How to Make a Fake WhatsApp Group Chat Video or Screenshot

Vidulk’s free browser-based fake chat generator lets you build a WhatsApp group chat with multiple senders in just a few minutes. Here’s how to use the tool to create your own animated group chat video or screenshot:

1. Open the WhatsApp Fake Chat Generator: Scroll down to the embedded generator on this page. No download or account needed.
2. Set the Group Name and Status: In the 'Contact Name' field, type your group chat’s name (e.g., 'Family', 'the squad'). Add an 'online' or 'last seen' status for extra realism.
3. Add Group Members: Think of 3 - 5 distinct names for your group members. Each sender should have their own style or role (the joker, the latecomer, etc.).
4. Write Messages: For each received message, start with the sender’s name and a colon (e.g., 'Mia: no way'). Sent messages appear on the right (green bubble); received messages with names appear on the left (grey bubble). Keep messages short, overlapping, and lively.
5. Enhance Realism: Add timestamps, use single/double grey ticks or blue ticks for 'read' status, and try the typing indicator. Mix in side comments and let one member chime in late for extra group chat drama.
6. Preview and Export: Watch the animated preview. When ready, export as an MP4 video (great for TikTok, YouTube Shorts, Reels) or a PNG screenshot. Free exports have a small watermark, which you can remove with a one-time code.

Tips for Authentic Group Chat Storytelling

Distinct Voices: Make each sender’s messages sound different, using slang, emojis, or catchphrases.
Overlapping Messages: Have several members reply quickly, just like real group chaos.
Side Conversations: Let two members have a mini-chat inside the main thread.
Late Replies: Add a message from someone who’s always late to the joke or drama.
