BMP to TIFF Converter
Convert BMP images to TIFF entirely in your browser. BMP is uncompressed bitmap, large files, broad legacy support; TIFF is identical to TIF; the four-letter spelling preferred by some pipelines. The conversion runs locally using the Canvas API plus a small TIFF encoder — your file is decoded, re-encoded, and offered as a download without ever touching a server.
How to use
- Select one or more BMP files at once, or keep adding files to the queue.
- Click Convert all. Files are processed one at a time in your browser so memory stays bounded.
- A failed file does not stop the rest of the batch; use Retry failed after fixing or replacing it.
- Download each TIFF result individually, or download all successful results as a ZIP.
FAQ
Does the TIFF output have transparency?
Only if the source image had transparency. BMP files do not contain an alpha channel, so the resulting TIFF file will have an opaque background. To add transparency, edit the image first.
Is the BMP to TIFF converter free?
Yes. The full converter catalog is free. There is no upgrade tier, no quota, no watermark, and no signup.
Do my files upload to a server?
No. Conversion runs entirely in your browser. Open the Network tab in DevTools while you convert — you will not see your file leaving the page.
Why convert BMP to TIFF?
BMP is uncompressed bitmap, large files, broad legacy support. TIFF is identical to TIF; the four-letter spelling preferred by some pipelines. Converting between them is useful when the destination platform expects TIFF or when you want the trade-offs that TIFF offers.
What is the maximum file size?
Whatever your browser can hold in memory. On a modern desktop browser, several hundred megabytes is usually fine; on mobile, expect tighter limits.
