Frequently Asked Questions

Instagram Reels require 9:16 aspect ratio (1080x1920 pixels), MP4 or MOV format, H.264 codec with AAC audio, 30fps, and maximum 90 seconds duration. File size limit is 4GB.

Reels use 9:16 vertical (1080x1920) for up to 90s, Feed uses 4:5 portrait (1080x1350) or 1:1 square for up to 60s, and Stories use 9:16 vertical for up to 15s. Each format has different engagement patterns.

Yes, if your video's aspect ratio differs from 9:16. Horizontal videos will have top/bottom cropped or left/right padded. You can adjust the crop position to frame your subject optimally.

The tool will warn you and automatically trim to 90 seconds by default. You can choose which part to keep by adjusting the start time, or split your video into multiple Reels.

Yes, but horizontal 16:9 videos will be significantly cropped or padded to fit 9:16. For best results, either crop to focus on key content or add blur/color bars on the sides to preserve the full frame.

Instagram recommends 5Mbps video bitrate and 128kbps audio bitrate for Reels. Our tool uses these optimal settings to balance quality and upload speed while meeting Instagram's compression standards.

Yes, after the initial load of FFmpeg WASM library, all video processing happens in your browser. No files are uploaded to servers. You can use it offline once the page and libraries are cached.

Currently the tool processes one video at a time. Convert each video individually, download the optimized version, then load the next. This ensures browser stability with large video files.

Video encoding is CPU-intensive. FFmpeg WASM runs entirely in your browser, using JavaScript which is slower than native apps. Shorter videos (under 30s) process in seconds, while 90s videos may take 1-2 minutes.

Use 1080x1920 resolution, 30fps, H.264 codec with CRF 23 for balanced quality. Higher quality settings won't improve appearance on Instagram since it re-compresses uploads, but will increase file size and upload time.
