What happens to your file
The file is read and converted in your browser and never leaves your computer. The score opens in the editor as an unsaved draft: play it, change it, transpose it. Press Save to keep it in your library; you can do that as a guest, without an account.
To combine files, open the first one, then choose ⋯ → Import another score as instruments… to add the parts of a second file to it.
Then export it
Every score can be exported as PDF, PNG, Guitar Pro, text tab, MusicXML, MIDI, MP3 or WAV, so SimpleNotation also works as a converter between these formats. Compare the export formats.
