Compress a video for Instagram reels, stories and feed. Free, no upload, no signup. SammaPix re-encodes your MP4 to upload faster and look sharp, right in your browser.
Big files upload slowly and Instagram re-compresses them anyway. Compress to a clean 1080p MP4 first so it uploads fast and keeps its quality.

Instagram prefers MP4 with the H.264 codec at 1080p. SammaPix outputs exactly that by default, so your reels, stories and feed posts upload cleanly and avoid extra re-compression by Instagram.
Drop your clip, keep the 1080p downscale on for 4K footage, and pick the balanced quality preset. SammaPix re-encodes it locally and shows a before and after compare before you download.
No. Everything runs in your browser with WebCodecs. Your video never leaves your device.
Smaller files upload faster and, by giving Instagram a clean 1080p MP4, you reduce how much its own compression degrades the final result.
