Technical note

HFZ to WEBP: what carries over and what does not

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. WEBP 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 WEBP returns a shade, not an altitude. Missing cells in an elevation grid, such as water, radar shadow or the edge of a survey, are not empty: they hold a sentinel value, -32768 in SRTM, -32767 in DTED and very often -9999 in ESRI grids. Counted as a real height, that value stretches the scale so far that the actual terrain collapses into a few near-identical shades. When a WEBP output looks flat and washed out, a void treated as data is the usual cause.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to WEBP 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.

As a graphic designer, I often receive WebP files from clients who don't know any better. reaConverter converts them to PSD or PNG with layers intact (when possible). It's the only tool that gives me back editable files. Absolute game‑changer.

I had a huge archive of WebP images from a client that I needed to convert to TIFF for printing. reaConverter handled it flawlessly – 500+ files in one go. No crashes, no quality loss. I'm genuinely impressed by the stability.

Google's WebP format is great for web performance, but not all platforms support it. reaConverter lets me convert WebP to JPEG and PNG in bulk, so I can use images everywhere. The batch processing is lightning‑fast, and the quality is identical to the original. A must‑have for any webmaster.

I use reaConverter's Watch Folder feature to automatically convert any WebP image dropped into a specific folder to JPG. This automates my entire image processing pipeline. Set it and forget it – that's how professional tools should work.

I downloaded thousands of WebP memes and wanted to share them with friends who use older phones. reaConverter turned them all to JPEG in minutes. Now everyone can enjoy the funny cat pics. Thanks, reaConverter, for being the hero of our group chat!

FAQ

HFZ to WEBP 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 WEBP files?

WebP is an image file format released by Google in 2010 with the aim of challenging the leading positions of JPG and PNG in the domain of storing and transferring digital images. The purpose of the WebP format is to improve the speed of browsing by offering the same quality as JPEG or PNG, but in a smaller size. WebP images can contain both lossy and lossless compression. They continue, however, to be incompatible with some image viewers and browsers, and are often described by analysts as "work in progress" — a format that still needs to be developed.
