FAQ
HDF to QOI Conversion
What are HDF files?
HDF is the most common extension of files in the Hierarchical Data Format, Release 4, a container for scientific data developed at the National Center for Supercomputing Applications and now supported by The HDF Group. It is best known from satellite remote sensing: NASA's Earth Observing System adopted it in 1993, and instruments aboard the Terra and Aqua satellites, such as MODIS and ASTER, delivered their products in this form. One file may hold many layers, for example several spectral channels, a quality mask, and the coordinates of every pixel, along with notes that explain them. The same extension is used for the HDF-EOS variant, which adds conventions for geographic location. The newer HDF5 is a different format and is normally saved with other extensions.
What are QOI files?
QOIQOI (Quite OK Image) is a fast, lossless image format designed as a simpler alternative to PNG. It offers similar compression quality but with much faster encoding/decoding speeds, making it ideal for applications where performance matters.
