From Navy CERT to building ICE-Forensic, JeongKyun Park shares how a passion for uncovering the truth through system traces is driving his transition into digital forensics.
Read MoreIt visualizes raw binary data in hexadecimal format for deep inspection. Features include instant offset navigation and automatic data interpretation for various types like UInt, Float, and Time, providing a professional forensic analysis environment.
No. While the EXIF and chunk analysis features are optimized for image files, the Hex Viewer and Hash Calculator support all types of binary files, including executables (EXE), documents, and compressed files.
Yes, we support powerful search functionalities based on Text (ASCII), Hexadecimal (Hex), and Offset. It provides a case-sensitive option and allows you to instantly find desired data even in large files, quickly navigating up to 1,000 results.
We support all standard algorithms including MD5, SHA-1, SHA-256, and SHA-512 for verifying file identity and integrity. Large files are processed instantly via local WASM technology.
Yes. Utilizing WebAssembly (WASM) for efficient memory management, the tool can load and analyze files over several hundred MBs in real-time without browser freezing.
No, your original photos or file data are never stored on our servers. File analysis is processed 100% locally within your device (browser). However, only when you explicitly request features like 'Map View' or 'Show My IP', the minimum necessary data (GPS coordinates, IP) is temporarily sent to external APIs (like OpenStreetMap) to provide the service, and this data is also not stored on our servers.
Yes, extraction is possible in most cases. It scans and displays text data such as prompts, model details, and seeds recorded in iTXt or tEXt chunks within PNG files. You can check metadata generated from major platforms like WebUI, ComfyUI, and NovelAI, though some information may be missing depending on the image generation method or compression/conversion process.
Yes, it is possible because it uses binary stream scanning instead of standard image rendering methods. As long as the file header (IHDR) or metadata chunks remain intact, text information can be recovered even from broken images.
Yes, it perfectly analyzes eXIf and standard PNG chunks included in mobile device captures, providing detailed information such as device info, capture timestamps, and resolution.
Yes, it can be used instantly without any program installation on all devices (Windows, macOS, Linux, iOS, Android, etc.) that run a web browser. As long as you have an internet connection, it provides a powerful forensic environment anytime, anywhere.
Yes, we support a Multi-tab feature allowing you to open multiple files at the same time and switch between them for analysis. Additionally, once calculated, hash values and search results are automatically cached in the browser, so they are displayed instantly without delay upon re-checking.
✨ This web app works without installation, and is a static digital forensics web application that does not upload files or personal information to the server.
