The PXB file format is associated with Pixibox, a software tool used for digital painting and drawing. PXB files contain image data, including layers, colors, and brush strokes, allowing users to save and reopen their work without losing any details or quality. This format is specifically designed to preserve the complexity of digital art, making it ideal for artists who wish to continue editing their creations. PXB files are proprietary to the Pixibox application and may require this specific software to view or edit the content.
Based on HEVC (High-Efficiency Video Coding), the HEIF format is an image file container with one or multiple images and is the default image format for Apple Live Photos. It replaced the JPEG format as it's smaller in size and has lossless compression ensuring high-quality photos.
