Reduce Video File Size for Instagram
Instagram has strict file size and resolution limits for feed posts, Reels, and Stories. Reclip's Video Compressor reduces your video file size to fit Instagram's requirements — directly in your browser, no software needed.

Why use it
Instagram rejects videos that exceed its file size limits, and large files often fail to upload or get heavily re-encoded by the platform. Compressing before upload keeps your video quality under your control and ensures faster, reliable uploads.
Supported formats
Input: MP4, MOV, AVI, MKV. Output: MP4 optimised for Instagram upload.
Frequently asked questions
Clear answers to get you started fast.
What is Instagram's video file size limit?
Instagram feed videos and Reels support up to 4GB, but files over 1GB are often re-encoded aggressively. Keeping your file under 500MB gives the best quality after Instagram's processing.
What resolution should Instagram videos be?
1080×1920 (9:16) for Reels and Stories; 1080×1080 (1:1) for feed posts. Reclip compresses at your chosen resolution.
Will compressing reduce Instagram video quality?
Some quality loss is unavoidable, but compressing before upload is better than letting Instagram re-encode a large file with its own aggressive settings.
Does it work on mobile?
Yes. The compressor runs in any mobile browser — no app installation needed.
