This converter turns TIFF images into BMP files without uploading anything. The conversion runs inside this page using your own device's processor, so your photos never leave your computer — there is no server copy to worry about, no queue to wait in, and no limit on how many files you convert.
TIFF is the lossless archival format used by scanners, print shops and professional photographers. Standard in print and archival software; unsupported in every web browser. BMP, by contrast, strong on Windows, weak everywhere else, and never used online.
TIFF is what scanners and print workflows produce, and no browser will display it. Converting to BMP is usually the step between "I scanned this" and "I can actually send it to someone".
How to convert TIFF to BMP
- Add your TIFF files. Drag them onto the box above, click to browse, or paste an image straight from your clipboard. You can add as many at once as you like.
- Adjust the settings if you need to. The defaults suit most images. BMP is lossless, so there is no quality setting to adjust. Pick a background colour if your image has transparent areas.
- Download the BMP file. Each file gets its own download button as soon as it finishes, and you can pull the whole batch down as a single ZIP.
What changes when you convert TIFF to BMP
Every format conversion involves trade-offs, and vague tools hide them. Here is exactly what happens to your image in this particular conversion.
- BMP has no transparency channel, so any transparent areas are filled with a solid colour. White is used by default and you can pick a different colour before converting — this is the single most common surprise when going from TIFF to BMP.
- BMP stores every pixel uncompressed, so expect a very large file — often ten times the size of the TIFF you started with. That is normal and not a fault of the conversion.
What happens to the file size
Measured, not estimated: two 1200 x 800 pixels references — a photograph and a flat-colour graphic — put through this converter.
| Reference image | As TIFF | As BMP | Change |
|---|---|---|---|
| Photograph | 3.66 MB | 2.75 MB | -25% |
| Graphic with text | 3.66 MB | 2.75 MB | -25% |
Yours will differ: size depends more on what is in the picture than on the formats involved.
About TIFF (Tagged Image File Format)
TIFF is the lossless archival format used by scanners, print shops and professional photographers.
Where you probably got it: Scanners, fax systems, print workflows and professional photo software.
Strengths
- Lossless and high bit depth — the standard for archiving and printing
- Can hold multiple pages, layers and rich metadata
- The expected deliverable format for most commercial print work
Limitations
- No browser will display it, so it is useless on the web
- Very large files
- So many optional variants that readers disagree on what is valid
About BMP (Windows Bitmap)
BMP is Microsoft’s raw, uncompressed bitmap format — every pixel stored literally, with no compression at all.
Support: Strong on Windows, weak everywhere else, and never used online.
Strengths
- Dead simple and completely lossless
- Read by even the most primitive Windows tooling and embedded devices
- No decoding overhead, which some industrial and medical systems require
Limitations
- Enormous files — often 10–20x larger than a PNG of the same image
- Poorly supported on the web; browsers can display it but nobody serves it
- No transparency in the widely supported 24-bit form, so transparent areas are filled with a solid colour
Is it safe to convert TIFF online?
Here, yes — and you can check rather than trust. Open your browser’s developer tools, switch to the Network tab and convert a TIFF file: no request carrying your image is made. Disconnect from the internet after this page has loaded and the converter still works, which would be impossible if a server were doing the conversion.
That is worth verifying wherever you convert, because most online converters do upload, and TIFF files are so often scanned contracts, medical imaging and archival documents, since TIFF is what scanners and clinical equipment produce. Once a file is on somebody else’s server you are relying on a privacy policy rather than on anything you can observe. We wrote up how to tell a safe converter from a risky one in more detail.
Frequently asked questions
How do I convert TIFF to BMP?
Drag your TIFF file onto the box above, or click it to browse. The conversion starts immediately in your browser and the BMP download appears within a second or two for most images. You can drop in a whole folder of files at once and download them together as a ZIP.
Are my TIFF files uploaded to a server?
No. The conversion happens locally in your browser, so your files are never transmitted anywhere — the tool even works with the network disconnected once the page has loaded. That is also why there is no file size or file count limit: nothing costs us anything per conversion. The practical ceiling is your own device's memory, which on a phone means very large images may fail.
Does TIFF to BMP keep transparency?
It cannot — BMP has no transparency channel at all. Transparent pixels are filled with a background colour, which defaults to white. Use the background colour picker before converting if you need black or a brand colour instead. If you need to keep the transparency, convert to PNG or WebP rather than BMP.
Will converting TIFF to BMP reduce the quality?
No. Both TIFF and BMP are lossless, so every pixel is preserved exactly.
What is the difference between TIFF and BMP?
TIFF is the lossless archival format used by scanners, print shops and professional photographers. BMP is Microsoft’s raw, uncompressed bitmap format — every pixel stored literally, with no compression at all. In practice the choice comes down to compatibility: standard in print and archival software; unsupported in every web browser. Meanwhile strong on Windows, weak everywhere else, and never used online.
