How do I convert TIFF to BMP?

Add your TIFF file to the upload area above, then press Convert. The BMP file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to BMP reduce quality?

No. BMP is a lossless format, so the conversion preserves exactly what is in your TIFF file. Note that it cannot recover detail that was already discarded when the TIFF was first created — a lossless container does not undo earlier compression.

How large a file can I convert?

Up to 120 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

TIFF and BMP explained

TIFF is a flexible container used in print, publishing and archiving. It can hold multiple pages, layers, and a variety of compression schemes including none at all, which is why TIFF files vary enormously in size.

BMP stores pixels essentially raw, with little or no compression. A 1920×1080 BMP is around 6 MB regardless of what the picture contains, because every pixel takes the same space whether it is part of a gradient or a flat colour.

Where TIFF files come from: Scanners, professional photography workflows, and print production.
Where BMP is used: Legacy Windows software, some scientific and industrial imaging tools.

TIFF vs BMP

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

TIFF compared with BMP
Property	Source	Target
Compression	Lossy or lossless	Uncompressed
Transparency	Yes	No
Animation	No	No
Introduced	1986	1990
Browser support	Professional tools yes, web browsers no.	Broad, though rarely the best choice today.

TIFF is stronger at: Lossless, with optional compression. Supports multiple pages in one file. Handles CMYK and high bit depths for print.
BMP is stronger at: Trivially simple to read and write. No compression artefacts whatsoever. Still readable by very old software.

Why convert TIFF to BMP?

People make this switch when they run into the limits of TIFF: anything involving the web or casual sharing. BMP is the better fit when a legacy application specifically requires it.

Be aware of the size trade-off: BMP is uncompressed, so expect the converted file to be considerably larger than the TIFF you started with.

TIFF limitations that prompt the switch: No browser support at all. Large files. The format's flexibility means some TIFFs will not open in some readers.
What you give up: Enormous files. No standard support for transparency in most variants.

Does converting TIFF to BMP reduce quality?

Both formats store the content without discarding data, so this conversion preserves it exactly. The file size may change because the two formats compress differently, but the content itself is unaffected.
