I have an image in .jpg format with white background color. I want to remove the white background color to transparent in Imagemagick. I tried many ways but still the white background can not be removed. Can some one help me to solve this.

You cannot have transparent background colors in your JPEGs. The JPEG file format doesn't support transparency.

If you need transparent background, you need to convert the JPEG to

  • either PNG (high quality, filesize possibly larger than JPEG)
  • or GIF (in case you can tolerate low quality and a range of maximally 255 colors).

Example command:

convert  your.jpg  -transparent white  your.png
