How the Video Meme Generator Works
AnyTool adds meme captions to a video entirely in the browser. Styled text — classic Impact captions or top/bottom white "caption bars" (iFunny / r/whenthe style) — is drawn on a canvas with bundled meme fonts and overlaid directly on the playing video for a pixel-perfect WYSIWYG preview. On export, the same canvas is rendered into a transparent PNG and composited over the video with the self-hosted ffmpeg engine (overlay filter), re-encoded to a universally-shareable H.264 MP4; a GIF export uses a two-pass palette for clean colors. Because the preview and export share the render code, the downloaded meme matches the screen exactly.
- Runs client-side — the video is never uploaded
- Classic Impact captions + white-box caption bars
- Bundled meme fonts for a consistent look on every device
- Universal MP4 (H.264) and clean GIF output
- Pixel-perfect WYSIWYG preview = export
- No backend, no watermark, no sign-up
