Scientific questions
Answers that apply across this category.
Is precision preserved?
Numeric arrays are converted without lossy rounding. Very large arrays are the main limit, since they must fit in your device's memory.
Working with scientific files
Convert research data between common scientific formats so it can be reused in analysis tools.
Conversions in this category are designed to run on your device wherever the browser makes it possible. Where a format needs a codec the browser does not ship, the tool downloads that codec as a WebAssembly module the first time you use it, and the page tells you before you start.
Nothing is uploaded for supported tools. If a future tool needs to process a file on a server, that will be stated on the tool page before you select a file, along with how long the file is kept.
