Base64 / Hex Network Packet Decoder

How to use Base64 / Hex Network Packet Decoder

Paste hexadecimal or standard Base64 bytes up to 64 KiB decoded. Choose the known starting layer, or use heuristic auto detection. Inspect decoded headers and a hex/ASCII preview; export complete JSON. Checksums are displayed without verification. This is not packet capture, PCAP parsing, decryption, stream reassembly or application-protocol analysis.

Is this tool free?

You can complete three tools as a guest across this collection. Continue with Google for further use. Failed operations do not consume a successful use.

Where is my content processed?

Input bytes and pasted ARP tables remain on your device. The server receives only the tool and operation outcome for the existing usage limits; no capture traffic or pasted table contents are uploaded.

What does the result mean?

Reports describe observed responses or the structure of your supplied bytes/table. Results do not establish site security, validate packet checksums or prove ARP spoofing. Read the tool-specific assumptions and any incomplete-result warnings.
