Convert from tiff to png not working fine

[rokadeaks]

I have real image like https://ufile.io/mihvx which is in tiff format.
When I use convert command to convert from tiff to png I got image as follow
https://ufile.io/l4eez

Can you please help me to know why this is happening or reason behind it

The links don't work for me. The first seems to be to a web page that shows a png image, not tiff.

Please also show the exact command you used, and say what version of IM you used, on what platform.

EDIT to add: don't multi-post. I have deleted your other posts.

First image is png because I have took screen shot of real image to show you how it should be.
Second is converted image with convert command.

Command:

even I tried with simple convert command on command prompt like:

convert "D:/Mit Alphakanal und FSP nicht aktiviert.tif" "D:/Test_master.png"

The file I get downloaded is still PNG in both cases. The input is not TIFF! Please try again.

@fmw42:
Updated links can you please have look

[fmw42]

try

Code: Select all

convert mit-alphakanal-und-fsp-nicht-aktiviert.tif -alpha off mit-alphakanal-und-fsp-nicht-aktiviert.png

@fmw42 : It's working thanks but
Can you please explain me what's the reason basically & why we need to do -alpha off

[fmw42]

Simply because your file showed no actual full transparency. So I simply tried turning alpha off and it worked.

[fmw42]

You also have a clip path. If you want to use that to keep the background transparent, then try

Code: Select all

convert mit-alphakanal-und-fsp-nicht-aktiviert.tif -alpha transparent -clip -alpha opaque -strip result.png

Hi
I have existing command like this
convert.exe -limit memory 256MiB -limit map 1024MiB -limit disk 1024MiB -define bmp:format=bmp3 -antialias -quality 85 "D:/Mit Alphakanal Transparenz und FSP aktiviert.tif[0]" "(" +clone -threshold 100% -clip-path "frei" -alpha extract +clip -alpha copy ")" -compose copy_opacity -composite -profile D:/data/cache/icc/65f0b21506bf7bf8884ca1b0b9404565-0.icc -intent Relative -black-point-compensation -profile sRGB.icc -colorspace srgb -resize "1280x1280>" "D:/data/thumbs/master.png"


How we can add changes suggested by you in this command can you please guide

[fmw42]

I have no idea what you are trying to do. Can you explain? You command does not make sense to me. Why do you use -define bmp:format=bmp3 when you are creating a PNG output?

Here on link we have zip file in which 4 tiff files are there for all those 4 files I wish to convert to png.
Can you please provide me generic command with which for all 4 files I should have same png image after conversion.
