[ EXECUTION PROTOCOL ]

How to Convert PSU to ZIP Locally

  1. PHASE 01 // STAGE SOURCE

    Load .psu Payload

    Drag and drop your .psu file onto the working surface or use the system file dialog. File magic bytes are verified locally on device.

  2. PHASE 02 // CONFIGURE

    Set Codec & Quality Parameters

    Select a quality preset (Lossless, Visually Lossless, Balanced, Smallest) or adjust advanced encoding switches in the options panel.

  3. PHASE 03 // COMPILE & EXPORT

    Export .zip to Disk

    Click CONVERT to execute local WebAssembly compilation. Save the finished .zip directly to local storage, or stage it for chaining.

Technical Details & FAQ

[?]What is a PlayStation 2 .psu file?

A .psu file is an EMS / uLaunchELF container that packages an entire PlayStation 2 memory card save folder (such as BASLUS-21441GTA containing icon.sys, icon.icn, and save.bin) while preserving PS2 filesystem permissions and timestamps.

[?]Can this unpack saves for PCSX2 and AetherSX2?

Yes. The generated ZIP archive contains the exact folder structure required by PCSX2's Folder Memory Card format and AetherSX2 save managers.

[?]Does this require installing legacy Windows tools?

No. Unlike legacy 32-bit Windows software like PS2 Save Builder, convrtr runs 100% locally in your web browser across Windows, macOS, Linux, iOS, and Android.

[?]Why convert from PSU to ZIP?

PSU Document (PSU) and ZIP Document (ZIP) serve distinct roles across the digital workflow. Converting to ZIP provides optimized compatibility, modern compression efficiency, or standardized playback across web browsers, operating systems, and media production environments.

[?]Is the PSU to ZIP conversion lossless or lossy?

The output format (ZIP) is inherently lossless or supports lossless operation. Your original visual or audio fidelity is mathematically preserved without quantization artifacts.

[?]Does convrtr upload my files to any cloud server?

Never. convrtr is architected with a strict zero-upload model. All processing, decoding, decompression, and encoding happen 100% locally on your machine using sandboxed WebAssembly and Web Workers. Your data never touches an external server, database, or analytics collector.

[?]How can I convert PSU to ZIP from the terminal / command line?

You can execute this conversion locally via command-line utilities such as ffmpeg, cwebp, or ImageMagick. For example: see the developer terminal recipe provided in the technical specifications dossier above. convrtr provides the identical local-first capability directly inside your browser without installing CLI packages.

[?]Can I batch convert multiple PSU files to ZIP simultaneously?

Yes. You can drop multiple .psu files into the instrument to process them concurrently in browser Web Workers, or click 'Open in Master Studio' to queue mixed formats, configure individual targets, and export as a single ZIP archive.
