Choosing the right file format can significantly impact your project's quality and performance. Here's a breakdown of the three most popular formats.

JPG (Joint Photographic Experts Group)

JPG is best for photos. It uses lossy compression, which means it discards some data to make files smaller. This makes it perfect for social media and general web use where speed is more important than pixel-perfection.

PNG (Portable Network Graphics)

PNG uses lossless compression, meaning no quality is lost. It also supports transparency, making it the go-to choice for logos, icons, and website graphics with complex shapes.

PDF (Portable Document Format)

PDF is the king of documents. It preserves formatting across all devices and is ideal for sharing professional documents like invoices, contracts, and reports. It can contain both JPG and PNG images while maintaining document structure.
