You can download many notes at once as a zip file. This zip file contains a separate zip file for every downloaded note. In it you will find the note itself as html and all the images, audio, video and text files which were uploaded to your original note.
You can download notes as archive on the NotezApp website. To download as archive, in your note list just select all the notes you need, click the download button in the navigation menu and then “Download as archive” option from its drop-down.
