About Byte Viewer
Byte Viewer shows a file's bytes as DECIMAL values (0–255) — an offset followed by 16 bytes per line. Useful when you need byte values in decimal rather than hex.
The view is capped at the first 256 KB. Read in the browser, no upload.
FAQ
Is my file/data uploaded to a server?
No. Everything is opened and rendered in your browser with JavaScript (the File API). Nothing is uploaded, logged, or stored on our servers — safe for sensitive files.
How is this viewer different from an extractor or parser?
A viewer shows the content as-is (read-only) — you see the file/text the way it is. An extractor pulls raw data (e.g. text from a PDF) into a string, while a parser breaks input into its component structure. A viewer focuses on "see", not "transform" or "pull".
