reaConverter offers the fastest, simplest solution for converting your FIT files into PNG in seconds - all images processed on your PC for maximum privacy and speed.

Technical note

FIT to PNG: what to expect from the conversion

A scientific camera records 32 bits per pixel, and the signal of interest often occupies a narrow slice of that range, while PNG shows 8. Conversion applies a display mapping, so two acquisitions that look identical afterwards can hold very different underlying intensities. Treat the PNG output as something to look at and publish rather than something to measure. One FIT file can hold several pages or frames, while PNG holds one image each. reaConverter writes a separate output file per page and numbers them, so a single input can produce a whole folder of results.
