Transparent background in JPEG image
Solution 1:
You can't make a JPEG image transparent. You should use a format that allows transparency, like GIF or PNG.
Paint will open these files, but AFAIK it'll erase transparency if you edit the file. Use some other application like Paint.NET (it's free).
Edit: since other people have mentioned it: you can convert JPEG images into PNG, in any editor that's capable of working with both types.
Solution 2:
If you’re concerned about the file size of a PNG, you can use an SVG mask to create a transparent JPEG. Here is an example I put together.
Solution 3:
JPEG can't support transparency because it uses RGB color space. If you want transparency use a format that supports alpha values. Example PNG is an image format that uses RGBA color space where (r = red, g = green, b = blue, a = alpha value). Alpha value is used as an opacity measure, 0% is fully transparent and 100% is completely opaque. pixel.
Solution 4:
JPG does not support a transparent background, you can easily convert it to a PNG which does support a transparent background by opening it in near any photo editor and save it as a.PNG
