Answer 1

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
