| Spec score · Game Asset Extractors | 7.7 (#11) | 8.3 (#4) |
| Purpose | Game Asset Tool extracts, collects, previews and diagnoses assets from visual novels and indie games. | Source 2 Viewer browses VPK archives and views, exports, and decompiles Source 2 assets such as maps, models, materials, textures, and sounds. |
| Security | The maker’s repository says built-in ZIP, JAR, NWJS, ASAR and RGSS extraction rejects absolute paths and path traversal entries and enforces extraction limits. | The repository says free code signing is provided by SignPath.io, with a certificate from SignPath Foundation. |
| Support | The maker says users can optionally donate on itch.io or support development on Ko-fi. | The maker directs users to report issues and notes that reports with a file path and error message usually get looked at quickly. |

In their own words
Game Asset Tool
Game Asset Tool scans a game folder or supported file, then extracts assets detected for its engine. It is a free Windows tool for collecting, previewing and diagnosing assets from visual novels and indie games, with batch extraction available. Built-in workflows cover RPG Maker, Ren’Py, NWJS, Electron, Unity, Godot, KiriKiri, WOLF RPG, TyranoScript, Java/JAR, HTML, QSP and Android APK recovery. Experimental or recovery workflows extend to Unreal PAK, Flash SWF, RAGS, GameMaker data.win, SRPG Studio, Pixel Game Maker MV, SPAK and some unknown formats. Results appear in a searchable gallery with filters, grouping, thumbnail presets and a resizable preview. The tool can create HTML reports that summarize extraction, diagnostics, skipped items, a health snapshot and performance notes. It handles images, video, audio, meshes and loose media, including OBJ models and PNG, JPEG, GIF, WebP and TLG5 textures. The maker says extraction works offline and the tool has no telemetry; BepInEx downloads need internet access. Encrypted Godot PCK archives need a valid key, and some protected formats are not fully extracted.
Source 2 Viewer
Source 2 Viewer is a free, open-source tool for browsing VPK archives and inspecting or exporting assets from Source 2 games. It can search, extract, and create archives, including VPK versions from Source 1. Its renderer displays maps, models, physics, and particles with real-time lighting and animation playback. The tool also inspects textures, audio, shaders, and other Source 2 resources. Maps, models, physics, and animations can be exported to glTF 2.0, with material conversion and batch export; maps, models, and materials can be decompiled into editable formats for Hammer, ModelDoc, and Source 2 Workshop Tools. Texture tools cover channels, depth layers, mip levels, cubemaps, and HDR, with image export. Its audio player supports WAV, MP3, and Source 2 formats. The graphical interface is Windows-only, though the guide describes running it on Linux and macOS through Wine; the command-line utility is available for Windows, Linux, and macOS. The GUI is portable and requires no installation. Some data may be lost during export, and reverse-engineered format support is incomplete. The project is volunteer-built and says it is not affiliated with Valve.
