HEIF (High Efficiency Image Format) is an advanced image format developed by MPEG, utilizing HEVC (H.265) compression to store both still images and image sequences. Compared to traditional JPEG, HEIF offers superior compression efficiency, reducing file sizes by approximately 50% while maintaining the same image quality. It also supports 16-bit color depth, alpha channels for transparency, and depth maps, making it ideal for HDR and computational photography applications. Due to its efficiency and feature set, HEIF is widely used in iOS devices, macOS, and modern digital photography.

How to open and edit an HEIF file?

HEIF files can be opened and edited using various tools across different platforms. Recommended tools include: - Native Support: - iOS 11+: iPhones and iPads natively support HEIF files in the Photos app. - macOS High Sierra+: macOS users can open HEIF files directly in Preview or Photos. - Windows 10/11 (requires HEIF extension): Microsoft offers official HEIF and HEVC plugins (some may require purchase). - Professional Tools: - Adobe Photoshop 2020+: Supports HEIF file editing and conversion. - Affinity Photo: Allows HEIF import and editing, suitable for professional designers. - Open-Source Tools: - XnView MP: Multi-platform support for viewing and converting HEIF files. - GIMP (with plugin): Supports basic HEIF editing. - Online Conversion: - Websites like CloudConvert and Convertio allow users to convert HEIF to JPEG, PNG, and other common formats. On Windows, additional HEVC video extensions may be required to decode HEVC-compressed images properly.

TIFF (Tagged Image File Format) is a high-quality lossless image format widely used in publishing, printing, scanning, and professional graphic design. TIFF supports multiple color depths, layers, and compression methods (such as LZW, ZIP, and JPEG compression), making it ideal for image processing tasks requiring high precision and detail. Due to its lossless nature, TIFF files are typically large but retain image quality. Many professional software programs, such as Adobe Photoshop and GIMP, support TIFF editing, while IrfanView is useful for quick viewing.

How to open and edit a TIFF file?

TIFF files can be viewed, edited, and converted using various tools. Here are the recommended options:

1. Viewing TIFF Files:

   • Image Viewers: IrfanView, Windows Photos Viewer (default support in Windows 10 and later)
   • Browsers (partial support): Google Chrome (drag and drop the file into the browser window)

2. Editing TIFF Files:

   • Professional Image Editing Software: Adobe Photoshop, GIMP, CorelDRAW
   • Online Editors: Photopea (supports online TIFF editing)

3. Converting TIFF Files (to PNG, JPEG, PDF, etc.):

   • ImageMagick
   • XnConvert
   • Online Convert (online conversion tool)

Note: TIFF files may contain multiple pages (similar to PDFs). If you encounter a multi-page TIFF file, use Photoshop or IrfanView to view or split pages individually.
