What is A-Packets?
A-Packets is an online PCAP file analyzer that lets users explore and analyze network traffic, extract files, detect devices, investigate DNS/ARP packets, and view SSL/TLS sessions. It also supports credential detection and offers an automation API. See subscription plans.
What file formats does A-Packets support?
A-Packets supports .pcap and .pcapng formats, commonly used for network packet captures.
Is this service free?
Yes, it's free for files up to 25 MB. No registration or payment is required for basic analysis.
What information is shared when uploading?
Everything stored in the PCAP file. Please review the privacy policy before uploading.
Can I view HTTP headers?
Yes, you can explore full HTTP communication: requests, responses, form data, and headers.
Can A-Packets detect services and ports?
Yes, using passive fingerprinting it identifies services and open ports.
Can I find devices on the network?
Yes, A-Packets visualizes communication between nodes and classifies them by type and role.
Can I gather Wi-Fi information?
Yes. You can view SSIDs, access points, and probe requests, and detect multicast traffic.
Can A-Packets extract files?
Yes, it can extract images, office files, and others embedded in captured traffic.
Can I find passwords in PCAP files?
Yes, A-Packets detects plaintext credentials, hashes, and authentication handshakes across many protocols.
Does A-Packets support automation?
Yes, with an API that enables PCAP uploading, scheduled analysis, and integration.
Does it analyze SSL/TLS traffic?
Yes, it extracts session metadata, identifies anomalies (e.g., expired certs), and shows cipher and IP details.
How long does analysis take?
Typically 15–20 seconds depending on server load and file complexity.
What makes it better than other tools?
A-Packets is web-based, fast, and shares results as graphs and structured reports. It supports HTTP, FTP, Telnet, SIP, and more with no local setup.
How can I remove uploaded files?
Private files can be deleted by you. Public files can be removed via the contact form.
Why register?
Registration enables private uploads, file management, and larger file sizes depending on your pricing plan.
What happens when I subscribe?
Your card is charged immediately for the first billing period (monthly or yearly). You’re then billed automatically on the same calendar day every period unless you cancel.
Can I cancel anytime?
Yes. Cancelling stops future renewals, but you keep all subscription features until the current period ends. No prorated refunds are applied.
Do unused “runs” or private-file slots roll over?
No. Your analysis-run quota and private-storage slots reset on the first day of each new billing cycle.
What is a Pack?
A Pack is a one-time bundle of analysis credits, each good for one private run. Packs have their own file-size limit (25 MB, 50 MB, 100 MB, etc.).
How long do Packs last?
Packs expire 6 months (180 days) after purchase. Unused credits disappear on the expiry date.
What if I upgrade my subscription—do my Packs disappear?
No. Packs sit on top of any subscription and are consumed only when your subscription limits are full or a file exceeds your plan's size limit.
How long are Pack-based reports stored?
Private reports generated with a Pack are kept 30 days from the time of analysis. After 30 days they're automatically deleted.
Does deleting a report give me the credit back?
No. A credit is consumed when the analysis completes, regardless of whether you later delete the report.
Can I extend the 30-day retention?
Yes. Upgrade to a subscription with permanent private storage, or download the report before the 30-day window ends.
