Note: If you intend to build this tool rather than just write a paper, consider using existing OMR engines like Audiveris, Oemer, or the MuseScore OMR plugin (available in MuseScore 4) as a backend and wrapping it with a web API. A true automatic PDF→MSCZ online converter does not yet exist at production quality—making your paper, or your software, a valuable contribution.

Converting a PDF directly to an .mscz (MuseScore) file is a multi-step process because PDF files are "dumb" graphical formats that must be interpreted into "smart" musical data using Optical Music Recognition (OMR).  Top Recommended Converters 

MuseScore Import PDF Service: This is the official, free online tool provided by MuseScore. You upload your PDF, and it uses an OMR engine (Audiveris) to process it. You will receive an email once the conversion is done, and you can then download it as an .mscz file.

ACE Studio PDF to MusicXML: This tool converts your PDF into a .musicxml or .mxl file. Since MuseScore can natively open MusicXML, you simply open the resulting file in MuseScore and save it as an .mscz.

pdfFiller: A general-purpose document tool that claims to support direct conversion to the .mscz format online.  Alternative Desktop & Manual Methods 

If online converters give you messy results (which is common for complex scores), these methods are more reliable: 

Audiveris (Desktop): A powerful, open-source OMR software. You can process the PDF locally and export it as MusicXML to open in MuseScore.

ScanScore: A professional paid tool that specializes in high-accuracy scanning and importing directly into MuseScore.

Manual Transcription: For short pieces or very poor-quality PDFs, many users on Reddit suggest that transcribing the notes manually is often faster than fixing the errors generated by an automated converter. 

Pro-tip: For the best results, ensure your PDF is high-resolution (at least 300 DPI) and free of handwritten markings or coffee stains, as these confuse the recognition software.
