Input
Paste Hex or Base64, or choose a binary payload file. Hex accepts spaces, line breaks, colons, commas, and 0x prefixes.

Parsed fields retain byte offsets and lengths. Selecting a field highlights its corresponding bytes and shows the decoded value.
Handle with care
Parsing sends the current data for processing. Do not submit credentials, keys, personal records, or sensitive production traffic.
PROTOCOL REFERENCE
About WebSocket packet parsing
Inspect WebSocket packet bytes in a focused network protocol workspace. The page exposes text, binary, and control frames after connection, preserves byte offsets, and lets you compare field values with the original Hex, Base64, or binary payload.
01Paste a captured WebSocket payload as Hex or Base64, or open a binary file to keep the original byte sequence intact.
02Select a field to highlight its exact byte range and inspect the decoded value, type, offset, and length.
03When you need a test fixture instead of an existing capture, open the WebSocket packet generator to compose a new payload.
Frequently asked questions
What does this WebSocket parser show?
It displays the decoded WebSocket fields together with byte offsets, field lengths, values, and the corresponding hexadecimal bytes.
Can I inspect a WebSocket capture without converting it first?
Yes. The parser accepts Hex, Base64, and binary files, so a payload extracted from a capture can be inspected directly.
