In-Depth Explanation
Here's a breakdown of each format:
Portable Document Format (PDF)
- Purpose: Designed by Adobe Systems, PDF aims to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems. In essence, it ensures the document looks the same regardless of where it's viewed.
- Key Features:
- Portability: Can be viewed on any device with a PDF reader.
- Security: Supports password protection and encryption.
- Preservation: Preserves the original formatting of the document.
- Versatility: Can contain text, images, vector graphics, and even interactive elements.
- Usage: Widely used for distributing documents online, archiving, and creating fillable forms.
Joint Photographic Experts Group (JPG/JPEG)
- Purpose: JPG (or JPEG, both are used interchangeably) is a commonly used method of lossy compression for digital images. This means some image data is discarded during compression to reduce file size.
- Key Features:
- Lossy Compression: Reduces file size significantly, but can result in a loss of image quality. The level of compression can be adjusted to balance file size and image quality.
- Widely Supported: Supported by virtually all image viewers and editors.
- Suitable for Photographs: Particularly well-suited for compressing photographic images, where subtle variations in color and tone are common.
- Usage: The standard format for digital photographs, web images, and images shared online.
