What is an HEIC file?

HEIC (High Efficiency Image Container) is a file format based on HEIF (High Efficiency Image Format) using HEVC (H.265) compression. It allows storing high-quality images while reducing file size by approximately 50% compared to JPEG. HEIC supports 16-bit color depth, transparency, HDR, and multiple image storage (such as Live Photos). Apple devices (iOS 11+ and macOS High Sierra+) use HEIC as the default format, making it popular in mobile photography, digital imaging, and cloud storage.

How to open and edit an HEIC file?

HEIC files can be opened and edited using various tools. Recommended software and methods include: - **Native Support**: - [iOS Photos](https://support.apple.com/en-us/HT207022): View and edit HEIC files directly on iPhones and iPads. - [macOS Preview](https://support.apple.com/en-us/HT208967): Open HEIC files natively in Preview and Photos on macOS. - Windows 10/11 (requires HEIF extension): Microsoft provides official HEIF and HEVC plugins (some may require a purchase). - **Professional Editing Tools**: - [Adobe Photoshop 2020+](https://helpx.adobe.com/photoshop/using/file-formats.html#HEIF_HEIC): Supports HEIC editing and conversion. - [Affinity Photo](https://affinity.serif.com/): Allows HEIC import and editing, suitable for professional designers. - **Open-Source & Free Tools**: - [XnView MP](https://www.xnview.com/): Multi-platform support for viewing and converting HEIC files. - [GIMP](https://www.gimp.org/) (with plugin): Supports basic HEIC editing. - **Online Conversion**: - Use [CloudConvert](https://www.cloudconvert.com/) or [Convertio](https://convertio.co/) to convert HEIC to JPEG, PNG, or other common formats. On Windows, additional HEVC video extensions may be required to decode HEVC-compressed images properly.

What is a DJV file?

DJV (Digital Video) is a file format used to store image sequences, widely adopted in animation, visual effects, and digital media production. Compared to traditional single-frame image formats, DJV files support efficient storage and processing of multi-frame image sequences, particularly suitable for applications requiring high frame rates and high-quality images. DJV files are commonly used in post-production for film and television, offering fast read speeds and efficient compression ratios. They also support various color depths and embedded metadata, ensuring image quality and integrity. Recommended tools for viewing and editing include [DJV Imaging](https://www.djv.sourceforge.net/), which provides powerful image processing features and full support for DJV files. Developed by the open-source community, DJV aims to provide an efficient and flexible way to store image sequences, ideal for animators and visual effects artists who need quick access and high-fidelity image quality.

How to open and edit a DJV file?

To view and edit DJV files, you can use the following tools: - Viewers and Editors: [DJV Imaging](https://www.djv.sourceforge.net/), the officially recommended tool, providing full DJV file functionality and the best editing experience. - Free Alternatives: [FFmpeg](https://ffmpeg.org/), an open-source multimedia processing tool that supports converting and handling DJV files, suitable for technical users. - Conversion Tools: [ImageMagick](https://imagemagick.org/) (cross-platform), which can convert DJV files to other common image or document formats such as PDF or JPEG for use in various applications. Regardless of the tool you choose, the process is straightforward: simply double-click the file or right-click and select 'Open'. If you need to convert a DJV file to another format, many tools provide powerful conversion features, such as using ImageMagick for format conversion. Note that some advanced features (such as complex color adjustments) may not be fully supported in non-official tools. For DJV files containing sensitive information, ensure you use encryption features to protect the file. Steps are as follows: 1. Use a tool that supports encryption (such as a dedicated image editor). 2. Open the file and select 'File' > 'Save As' > 'Save as PDF or JPEG'. 3. In the export settings, choose 'Security', set a password, and select encryption options.
