Demystifying Game Save Files Safely
SaveLab is a free, 100% client-side tool designed to help PC gamers inspect, verify, and safely edit offline save files directly in the browser.

Selected save files are parsed exclusively within your browser's local memory. There are no file upload APIs, no remote databases, and no user accounts. The moment you close or refresh the browser tab, all session memory and modified data are instantly discarded.
Strict Safe-Editing Guarantees
SaveLab exposes intuitive editors for structured formats such as JSON, XML, YAML, and SQLite. If a file uses proprietary encryption, undocumented compression, or signed checksums that cannot be safely reconstructed, SaveLab halts execution rather than guessing and risking save corruption.
Built-In Security Safeguards
Before parsing, strict limits are enforced: 64MB file cap, 96MB uncompressed ceiling, and rejection of dangerous XML entities, path traversal archives, or executable binary signatures. However, always create a standalone backup copy of your save before making any edits.
