Are colors and units kept?
ASC stores only the coordinates of the points as plain text: no units, no mesh and, in its simple form, no colors. Check the scale of the points after conversion, and keep the source file if you need its colors, intensity or other attributes later.
Is there a file size limit?
There is no fixed limit on this page, but the web app works within your browser's memory: up to about 4 GB, or 16 GB in browsers with 64-bit WebAssembly. For very large models, or many files, use the desktop app for Windows, macOS or Linux.
