Is it really free?+
Yes. Unlimited videos, no signup required for the tool itself, no credit card. The whole generator runs in your browser.
Does the video have a watermark?+
No. Output is a clean MP4 with no OneUp Today branding burned in.
Can I post these on TikTok or Instagram?+
Yes. The MP4 plays natively on TikTok, Instagram Reels, YouTube Shorts, X, and Facebook. The 9:16 phone framing is already optimized for short-form.
Will WhatsApp ban me for using this?+
No. The tool generates an image-only mockup using HTML canvas. It never connects to WhatsApp's servers and never touches your real account.
Is my data private?+
Yes. Every message, contact name, and frame is rendered locally in your browser. We don't upload anything to a server.
Can I download in HD?+
Yes. The output is a 540x1170 MP4 (2x retina) at 4 fps, suitable for direct upload to all major social platforms.
Is this a WhatsApp chat generator or only a video maker?+
It's a full WhatsApp chat generator. You build the conversation message by message, set the contact, theme, and timestamps, then the tool turns that chat into an animated video you can download. The chat generator and the video export are the same tool.
How do I make a fake WhatsApp conversation?+
Type each message and choose whether you or the contact sent it, name the contact, pick light or dark mode, then generate. The fake WhatsApp conversation plays back with typing animations and downloads as an MP4, no signup needed.
Does it create a chat animation or a static mockup?+
It animates. Messages and typing bubbles appear in sequence, so you get a moving WhatsApp chat animation rather than a flat mockup, then it exports as a short MP4. That movement is what makes it work as a video hook.
Can I customize the contact, theme, and timestamps?+
Yes. Rename the contact, switch between WhatsApp light and dark themes, and set custom timestamps so the fake WhatsApp chat matches a real conversation before you export the video.
