Prepare a clip for its next destination
MP4 uses H.264 video and AAC audio; WebM uses VP9 and Opus. Choose a longest-edge limit to reduce resolution while keeping the display aspect ratio. Start and end times let you export just a section.
A 1920 × 1080 clip at a 1280 px limit becomes 1280 × 720.

AI generation has separate account and credit requirements.
Good to know
Can I convert MOV to MP4?
You can select MOV, MP4, WebM and other supported containers. The codecs inside the file must be decodable by your browser; a supported filename extension alone is not enough.
Does the video keep its sound?
Keep audio is enabled by default. The first audio track is included when present. Unsupported audio produces an error instead of silently disappearing. Files are limited to 250 MB and 15 minutes.
Do my files get uploaded?
Your chosen files and entered text are processed in this browser. They are not uploaded to Montagea. Signing in verifies your account. AI tools download models; image-to-prompt downloads its pinned model files from Hugging Face.
Is the download free?
Yes. Sign in with your Montagea account to use these tools, copy results and download files. They cost no credits and add no watermark.
