Technical note

Before you convert CZI to PNG

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. PNG 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.

I design stickers but could never cleanly resize my PNG logos without pixelation. reaConverter’s PNG-to-SVG tool keeps everything sharp—even when scaling up. My Etsy shop looks way more professional now!

I love that reaConverter can convert PDF pages to individual PNGs. I used it to extract images from a scanned document – each page became a high-res PNG with zero loss. It's like magic, but it actually works every time.
