Extract text from OneNote packages (ONEPKG)
To convert ONEPKG packages to another format, you need Microsoft OneNote or other Backup software.
To convert other file formats to the "Notebook Archive Package" file type, you need software like Microsoft OneNote or a similar tool.
A .onepkg file is a Microsoft OneNote Package used to back up or share an entire digital notebook. It acts as an archive, bundling multiple notebook sections (ONE files), index files (ONETOC2), images, and embedded attachments into a single portable file.
This is a proprietary archive format. The main disadvantage of a .onepkg file is that it strictly requires the classic desktop version of Microsoft OneNote to open. Users cannot view it in a web browser, and lightweight or mobile versions of OneNote (including OneNote for Mac) completely lack the ability to import local package files. Furthermore, because it is a compressed container holding proprietary section files, standard document converters consistently fail to process it.
Users typically need to convert this file to a PDF for universal reading or extract it to ZIP or CAB to access the internal ONE files and raw image attachments without needing a Microsoft 365 subscription.
Because this format is closed and tied to the Microsoft ecosystem, full structural conversion without the original software is difficult. Our system can inspect the underlying Microsoft Cabinet (CAB) structure, allowing you to bypass the OneNote lock-in and access the raw data, text, or media inside when possible.
Convert.Guru analyzes your ONEPKG file, detects the exact format, and lets you read the text inside.
Users also converted ONE, DOCUMENT FROM PRATYUSH, ONETOC2, PDF, ZIP, URL, PKG, SDOCX, NOTE, ASC, TXT, EXE and NUPKG files.
If you want to convert ONEPKG file to PDF, ONE, ZIP, BAK, BACKUP, OLD, TMP, TEMP, ARC, TAR, GZ or 7Z, you can use Microsoft OneNote or similar software from the "Notebook Backup and Sharing" category. In the File menu, look for Save As… or Export….
To convert SNAPSHOT, OLD, IMG, RESTORE, ISO, COPY, VMDK, TMP, VHD, BAK, ARCHIVE or BACKUP files to ONEPKG, try Microsoft OneNote or another comparable tool in the "Notebook Backup and Sharing" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ONEPKG converter.
