Auto Short CreatorTurn 16:9 videos into vertical 9:16 shorts

Auto Short Creator converts your horizontal 16:9 videos into vertical 9:16 videos ready for TikTok, YouTube Shorts and Instagram Reels, right in your browser. Who is it for? Content creators, streamers, video editors and agencies who repurpose long videos (gaming, podcasts, tutorials, interviews) into short formats without going back to a video editor. How it works Drop in a video, mark out extraction zones (the webcam, the game, the chat…) and place them freely in the vertical layout. The preview updates in real time, and the background is filled with a blurred crop of the original video. Features • Extraction zones: crop, position, scale, rotation, opacity and rounded corners. • Per-zone colour correction, horizontal flip and speed (0.25× to 4×). • Text overlays, watermark and background music with fades. • Multiple synchronised video sources. • MP4, WebM or GIF export at 1080×1920, with trimming and segments. • PNG thumbnail. • Local and cloud templates, autosave, undo / redo. • French or English interface, light or dark theme. Your videos stay with you All processing (cropping, encoding, export) runs locally in the browser with FFmpeg.wasm: your video files are never uploaded to a server. Pricing Free to try (3 exports per month, watermarked), then Starter, Creator and Studio plans from €2.99 to €9.99 per month, about 33% cheaper when billed yearly.
