Format Details
BMP
BMP (Bitmap) is one of the oldest raster image formats, developed by Microsoft for the Windows operating system. It stores pixel data in an uncompressed or minimally compressed form, resulting in large file sizes but perfect lossless quality. BMP is widely supported across Windows applications and is commonly used as an intermediate format in image processing workflows.
imageTIFF
TIFF (Tagged Image File Format) is a flexible, high-quality raster image format widely used in professional photography, desktop publishing, scanning, and archival imaging. It supports lossless compression, multiple color spaces (RGB, CMYK, LAB), multi-page documents, and can embed multiple images within a single file. TIFF is the standard format for scanned documents, medical imaging, and any workflow that demands the highest possible image fidelity.
imageConverting BMP to TIFF: what actually changes
BMP to TIFF is one of the conversions this site performs, but the two formats are not interchangeable containers. Here is what the file keeps, what it loses, and how to get a result you can use.
What .BMP and .TIFF each hold
.BMP is a image format built for sharing, editing or publishing a picture, storing pixels, dimensions and colour depth. .TIFF is a image format built for sharing, editing or publishing a picture, storing pixels, dimensions and colour depth. Converting between them is a decision about which of those two jobs the result needs to do.
What changes in the conversion
Both files belong to the image category, so this is a like-for-like repackage: the same kind of content, stored in a different container. What changes is how .TIFF encodes pixels, dimensions and colour depth — not what the file is about.
Quality and file size
Both .BMP and .TIFF are lossless, so the content itself survives the trip intact. The main difference is how efficiently each format packages pixels, dimensions and colour depth — which is what changes the file size.
When this conversion is the right one
Reach for .TIFF when the software, device or platform you are sending to expects it — the content is the same image, only the packaging differs. The reverse direction works the same way, so you can always convert back from .TIFF to .BMP using the same tool.
Tips for a clean BMP to TIFF conversion
Start from the original file
Convert the .BMP you started with, not an earlier .TIFF output. Every extra round trip costs quality and can accumulate formatting drift.
Check the real type, not the extension
Image/bmp becomes image/tiff. If a file was renamed rather than converted, it will fail to open — rename it back to its true extension before uploading and the conversion will recognise it.
Watch transparency and animation
If the .BMP has a transparent background or animation, confirm .TIFF supports it. Where it does not, the background is flattened onto a solid colour and only the first frame survives.
Limits worth knowing
Uploads are capped per file (30 MB, or 100 MB for video) and processed temporarily — nothing is kept as a permanent copy. For huge image files, split or compress the source first.
Frequently Asked Questions
How do I convert BMP to TIFF?
Upload your BMP file on Convertek, select TIFF as the output format, then click Convert. Your TIFF file will be ready to download instantly.
Is the BMP to TIFF converter free?
Yes. Converting BMP to TIFF on Convertek is completely free with no watermarks. Fair upload limits apply (typically 30 MB per file).
Is my file kept after conversion?
No. Files are processed temporarily and not stored permanently. Converted downloads are available only in your browser session.
What is the difference between BMP and TIFF?
BMP and TIFF are different file formats with distinct use cases. Converting between them lets you use your file in software or workflows that require the TIFF format.
