Why would I need BMP instead of TIFF?

Some older Windows software, print workflows, or legacy tooling specifically expects an uncompressed BMP file.

Are my files uploaded?

No. Conversion runs locally in your browser and does not upload your file to Looty Tools servers.

What is validated before conversion?

The file must actually be a TIFF — the tool checks the byte-order header (little-endian ‘II*’ or big-endian ‘MM*’), not just the filename or extension, before decoding.

How to Convert TIFF to BMP in Your Browser

Converting a TIFF image to BMP produces an uncompressed 24-bit bitmap that older Windows software and some print or legacy pipelines expect. This guide covers the steps and what to know about transparency and file size.

Step-by-step conversion

Open /tools/tiff-to-bmp.
Choose a TIFF or TIF file — the content is validated before conversion, not just the filename or extension.
Select Convert & download.
Save the .bmp file from your browser downloads.

Transparency and file size

BMP output here is 24-bit RGB with no alpha channel, so transparent pixels are flattened onto a white background, the same convention used for JPG output. Because BMP is uncompressed, the resulting file is usually larger than the source.

Source-specific behavior

Multi-page TIFF: only the first page is converted. Additional pages are not extracted or included in the download.

Privacy

Conversion runs locally in your browser. The file is not uploaded to Looty Tools servers for this workflow.

Convert TIFF to BMP FAQ

Why would I need BMP instead of TIFF?: Some older Windows software, print workflows, or legacy tooling specifically expects an uncompressed BMP file.
Does this convert every page of a multi-page TIFF?: No. Only the first page (IFD) is converted. Additional pages are not extracted or included in the download.
Does BMP output keep transparency?: BMP output here is 24-bit RGB with no alpha channel, so transparent pixels are flattened onto a white background, the same convention used for JPG output. Because BMP is uncompressed, the resulting file is usually larger than the source.
Are my files uploaded?: No. Conversion runs locally in your browser and does not upload your file to Looty Tools servers.
What is validated before conversion?: The file must actually be a TIFF — the tool checks the byte-order header (little-endian ‘II*’ or big-endian ‘MM*’), not just the filename or extension, before decoding.
