Adobe PDF

Adobe PDF files are commonly used as digital versions of paper documents. The PDF format faithfully reproduces the printed page. OnSong can view PDF files, vertically scrolling through multiple pages. OnSong expects each song to be contained in a single PDF file.

While PDF files maintain how a document should look, they can sacrifice meaningful text to do that. For instance, some PDF documents do not contain textural content but rather shapes and images. While this may appear as text to the human eye, it can be very difficult to extract from the document. OnSong attempts to do this when converting to text. If sufficient text cannot be extracted, OnSong will upload the document to an optical character recognition service (OCR) that will attempt to read the document using computer algorithms. This can have varying results depending on the original document.

OnSong can also view password-protected PDF files and will display a prompt for the password when viewed. Enter the password for the file and OnSong will retain that password along with the song so you don't need to enter the password multiple times during a performance.

PDF files are rendered using the PDF viewer provided by the operating system. Issues viewing imported files may be caused by iOS/iPadOS versions and updates.
