Pro Tips

  • Converting JPG to PNG is highly recommended if you plan to edit the image further, as PNG prevents further quality loss.
  • While converting JPG to PNG won't magically add transparency to an opaque image, it creates a format where you can easily remove the background later.

What is the JPEG format?

JPEG (or JPG) is a commonly used method of lossy compression for digital images, particularly for photographs. Introduced in 1992, it quickly became the most widely used image compression standard in the world and remains the most common format for photos on the internet today. It achieves a remarkable 10:1 compression ratio with very little perceptible loss in image quality, although it does not support transparent backgrounds.

Understanding the PNG format

Portable Network Graphics (PNG) is a widely used raster-graphics file format that supports lossless data compression. It natively supports 24-bit RGB or 32-bit RGBA colors, meaning it can perfectly handle transparent backgrounds. While PNG files are generally larger than JPEGs because they retain 100% of their original visual quality, it remains the absolute best format for web graphics, logos, and high-quality digital art.
