BMP to TIFF Converter
To convert BMP to TIFF, add your BMP files, choose TIFF and press Convert. Every pixel is copied exactly into a single-page RGB TIFF. Unlike BMP, the TIFF is compressed losslessly, so it is usually smaller while looking identical, and there is no quality setting. This suits scans and screenshots from older software. The conversion runs in your browser, so your files never leave your device.
- Free, no sign-up
- Your file never leaves your device
- Up to 200 MB per file
The selected format has no quality setting.
Your file never leaves your device; images are processed in your browser. EXIF and location data are not added to the output.
How to convert BMP to TIFF
Add your BMP files
Drag the images onto the upload area or browse for them; you can add several files at once.
Keep TIFF as the output
TIFF is already selected. For formats with a quality setting the slider starts at a default that suits the format (JPG 90%, WebP 80%, AVIF 60%); lower it if you want a smaller file.
Convert and download
Press “Convert”. Every file is processed in your browser, and you can download the results one by one or as a ZIP.
What is preserved?
Kept
- The image resolution (pixel dimensions)
- The correct photo orientation (EXIF orientation is applied)
- Colors (adapted to sRGB)
Not carried over
- EXIF, location and camera data: left out of the output for privacy
When to use it
Archive old scans and screenshots
Scanners and legacy Windows tools often saved BMP files. Converting them to TIFF keeps them lossless in a format archives commonly accept, at a smaller size.
Move bitmaps into publishing software
Layout and prepress programs work with TIFF more readily than BMP. The converted file can be placed into a document directly.
Limitations to know
- Up to 200 MB per file; the output can be at most 16,384 pixels on one side.
- On iPhone and iPad, images above roughly 16 megapixels may not be processed because of a browser limit.
About the formats
What is BMP?
BMP is a bitmap format that stores pixels with little or no compression, so files are large. It is simple and widely supported by Windows software but rarely used on the web; PNG gives the same pixel-exact result in a much smaller file.
What is TIFF?
TIFF is a high-quality image format used for scans, professional photography and printing. It typically stores pixels without lossy compression and can hold high color depth and several pages in one file, so files are very large. Web browsers do not display TIFF, so it is converted to JPG or PNG for sharing and publishing.
Frequently asked questions
Why is the TIFF smaller than my BMP?
A BMP usually stores every pixel uncompressed, while the TIFF uses lossless compression. Images with large plain areas shrink the most, without any change to the picture.
Is BMP to TIFF a lossless conversion?
Yes. Both formats keep pixels without loss, so the TIFF shows exactly the same colors as the bitmap.
Can I convert many BMP files at once?
Yes. Add all the bitmaps, choose TIFF once and download the results one by one or together as a ZIP.
Is converting BMP to TIFF free?
Yes, completely free. There is no account, subscription or watermark; just add your files and convert them.
Are my files uploaded anywhere?
No. Images are processed in your browser and never leave your device, so the waiting time depends on the file size and your device. EXIF and location data are not added to the output.
