The AVIF file format is a new and efficient image compression format that can provide better image quality and smaller file sizes. AVIF is derived from the AV1 video coding standard and uses advanced compression techniques, including variable frame rate, variable resolution, and variable quantization. AVIF files can contain images with up to 16-bit depth, support transparency and animation, and can be created and edited in many different applications, including Adobe Photoshop, GIMP, and Microsoft Paint. The advantages of the AVIF file format are that it can provide better image quality and smaller file sizes, and it is widely used on the web.

PDF (Portable Document Format) is a versatile file format developed by Adobe that preserves the fonts, images, graphics, and layout of a document, regardless of the software, hardware, or operating system used to view it. It is widely used for sharing documents in a fixed layout, ensuring consistency across platforms. PDF files can be viewed on virtually any device, making it a preferred choice for documents that require secure and accurate presentation, such as eBooks, forms, manuals, and reports. PDFs also support interactive elements like hyperlinks, buttons, and forms, and can be encrypted for security.
