Most online tools force you to upload your sensitive files to a remote server. We took a different approach. SwiftCompress uses advanced WebAssembly to optimize your files entirely inside your own browser.
Your photos, confidential documents, and personal videos never touch our servers. Processing happens in your local RAM.
No waiting for heavy files to upload or download. The compression begins the very second you select your file.
Completely free to use. No sign-ups, no watermarks, and no artificial daily limits blocking your workflow.
Instagram has strict video requirements: feed videos must be under 100MB, Stories under 30MB per clip, and Reels support up to 1GB but optimal uploads are 50–100MB. If your video is too large, Instagram either rejects it or applies heavy compression — turning your crisp content blurry. This guide shows you how to compress video for Instagram perfectly, free.
| Format | Max Size | Recommended Quality |
|---|---|---|
| Feed Video | 100MB | 70-80% |
| Stories | 30MB/clip | 60-70% |
| Reels | 1GB (aim 100MB) | 75-85% |
When you upload a raw video, Instagram applies its own aggressive re-compression algorithm. This results in visible banding, color loss, and motion artifacts. By pre-compressing your video with SwiftCompress at 70–80% quality, you control the output. Instagram then has much less to recompress, leaving your video looking significantly sharper.
