How do I convert BMP to TIFF?

Add your BMP file to the upload area above, then press Convert. The TIFF 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 TIFF reduce quality?

No. TIFF is a lossless format, so the conversion preserves exactly what is in your BMP file. Note that it cannot recover detail that was already discarded when the BMP 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.

BMP and TIFF explained

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.

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.

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

BMP vs TIFF

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

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

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

Why convert BMP to TIFF?

People make this switch when they run into the limits of BMP: almost always — PNG gives you the same lossless fidelity in a fraction of the space. TIFF is the better fit when printing, archiving, or handing files to a professional print workflow.

There is also a size argument: BMP stores data with little or no compression, so the TIFF version is normally dramatically smaller for the same content.

BMP limitations that prompt the switch: Enormous files. No standard support for transparency in most variants. Effectively unusable on the web.
What you give up: No browser support at all. Large files.

Does converting BMP to TIFF 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.
