Technical note

Before you convert CZI to GIF

CZI is an N-dimensional acquisition rather than a picture. One file can hold several fluorescence channels, a stack of focal planes, a time series and a mosaic of stitched tiles, each recorded separately by the camera. GIF is a flat image format, so those dimensions have to be resolved into ordinary pictures, and which result is the right one depends on the work: a merged colour composite suits a figure or a presentation, while separate greyscale planes are what quantification needs. A scientific camera records 16 bits per pixel, and the signal of interest often occupies a narrow slice of that range, while GIF shows 8. Conversion applies a display mapping, so two acquisitions that look identical afterwards can hold very different underlying intensities. Treat the GIF output as something to look at and publish rather than something to measure.

I firmly believe working with JPEG — the universal format supported by all devices and apps—is the wisest choice. reaConverter handles these conversions flawlessly.

FAQ

CZI to GIF Conversion

What are CZI files?

CZI (Carl Zeiss Image) is the native image format of ZEISS ZEN microscopy software. It stores multidimensional acquisitions with channels, z-stacks, time series and mosaic tiles, together with the full set of instrument and acquisition metadata.

What are GIF files?

GIF (Graphics Interchange Format) files are widely popular due to their ability to store animations and images in a relatively small size. Their compression algorithm implies the use of a limited color range (up to 256 colors), which means GIF files are great for storing static and animated images of a small size — like logos, icons or avatars, especially if you plan to transfer them or upload them online. GIF images, however, are usually not suitable for high-quality image rendering or printing.
