Technical note

What changes when you convert HFZ to PNG

Every cell in an HFZ file holds a measurement rather than a colour, usually elevation in metres, running from sea level up to whatever the highest point in the tile happens to be. PNG stores brightness, so the conversion stretches that range across a grey or colour scale. What you get is a readable picture of the terrain, and it is the right thing for a relief map or a figure. What you no longer have is the data: sampling a pixel in the PNG returns a shade, not an altitude. HFZ carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. PNG has nowhere to record any of that. The picture transfers intact, the location does not, so the output cannot be dropped onto a map afterwards without being placed by hand. Keep the HFZ original if the data still has to go back into a GIS.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as PNG opens on any computer and any phone. reaConverter produces those from HFZ in batch, entirely offline.

  • Render every file in a folder to PNG with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Stamp a text watermark, such as a project name or a date, on every image
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

I love that reaConverter can convert PDF pages to individual PNGs. I used it to extract images from a scanned document – each page became a high-res PNG with zero loss. It's like magic, but it actually works every time.

For my game development sprites, I need PNGs with perfect compression. reaConverter lets me fine-tune the color palette and compression level. It even preserves metadata. This is the only converter I trust for my asset pipeline.

I design stickers but could never cleanly resize my PNG logos without pixelation. reaConverter’s PNG-to-SVG tool keeps everything sharp—even when scaling up. My Etsy shop looks way more professional now!

FAQ

HFZ to PNG Conversion

What are HFZ files?

HFZ is the compressed version of the HF2 terrain height map format, in which the whole file is packed with the gzip method. A height map is a rectangular grid where every cell holds the elevation of one spot of a landscape, and such grids can grow very large when they cover wide areas in fine detail. HFZ keeps them small by combining two ideas: heights are stored as differences between neighboring cells, and the author chooses how precise the heights need to be. The same data can also be found with the .hf2.gz extension. In a published comparison, a terrain saved as HFZ took about 1.4 MB, while the same terrain in the TER format packed with gzip took 1.8 MB, at equal vertical precision.

What are PNG files?

The PNG (Portable Network Graphics) file format was designed in the mid-1990s as an improved alternative to the previously existing JPG and GIF formats, and as an extension which would be particularly web-friendly. In time, PNG files have gained a wide popularity and are highly appreciated at the moment for their ability to provide a lossless compression of images, which translates in high-quality and detailed renderings.
