 - Save to file and load from file
-     - You can save the output to a file at any time or load a file by dragging and dropping it into the input field (note that files larger than about 500kb may cause your browser to hang or even crash due to the way that browsers handle large amounts of textual data).
+     - You can save the output to a file at any time or load a file by dragging and dropping it into the input field. Files up to around 500MB are supported (depending on your browser), however some operations may take a very long time to run over this much data.
 - CyberChef is entirely client-side
-     - It should be noted that none of your input or recipe configuration is ever sent to the CyberChef web server - all processing is carried out within your browser, on your own computer.
