OpenPRF
OpenPRF is a free browser editor for decrypted PlayStation 4 and PlayStation 5 save files, with a focus on PRF profile files.
What OpenPRF is
OpenPRF is a free browser editor for decrypted PlayStation 4 and PlayStation 5 save files, with a focus on PRF profile files. It can process the inner PRF encryption layer with TripleDES and edit set, seta, sets, and bind commands. Users can load save folders by drag and drop or with folder and multi-file pickers. The editor previews images, displays raw hex and file metadata, and reads game details from param.sfo and icon0.png. SFO files provide metadata; image and text files have supported previews or editing, while other files are limited to Hex and Info views.
Users can download an individual file or export a loaded save folder as a ZIP. Save files remain in browser memory, edits run client-side, and downloads are generated locally. Editing works offline; Google Fonts is optional and is the only listed network request. No installation, build step, or account is required to use OpenPRF in a modern browser. It does not handle the outer save-container encryption, which must be decrypted before loading and re-encrypted after export. Most games reject PRF files whose editable text region exceeds roughly 1000 bytes. The project is licensed under MIT.
