Compress a video for Instagram

Instagram re-encodes everything you upload and displays Reels and Stories at up to 1080 pixels wide, so uploading a huge 4K file mostly just wastes data and time — and big files are more likely to stall on mobile. Converting to 1080p H.264 MP4 at a sensible size gives Instagram a clean source to work from.

How to do it

  1. Open the compressor with 1080p resolution and a 100 MB target (the button below sets both).
  2. Load your video. 4K phone footage and camera MOV files are fine.
  3. Trim it to your Reel or Story length.
  4. Compress and download the MP4.
  5. Upload it in the Instagram app as usual.

Tips

FAQ

Does compressing first improve Instagram quality?

It mainly makes uploads faster and more reliable. Quality is set largely by Instagram's own encoding; a clean 1080p source avoids extra damage from downscaling on their side.

Will it crop my video to 9:16?

No. Resolution scaling keeps the original aspect ratio. Crop in your editor or the Instagram app.

Is my video uploaded to your server?

No — it's compressed on your device. It's only uploaded when you post it to Instagram yourself.
