Convert PHM to HEIC

The PHM file extension stands for Portable Float-map Image (16-bit half), a format used for storing High Dynamic Range (HDR) images with 16-bit half-precision floating-point values. This format is particularly useful in applications requiring precise color representation and extensive dynamic range, such as computer graphics, image processing, and scientific visualization. Originating from the Portable FloatMap (PFM) format, PHM was developed to provide a more efficient storage solution by utilizing half-precision floats, thereby reducing file size while maintaining significant detail and accuracy.

The High Efficiency Image Container (HEIC) is a file extension used to store images and image sequences, leveraging the High Efficiency Image Format (HEIF). Developed by the Moving Picture Experts Group (MPEG) and introduced in 2015, HEIC files are acclaimed for their superior compression efficiency, which allows for high-quality images at smaller file sizes. This format is widely used in modern digital devices, including smartphones and cameras, to optimize storage capacity without compromising image quality. It supports advanced features such as live photos, burst photo sequences, and transparent images, making it integral for contemporary digital imaging solutions.
