Spec score 8.0 #8 of 26 in Game Save Editors

What it is

OpenPRF is a web editor for decrypted PlayStation 4 and PlayStation 5 save files, with particular attention to PRF profile files. It decrypts and re-encrypts the inner PRF layer with TripleDES and lets users edit set, seta, sets, and bind commands. PRF files can be edited; SFO files provide game metadata, images and text have supported previews or editing, and other files are limited to Hex and Info views. The editor can preview images, display raw hex and metadata, and read game details from param.sfo and icon0.png. Users can load folders or multiple files, then download an individual file or export the folder as a ZIP. Editing happens client-side, with files held in browser memory and downloads created locally; the project says editing also works offline. It requires no installation, build step, or account. OpenPRF handles only the inner encryption layer, so users must separately decrypt the outer save container before loading files and re-encrypt it after export. Most games reject PRF editable text regions above roughly 1000 bytes.

Strong points and limits

Strong points

  • Edits PRF commands using TripleDES.
  • Previews images and reads SFO game metadata.
  • Exports individual files or save folders as ZIP.
  • Offline editing works without an account or installation.
  • MIT license allows use, modification, and distribution.

Limits

  • Outer save-container encryption must be handled separately.
  • Most games reject editable text regions above roughly 1000 bytes.
  • Chrome or Edge is recommended for the best folder loading.
  • Authors provide no warranty across games or firmware versions.

Who it suits

OpenPRF suits PS4 and PS5 players working with compatible PRF save files who want browser-based editing and inspection. Users need another method to handle the outer save-container encryption.

Verdict

OpenPRF covers PRF editing, file inspection, and local ZIP export in a browser, including offline use. Its outer-encryption requirement and the roughly 1000-byte editable-region limit are important constraints to check first.
