Instagram Reel Size 2026: How to Resize and Compress Your Video
Instagram tightened up its video story in 2026: Reels look their best at 1080 × 1920 pixels, a 9:16 aspect ratio, exported as MP4(H.264, 30 fps). Upload something off-spec or too large and Instagram re-compresses it hard, leaving your Reel soft and blocky. Here's how to hit the spec exactly — for free, with nothing uploaded to a third-party server.
Get your clip to 1080×1920, 9:16
- If your video isn't vertical, open the crop tool for stills or reframe your footage to a 9:16 vertical frame in your editor so the subject stays centered.
- Need a different container? Use the video converter to turn MOV, MKV, or WebM into the MP4 Instagram prefers.
- Open the video compressor and drop your clip in.
- Pick a target size or quality level, then export. The output is a clean MP4 — no watermark — ready to upload.

Why compress instead of letting Instagram do it
Instagram will always re-encode your upload. If you hand it a bloated file, it compresses aggressively and the result looks worse. Hand it a clean, correctly-sized MP4 and the platform's pass is gentler — your Reel stays sharp. Compressing first also means faster uploads on mobile data and no more “file too large” failures.
