JPG vs. PNG: Which Image Format Should You Use?
When you're working with images on the web, two of the most common file types you'll encounter are JPG (or JPEG) and PNG. While they may look similar at a glance, they are fundamentally different and each has its own best use cases. Choosing the right one can impact your website's loading speed, image quality, and overall visual appeal.
What is a JPG?
JPG (Joint Photographic Experts Group) is a "lossy" compression format. This means that when an image is saved as a JPG, some of its data is permanently discarded to reduce the file size. This is why JPGs are fantastic for photographs and complex images with millions of colors. The compression is very efficient, allowing for small file sizes with minimal noticeable loss in quality to the human eye.
- Best for: Photographs, complex images with gradients, realistic images.
- Pros: Small file size, great for photos, widely supported.
- Cons: Lossy compression (quality degrades with each save), does not support transparency.
What is a PNG?
PNG (Portable Network Graphics) is a "lossless" compression format. Unlike JPG, a PNG file retains all of its original data when compressed, meaning there is no loss in quality. This makes it perfect for images that require sharp lines and high contrast, such as logos, icons, and text. Furthermore, PNGs have a killer feature: support for transparency. This allows you to have an image with a transparent background that can be placed over any color or pattern.
- Best for: Logos, icons, illustrations with sharp lines, images with text, images requiring a transparent background.
- Pros: Lossless quality (never degrades), supports transparency.
- Cons: Larger file size compared to JPG, not as ideal for photographs.
The Bottom Line: When to Use Which
The choice is simple when you know what to look for:
- If you have a **photograph**, use a **JPG**. The file size will be much smaller, and your website will load faster.
- If you have a **logo, an icon, or an image with sharp text and lines**, use a **PNG**. The quality will be crisp and perfect.
- If you need a **transparent background**, you must use a **PNG**.
