Frequently asked questions
Are molecular files uploaded?
No. File text is read locally by your browser and rendered on-device.
Does XYZ contain bonds?
No. XYZ stores elements and coordinates. The viewer may infer visual bonds for display, but Toolardo does not use XYZ as a source for conversion back to SDF, MOL2 or PDB.
