Does BMP output keep transparency?

No. BMP output here is 24-bit RGB with no alpha channel. Transparent pixels from the source TIFF page are flattened onto a white background, the same convention used for JPG output.

Why isn't the TIFF-to-BMP size difference bigger?

This converter decodes TIFF into plain 8-bit RGB data rather than preserving whatever compression the source used, so the TIFF is often already close to uncompressed. Writing an uncompressed 24-bit BMP (BITMAPINFOHEADER, BI_RGB) on top of that usually produces a smaller size jump than converting from a genuinely compressed format like JPG.

Does this convert every page of a multi-page TIFF?

No — TIFF files are often multi-page scans, but this tool decodes and converts only the first page. Later pages are not included in the BMP download.

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.

What TIFF to BMP conversion does

Convert a TIFF image to BMP directly in your browser. TIFF's archival and print heritage already favors uncompressed, lossless data, so landing on BMP — another uncompressed bitmap — is a fairly natural translation, aside from losing any alpha channel and any pages beyond the first.

How to convert TIFF to BMP

Choose a TIFF or TIF file.
Select Convert & download.
Save the .bmp file from your browser downloads.

Why use this conversion

BMP is still what some legacy Windows applications, in-house print pipelines, or older embedded tooling expect by default — useful when a scanned or archival TIFF page needs to open in software that only recognizes .bmp.

Transparency and output quality

BMP output here is 24-bit RGB with no alpha channel. Transparent pixels from the source TIFF page (TIFF can carry alpha via its ExtraSamples tag) are flattened onto a white background, the same convention used for JPG output. This tool writes an uncompressed 24-bit BMP. Because this converter also decodes the TIFF into plain 8-bit-per-channel data rather than preserving whatever compression the source used, the size jump from TIFF to BMP is usually smaller and less dramatic than converting from a genuinely compressed format like JPG.

Privacy and local processing

Processing occurs locally in the browser.
Files are not uploaded to Looty Tools for conversion.
Converted files remain on your device.

Limits and known issues

Input: TIFF (.tif, .tiff) only, up to 25.0 MB and 8,192 px per side.
BMP output has no transparency support in this tool — pick an output format that keeps alpha (WebP, AVIF, TIFF, ICO, or QOI) instead if the source TIFF page has transparent pixels you need to keep.
TIFF files are frequently multi-page scanned documents. This tool reads only the first page — every page after it is left out of the BMP download entirely.
Metadata is not preserved in the downloaded file.

TIFF to BMP FAQ

Why convert TIFF to BMP?: TIFF is common in scanning, archival, and print workflows, but some legacy Windows applications, in-house print pipelines, or older embedded tooling only accept BMP. Converting produces an uncompressed bitmap those tools can open directly.
Does BMP output keep transparency?: No. BMP output here is 24-bit RGB with no alpha channel. Transparent pixels from the source TIFF page are flattened onto a white background, the same convention used for JPG output.
Why isn't the TIFF-to-BMP size difference bigger?: This converter decodes TIFF into plain 8-bit RGB data rather than preserving whatever compression the source used, so the TIFF is often already close to uncompressed.
