Technical note

What changes when you convert GEOJSON to AVIF

A GEOJSON file holds geometry and an attribute table, and nothing at all about appearance. Colours, line weights, fills and labels are properties of the GIS project rather than of the file, which is why the same GEOJSON looks different in every program that opens it. The AVIF render therefore falls back on defaults and will not match the styled map you see in QGIS or ArcGIS. Expect a clean drawing of the geometry rather than a finished cartographic product. GEOJSON coordinates are positions on the earth, tied to a stated reference system, and each feature carries its own row of attributes. AVIF is a picture: the coordinates become pixel positions and the attribute table is dropped entirely. That is fine for illustration and no use as data, so keep the GEOJSON original if anything downstream needs to query or reproject the features.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to AVIF with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • 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.

Twitch thumbnails keep saving as AVIF and my editing software freaks out. reaConverter swaps them to JPEG instantly. Now I can actually post my ‘🔥HOT TAKES🔥’ without crying over file errors.

Google Photos auto-saved my pics as AVIF files that won’t open anywhere. reaConverter rescued 3 years of memories AND kept the quality. Take that, ‘innovation’!

FAQ

GEOJSON to AVIF Conversion

What are GEOJSON files?

GEOJSON is a format for storing geographical data, compatible with several GIS programs. GEOJSON is a specialized version of JSON (Java Script Object Notation), an easy-to-use interchange format containing basic formatting rules for representing data, functioning as an alternative to XML. JSON files can be viewed with any text editor and are generally small-sized.

What are AVIF files?

AVIF is a new image format launched at the end of 2020. AV1 Image File Format was developed by the Alliance for Open Media in collaboration with Netflix, Google and Cisco. This format was created to be an open-sourced and royalty-free image format with a super-compression efficiency. Multiple graphics compression tests show that the .avif format outperforms the JPEG, PNG and WebP image formats for its image quality to compressed file size ratio.
