Select BMP fileTIFF has to be written on our server, so the file is uploaded, converted in memory and sent straight back. It is never written to disk and never stored. Need test files? Try our free sample files.
This free BMP to TIFF converter turns your .bmp images into .tif files. BMP turns up from legacy Windows software and scanners. It stores raw uncompressed pixels, so files are enormous for what they contain.
Because browsers cannot write TIFF, this one runs on our server: the file is converted in memory and sent straight back. It is never written to disk, never logged and never stored.

BMP and TIFF compared

| Extension | .bmp | .tif, .tiff |
| MIME type | image/bmp | image/tiff |
| Compression | Lossless | Lossless |
| Transparency | No | Yes |
BMP: Uncompressed raw pixels, which makes the files enormous and the format trivial to parse. Mostly encountered coming out of legacy Windows software and scanners.
TIFF: The lossless workhorse of print, scanning and archiving. Can hold multiple pages and very high bit depths, which makes the files large and keeps browsers from displaying them.
Frequently asked questions
How do I convert BMP to TIFF?
Drop your .bmp file onto the box on this page and the .tif file is ready to download in a second or two. There is no signup, no email, no watermark and no file limit beyond about 4 MB per upload — larger images are re-encoded smaller in your browser first, and the page says so when that happens.
Is this BMP to TIFF converter free?
Yes, completely, with no account, no trial and no watermark on the output. We are a consultancy and these tools exist because we needed them ourselves; there is nothing to buy on this page.
Are my files uploaded anywhere?
This one has to run on our server, because browsers cannot write TIFF. The file is converted in memory and returned immediately — it is never written to disk, never logged and never stored. If that is not acceptable for your file, use a desktop tool instead.
Will converting to TIFF reduce the quality?
Both formats can represent the same content here, so nothing meaningful is lost. Expect the file size to change, since BMP and TIFF compress differently.
Can I convert several BMP files at once?
Yes, up to 20 files in one go. Drop them all onto the box together and each one appears in the results list with its own download button.
