How do I convert a video for Instagram?
To optimize a clip, upload your source video to the Flixier dashboard and place it on the timeline. Adjust the Aspect Ratio to match the specific slot you are targeting, such as vertical 9:16 or square 1:1, and export the project as a web-optimized video file.
What video format does Instagram use?
The social platform primarily prefers standard MP4 containers compressed with the H.264 video codec and AAC audio parameters. Our online Instagram video converter processes your media automatically into these precise parameters to ensure immediate compatibility and fast processing.
What is the best aspect ratio for Instagram Reels?
The optimal layout configuration is a vertical 9:16 orientation, which translates to a standard resolution of 1080x1920 pixels. This framework occupies the entire display of mobile smartphones natively, maximizing visual real estate to catch scrolling users.
How do I resize a video for Instagram Stories?
Upload your video and use the canvas aspect ratio settings to pick the 9:16 preset layout. From there, you can scale your video up to fill the vertical frame or add background styling to fill the empty borders cleanly without losing important details.
Is the Instagram video converter free?
Flixier offers a completely functional free tier that runs entirely within your favorite web browser. This setup allows you to upload footage, adjust frame sizes, apply transitions or animated text overlays, and export social-ready media files without upfront software fees.
