Technical note

Before you convert ASC to AVIF

Every cell in an ASC 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. AVIF 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 AVIF returns a shade, not an altitude. ASC carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. AVIF 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 ASC original if the data still has to go back into a GIS.

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’!
