免费在线 HEIC 转 PFM 转换器

HEIC is a file extension that Apple uses for the HEIF image format, which are usually coded by HEVC codec (High Efficiency Video Compression). This format is great for Live Photos because it can contain an image sequence. The best part about it is that you can store twice as many pictures in the HEIC format as in JPEG in the same size and quality because it uses the next-generation file compression.

This is a graphic file format that supports HDR. It is used for exchanging graphics data between applications. It is also used for development in the Netpbm suite of graphics editors. A PBM image has either a per-pixel RGB structure or instructions for representing grayscale tones.
