What happens to transparent areas when converting TIFF to BMP?

BMP has no alpha channel, so transparency cannot be carried over. FileMorf flattens transparent regions onto a clean white background rather than leaving them black, which is what naive converters often produce. If keeping transparency matters, convert to PNG or WebP instead.

More systems than you might expect: legacy Windows applications, embedded devices, receipt and label printers, scientific imaging tools, and some game-modding pipelines. FileMorf writes plain uncompressed 24-bit BMP — the most universally readable variant of the format.

How large will the BMP file be?

Large. FileMorf writes standard uncompressed 24-bit BMP, which needs about 3 bytes per pixel regardless of content — a 4000x3000 image comes out around 34 MB. That is normal for BMP; only use it where a specific application requires the format.

What happens to multi-page TIFF files?

Only the first page is converted, and FileMorf flags this with a warning on the file so nothing is silently dropped. Single-page TIFFs — the vast majority of scans and photo exports — convert in full, including LZW-compressed and uncompressed variants.

Questions about TIFF and BMP.

Check the format behavior, limitations, and follow-up options before processing a real file.

Some industrial tools, printer utilities, and decades-old Windows programs read BMP but choke on TIFF's many compression variants. Converting writes the decoded pixels as a plain uncompressed bitmap that anything on Windows can open — no codecs, no surprises. Transparency is flattened onto white, and the file stays large, since neither format applies meaningful compression here.
