Why Use This Tool
One processing pass on our servers — no queue behind other people's renders.
The file you download is the file, clean.
Upload from the camera roll and download straight back to it.
H.264 MP4 that plays everywhere, unless you chose another format.
Yes — no account, no watermark. Without an account you can process 3 videos a day up to 100MB each; a free account raises that to 20.
The video is re-encoded once at a high-quality setting (H.264, CRF 23), which is visually lossless at social-media sizes. Nothing is upscaled.
No. Upload, process and download without signing up. With a free account, video results are also saved to a Tools project in your dashboard.
ShortsHero turns long videos into short vertical clips with AI moment detection, face tracking and animated captions — and has free tools for subtitles, transcripts and video formats.
The same transcription powers ShortsHero's clip maker: it finds the strongest moments, reframes them to vertical and adds word-by-word captions in 36 styles.
