How to compress a video for Instagram Reels

Instagram’s documented ceiling is about 4 GB, but Reels and Stories under ~10 minutes often stall or fail above roughly 650 MB. Creators hit that practical cap more than the paper limit.

This preset is a free Instagram video compressor aimed at ~650 MB so the upload finishes. Crop to 9:16 first if the source is landscape. Nothing is uploaded to Shrink Clip.

If you only post Stories from a phone that already re-encodes, you may not need 650 MB — use Custom or TikTok 72 MB for a much smaller file that still looks fine on a phone screen.

How to compress a video for free

Three steps. The encoder runs on your device, so private clips never sit on a server.

1

Drop the video

MP4, MOV, WebM, AVI, or MKV. The file is read in this tab — it is never uploaded.

2

Pick a size cap

Discord 25MB, WhatsApp 16MB, email 20–25MB, X 512MB, TikTok, Instagram, or a custom MB. Bitrate is calculated, not guessed.

3

Download the MP4

Two-pass H.264 in the browser. No watermark, no account, no daily limit.
