What is a JPG file?
JPG (or JPEG) stands for Joint Photographic Experts Group, the team that created the standard back in the early 1990s. It’s one of the most common image formats in the world, known for compressing digital photos while retaining acceptable quality.
JPG uses lossy compression, which means some image data is discarded during saving. This makes JPG files smaller, ideal for web use, email, and social sharing - but less ideal for images that require fine detail or multiple edits.
How to open JPG files
JPG files can be opened on virtually any device - Windows, macOS, Android, iOS, Linux - using default apps like Photos, Preview, or third-party software such as Photoshop and GIMP. Even web browsers can display JPGs natively.
This universal support makes JPG the go-to format for photography, online graphics, and digital documents.

What is a ICO file?
ICO is a file format used for icons in Microsoft Windows. It stores one or more small images in different sizes and color depths, allowing Windows to scale icons across different UI components.
ICO files are essential for desktop software and websites (as favicons), and they can include both bitmap and PNG-based images.
How to open ICO files
ICO files can be opened with Windows built-in image viewer, Paint, or advanced tools like IcoFX, GIMP, and Photoshop (with plugins). macOS may require conversion first.
