How do I convert TIFF to BMP?

Upload your TIFF file above. It is converted to BMP automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.

Does converting TIFF to BMP lose quality?

No. Both formats are lossless, so every pixel is kept exactly.

Will the BMP keep the transparent background?

No. BMP can’t store transparency, so transparent areas are filled with the background colour you pick in Settings (white by default).

TIFF is the workhorse of print and archiving. It keeps every pixel without loss and is accepted by print shops, publishers and document-management systems.

Is the TIFF to BMP converter free?

Yes. Convert, preview and download a single result without creating an account. Premium adds batch conversion (many files into one ZIP) and larger uploads.

Why convert TIFF to BMP?

BMP is made for older Windows programs, embedded devices and tools that need raw pixels.
BMP needs no decoding, so very simple or older software can display it.

What to expect when converting TIFF to BMP

BMP can’t store transparency, so transparent areas are filled with the background colour you pick in Settings (white by default).
Expect a bigger file: BMP usually takes more space than TIFF for the same picture.
Only the first page of a multi-page TIFF is converted, and CMYK print colour becomes standard RGB.
