Upload a file and inspect its hexadecimal and ASCII content in on-demand chunks, with offset jumps, byte-sequence search and common file format detection.
FAQ
Are uploaded files sent to a server?
No. Files are read locally by the browser and shown in chunks. Nothing is uploaded, so it is safe to inspect files from unknown sources.
Which formats are detected? How are large files handled?
File headers reveal common types such as JPEG, PNG, PDF, ZIP, MP4 and SQLite. Content loads in 4KB chunks with a 64KB view limit; use offset jump to reach any region.
All data is processed locally in your browser. Nothing is uploaded.
