What dimensions should I use for Instagram Reels?

The tool defaults to 1080 × 1920 pixels, a 9:16 vertical frame. Check Instagram’s upload preview because captions, profile previews and interface controls can cover or crop different parts of the video.

How do I make a landscape video fit a Reel?

Choose 9:16, then Crop to fill for a selected vertical region or Fit whole video to keep the entire landscape frame with bars. Both options export an MP4.

Will this crop out my captions?

A crop can remove captions that are already part of the source image. Move the crop, use Fit whole video, or return to a clean master and add captions after resizing. Check the whole exported video.

Does this tool shorten a video for Instagram?

No. Resizing preserves the recording’s duration. Check the current duration allowed in your Instagram upload flow and trim or make a shorter clip if needed.

Is this free and does it upload my video?

Resizing is free and runs on your device without a watermark or account. The source limit is 512 MB. Codec support and available browser memory affect which files can be processed.

How to use it

Choose your source video

Select a video up to 512 MB. Wait for its preview so you can check what will appear in the vertical frame.

Crop or fit to 1080 × 1920

Choose Crop to fill for a full-height Reel, or Fit whole video to preserve all edges. Keep captions away from the frame’s bottom and sides.

Review the MP4 in Instagram

Download and play the full export, then check Instagram’s upload preview for framing, captions and the duration allowed on your account.

What you get

A 9:16 starting point

Export 1080 × 1920 for a vertical Reel. Use 4:5 for a separate portrait-feed version or choose another available shape.

Keep slides and products visible

Fit whole video retains the source frame with black bars. Crop to fill lets you choose a fixed region for full-frame output.

Preview the crop you selected

The first-frame export preview uses the same crop as conversion. It is a framing check; play the final export to check movement.

H.264 MP4 with sound

Export H.264 video and AAC audio when present. Unsupported video or audio tracks stop conversion instead of silently disappearing.

Questions

Choose a frame that keeps the useful content

Crop to fill

Useful for one speaker or product. Select a fixed region, then review the whole export in case the subject moves out of it.

Fit whole video

Useful for slides, tutorials and several speakers. Every source edge remains visible, with black bars around the unused space.

Resizing changes the frame and pixel dimensions. It does not shorten a recording, track a speaker automatically, or guarantee sharper detail.

Use the Instagram upload preview to check captions and framing. Duration options can differ by upload flow; this tool does not promise a fixed 90-second limit.
