Resize Image for Instagram
Instagram supports up to 30MB but recommends 1080×1080 px for feed posts and 1080×1920 for stories. Files under 1MB upload faster on mobile data. Use our free tool to compress your photo for Instagram — works on mobile and desktop. Keep feed photos under 500KB for the fastest upload speed. All processing happens locally in your browser.
What You Need to Know
Instagram re-compresses every uploaded image regardless of your original quality. By pre-compressing with control over the quality level, you decide what gets preserved rather than letting Instagram's algorithm make that choice. For feed posts, square 1080×1080 images under 500KB consistently look sharp. Stories at 1080×1920 should stay under 1MB.
