JPG (JPEG) – The Most Common for Photos

JPG (Joint Photographic Experts Group) is one of the most widely used image formats, especially for photographs and images with complex color gradients. It uses lossy compression, which reduces file size by discarding some image data, often without noticeable quality loss. This makes it ideal for situations where file size is a concern, such as on websites or for email attachments.

Best for: Photographs, website images, social media posts.
File size: Small (due to lossy compression).
Transparency: Not supported.
Quality: Good, but with slight quality loss when compressed.

WEBP – A Modern Format for the Web

WEBP, developed by Google, offers both lossy and lossless compression. It provides superior compression efficiency, making it an excellent choice for web optimization. With WEBP, you can maintain high-quality images at a fraction of the file size compared to JPG and PNG. Additionally, it supports transparency, making it versatile for both photographs and graphics.

Best for: Web optimization, faster page load times, mobile-first websites.
File size: Small (up to 30% smaller than JPG).
Transparency: Supported (like PNG).
Quality: High, with efficient compression.

PNG – Ideal for Transparency and High Detail

PNG (Portable Network Graphics) is a lossless image format, which means that no data is lost when the image is compressed. This makes it perfect for images that need to maintain their detail and quality, such as logos, icons, and graphics with transparency. While PNG images tend to have larger file sizes than JPG and WEBP, the ability to store transparent backgrounds is its standout feature.

Best for: Logos, icons, graphics with transparency, illustrations.
File size: Larger (due to lossless compression).
Transparency: Fully supported.
Quality: Excellent for sharp, detailed images.
