  5. PDF (Portable Document Format): PDF is a widely accepted document format that preserves the layout, fonts, and graphics of a document across different platforms. It is commonly used for sharing documents, such as reports, manuals, and forms, as it ensures that the content appears the same regardless of the software or operating system used.

  6. DOCX (Microsoft Word Document): DOCX is the default file format for Microsoft Word documents. It allows users to create, edit, and format text documents with various features, including images, tables, and charts. DOCX files are widely compatible with different word-processing software.

  7. XLSX (Microsoft Excel Workbook): XLSX is the file format used by Microsoft Excel for spreadsheets. It enables users to organize data, perform calculations, and create charts. XLSX files can store large amounts of data and support complex formulas and functions.

  8. ZIP (Compressed File Archive): ZIP is a common format used to compress multiple files and folders into a single archive file. This reduces the overall file size and makes it easier to share or transfer multiple files at once. ZIP files can be extracted using various compression software.

Image File Formats

When it comes to storing and sharing images, different file formats serve specific purposes. Here are some commonly used image file formats:

  1. JPEG/JPG: As mentioned earlier, JPEG is suitable for photographs and complex images with millions of colors. It achieves smaller file sizes through lossy compression, which removes some details that are less noticeable to the human eye. However, repeated saving of JPEG files may result in a loss of quality due to compression artifacts.

  2. PNG: PNG is ideal for images with transparency, as it supports alpha channels. It preserves image quality without sacrificing details, making it suitable for graphics with sharp edges, such as logos or illustrations. PNG files are typically larger than JPEG files but do not suffer from compression artifacts.

  3. GIF (Graphics Interchange Format): GIF is a file format commonly used for simple animations and graphics with limited colors, such as icons or animated memes. It supports transparency and can be saved in a lossless format, which preserves image quality, or a lossy format, which reduces file size at the expense of some quality.

  4. TIFF (Tagged Image File Format): TIFF is a flexible file format that supports lossless compression, making it ideal for storing high-quality images. It is commonly used by photographers and graphic designers who require uncompressed or minimally compressed files for editing or printing purposes. TIFF files are larger in size compared to JPEG or PNG files.
