Converting tif image white background to transparent png file format using image magick

I am trying to convert white color backgrounded tif image type to transparent background png image type using below image magick command in alfresco 5.1.

> magick convert source_file.tif -fuzz 20% -transparent white converted_file.png

But the above command is not working for all images. For many of images, the foreground color also changing to transparent partially .and for some images, the background is still showing white after conversion also.

please help me of finding a  generic imagemagick command which will change only background color without disturbing the image colour .

Note: I tried with multiple fuzz values like 1% to 20% but not at all helping me.

I think there are too much different possibilities to pack bitmaps in tiff images. Your conversion will only work, if it is possible to identify the "background" - for example in layered tiffs.

your conversion will try to use white als transparent Color, Even if it's not the background.
