About the HTM format
HTM — HyperText Markup Language (short extension)
HTM is an alternate file extension for HTML, used historically by older Windows systems (FAT/NTFS 8.3 filename limitation) and some web servers. The file format is identical to HTML in every way — it contains the same markup language used to build web pages.
Common uses
- Legacy web page files from early Windows servers
- Old website archive recovery
- Windows 3.x and early IIS HTML files
- Converting older HTM files to modern HTML5
About the PGX format
PGX — JPEG 2000 VM Format
PGX is a simple raster image format used as a reference format in the JPEG 2000 verification model (VM). It stores single-component (grayscale) or multi-component images and is used in JPEG 2000 codec testing and validation environments.
Common uses
- JPEG 2000 codec testing and validation
- Reference image storage for compression research
- Multi-component image interchange in codec development
- Converting PGX test images to viewable formats
