Uploading a score

Supported formats, size limits, and what to do when a file is rejected.

Supported formats

FormatExtensionWhen you have one
MusicXML.musicxmlThe default export of MuseScore, Sibelius, Finale and Dorico
MusicXML.xmlOlder exports, and programs that use the generic extension
Compressed MusicXML.mxlA zipped MusicXML document: smaller, and what most sites offer for download

All three are the same music. A .mxl file is a .musicxml file in a ZIP container; Annotune unpacks it for you.

How to import

  1. Open New score from the sidebar.
  2. Drop the file onto the upload area, or click it to open your file browser.
  3. Annotune checks the file type, its size and the structure of the document.
  4. The editor opens with your score in it.

If you would rather paste the document than upload it, choose the manual-entry link below the upload area and paste the MusicXML text.

Limits

  • A single score may be up to 5 MB of MusicXML.
  • A .mxl archive may be up to 6 MB, and must unpack to no more than 6 MB.
  • All your scores together may use up to 100 MB.

If your file is rejected

MessageWhat it means
That file type is not supportedThe extension is not .musicxml, .xml or .mxl. Re-export from your notation program as MusicXML.
This file is not a MusicXML documentThe file is XML, but not a score. A MusicXML document starts with score-partwise or score-timewise.
This MusicXML document could not be readThe file is damaged, or it uses a document type declaration, which Annotune refuses for security reasons.
This .mxl archive could not be openedThe ZIP is damaged, or it contains no MusicXML document.
You have used all your score storageDelete a score you no longer need from the Library, then try again.
Annotune refuses documents that declare an XML DOCTYPE. That is a deliberate restriction: it is the mechanism behind entity-expansion attacks, and no MusicXML file needs one. Re-exporting from your notation program produces a file without it.
