BMP to TIFF Conversion FAQ
Does the BMP to TIFF converter keep transparency?
+
When TIFF supports an alpha channel (PNG, WebP, GIF) and the original BMP had transparency, we keep it. Converting to a format without transparency (JPG, BMP) fills transparent areas with white by default.
Can I batch-convert BMP images to TIFF?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Will the converted TIFF have the same dimensions as my BMP?
+
Yes — pixel dimensions are preserved by default. If you want to resize during conversion, use the TIFF resize tool after the conversion finishes.
Is my BMP image private when I convert it?
+
Yes. Uploads travel over HTTPS, nobody reads the contents, and nothing is shared. Your uploaded BMP and the resulting TIFF are deleted from our servers automatically about 24 hours after the conversion, which leaves time to download the result.
Why is my converted TIFF file larger than the original BMP?
+
If TIFF is lossless and BMP was lossy (or vice versa), file size will change. PNG (lossless) is typically larger than JPG (lossy) for photographs but smaller for solid-color graphics and screenshots.
Can I convert BMP to TIFF on my phone?
+
Yes. The converter is mobile-responsive and processes images server-side, so you can convert BMP to TIFF from any iPhone or Android device without using local storage.
