What OpenPRF is

OpenPRF is a browser-based editor for decrypted PS4 and PS5 save files, particularly PRF profile files. It decrypts and re-encrypts the inner PRF layer with TripleDES and can edit set, seta, sets, and bind commands. Users can load 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 are parsed for metadata; image and text files have supported previews or editing, while other file types are limited to Hex and Info tabs. Users can download one file or export a loaded save folder as a ZIP. Editing runs in the browser, with save files held in memory and downloads created locally; editing works offline, and Google Fonts is optional. OpenPRF does not handle the outer save-container encryption, which must be removed before loading files and restored after export. Most games reject PRF files whose editable text region exceeds roughly 1000 bytes. The project is MIT-licensed and requires no installation, build step, or account.

Who it suits

It suits PS4 and PS5 players who want to inspect or edit compatible decrypted save files in a browser. Users need to handle the outer save-container encryption separately.

What it does well

Edits PRF commands with TripleDES processing
Previews images and reads game metadata
Exports a file or the save folder as ZIP
Save editing works offline
Requires no installation, build step, or account

What to know first

Outer save-container encryption must be handled separately
Most games reject editable text regions above roughly 1000 bytes
Other file types have only Hex and Info tabs

Limits

OpenPRF handles the inner PRF encryption layer only; users must separately decrypt and re-encrypt the outer save container. Most games reject PRF files when the editable text region exceeds roughly 1000 bytes.

Getting started

Open the OpenPRF website in a modern browser.
Decrypt the save container’s outer encryption separately before loading its files.
Drag and drop the save folder, or use a folder or multi-file picker.
Edit compatible PRF files and inspect supported metadata, images, or text.
Download an individual file or export the loaded folder as a ZIP.
Re-encrypt the outer save container after exporting.

Verdict

OpenPRF provides local, offline-capable editing for decrypted PS4 and PS5 saves, with PRF editing and ZIP export. Users need to manage the outer container encryption themselves, and larger editable text regions may be rejected by most games.
