Drop BMP files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. Open Options first if you want to change the defaults. The work happens in this tab.
Save the TIFF, or download everything as one ZIP if you converted several files.
The BMP to TIFF converter is part of this page and runs inside your browser. Your images are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
BMP files are uncompressed, so they are many times larger than they need to be. TIFF keeps full quality and is what print shops and archives ask for. BMP is at home in legacy Windows software and embedded devices; TIFF is the usual choice for scans, print production and archiving.
The defaults suit most files. Under Options you can resize the result.
BMP is the plain Windows bitmap: pixels written out with little or no compression. The files are enormous compared with PNG or JPG, but the format is so simple that old software, printers and microcontroller displays still ask for it.
Opens in Windows, macOS and most image apps; too large for the web
BMP converterTIFF is the workhorse of scanning, publishing and archiving. It keeps full quality, can hold several pages and carries rich metadata, but files are large and browsers other than Safari will not display it.

No. The BMP to TIFF conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
No further quality is lost: TIFF stores the decoded pixels exactly. The result is identical in content.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the BMP file, press Convert and save the TIFF. There is nothing to install.
Pictures of up to 120 megapixels are accepted (for example 12,000 by 10,000 pixels); a larger one is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
