Convert HGT to TIF

Online GIS converters cap file size and need an upload. reaConverter converts HGT to TIF locally, whatever the size of the dataset.

Online converters too slow for your HGT files? reaConverter works locally and handles unlimited batches. All processing runs locally on your PC, so your files stay private and secure. No command line and no scripting, unlike the usual ogr2ogr route.

How It Works

reaConverter offers the fastest, simplest solution for converting your HGT files into TIF without GIS software - all files processed on your PC for maximum privacy and speed.

Technical note

How HGT and TIF differ in practice

Every cell in an HGT 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. TIF 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 TIF returns a shade, not an altitude. HGT files have no header. Each tile's position is encoded only in its name: N45E006.hgt is the one-degree square whose south-west corner sits at 45° north, 6° east. The resolution is read from the file size, 3601 by 3601 samples for 1 arc-second SRTM and 1201 by 1201 for 3 arc-second. A renamed tile can no longer be placed, or even recognised, so keep the original name on anything derived from it.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see HGT data has GIS software. reaConverter renders it to TIF for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to TIF 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.
