which can shift colors. Converting the TIFF to sRGB in your editor before using the tool gives the most predictable result.

There is no fixed limit, and nothing is uploaded: each TIFF is read and converted in your own browser. The practical limit is your device's memory, because the full image is decoded before it is written as a BMP. Large, high-resolution TIFFs work on a typical computer but take a little longer. On phones or older machines, convert very large files one or a few at a time.

BMP is an RGB-only format, so a CMYK TIFF has to be converted. The tool does this with a straightforward mathematical conversion and does not use the CMYK profile embedded in the file, so colors, especially rich blacks and saturated tones, may differ from what your editor shows. For accurate color, convert the TIFF from CMYK to RGB in a color-managed editor first, then convert that RGB TIFF to BMP.
