Extract text from Pickle, Peak, and archive files (PK)
To convert PK Files to another format, you need Python or other Developer software.
To convert other file formats to the "Serialized Object or Peak File" file type, you need software like Python or a similar tool.
A .pk file is an extremely overloaded extension used across completely different software ecosystems. Most commonly, it acts as either an Adobe Audition Peak File, a Python Pickle Serialized Object, or a compressed archive originally tied to the PKWARE format. Because the extension is shared, opening a .pk file blindly often results in error messages or unreadable binary garbage.
When used as an Adobe Audition or Pro Tools peak file, it stores the visual representation of an audio waveform. The main disadvantage is that it contains no actual audio data. If you try to open it in a media player, it will fail. You do not need to back these up; if you delete a peak file, your audio editor simply regenerates it the next time you load the corresponding audio file.
When used as a Python Pickle file, it contains a serialized Python object tree. This format is notoriously problematic for sharing. It is highly version-dependent, proprietary to Python, and poses a severe security risk - loading an untrusted pickle file can execute malicious code on your machine. For safe data exchange, you must deserialize the .pk file and convert it to a universally readable format.
Other uses include packed game data (like the Pixelmon Minecraft mod or Unity asset bundles) and OpenSSH private cryptographic keys. Drag and drop your file to analyze and convert it - free, online, and without installing software. Our analyzer will detect the actual internal structure of your .pk file instantly.

If you want to convert PK file to HP, MP3, WAV, AAC, FLAC, OGG, WMA, M4A, AIFF, OPUS, ALAC or APE, you can use Python or similar software from the "Audio Caching or Serialized Data" category. In the File menu, look for Save As… or Export….
To convert MIDI, AAC, TTA, AU, WV, DTS, MID, FLAC, RA, MP3, PCM or WAV files to PK, try Python or another comparable tool in the "Audio Caching or Serialized Data" 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 PK converter.
