Save a JPG without a background
I have created this image in Photoshop:
I would like to save this arrow to a .jpg file without the white background rectangle. How can I achieve that? I was trying to hide the background layer before saving, but this doesn't help.
You can't save transparency to a .jpg. The file format simply doesn't support it. Anything that is transparent will become white when saved to a .jpeg.
Try .png or .gif, those file formats do accept transparency.
