よくある質問
Quick answers.
›What is the difference between hex and ASCII?
Hexadecimal represents each byte as a base-16 number from `00` to `FF`, while the ASCII view shows the printable character equivalent. Non-printable characters are typically represented by a dot in the ASCII column.
›Is my file uploaded to your server?
No. The editor uses the browser's File API to read and modify the data locally on your device. Your file data never leaves your computer.
›Can I edit large files with this tool?
Most files under 100MB will load smoothly, though performance depends on your device's available memory. For extremely large files, the browser may experience latency when rendering the full hex grid.
›How do I interpret the offset column?
The offset column on the left shows the memory address or position of the first byte in that row. It is usually displayed in hexadecimal to help locate specific data structures within the file.
