Can I customize the color and shape of a downloaded comic text bubble PNG?

While you can often change the color of a downloaded comic text bubble PNG using image editing software (e.g., via Hue/Saturation adjustments or color overlay layers), changing its shape is more difficult. PNGs are raster images, so direct shape manipulation without distortion is limited. For significant shape alterations, it's generally better to find a different bubble, use a vector graphic (SVG) that can be easily edited, or create your own bubble from scratch in a vector editor.
