Resize Images for Instagram
Instagram-perfect quality for feed posts (1080×1080) and stories/reels (1080×1920).
Your images stay on your device. Nothing is uploaded.
Instagram re-encodes every upload, so starting from a clean, correctly sized JPEG keeps your final image as sharp as possible. The compressor is pre-tuned for an Instagram-ready JPEG at q85.
For exact platform crops, the dedicated social media cropper is linked below. Compression here keeps the image at standard Instagram dimensions while reducing file size.

Frequently asked questions
- What size should an image be for Instagram?
- Instagram recommends 1080×1080 for square feed posts, 1080×1350 for portrait feed posts, and 1080×1920 for stories and reels. The compressor on this page is pre-tuned to those dimensions and the recommended quality.
- Why does Instagram compress my images again after upload?
- Instagram re-encodes uploads to its own internal format and bitrate. Starting from a clean, correctly sized image avoids two rounds of lossy compression and keeps your final image sharper.
- Does this tool actually post to Instagram?
- No — it prepares the file. Download the result and upload it to Instagram as you normally would. Keeping the posting flow inside Instagram is safer and respects their terms of service.
- What format should I use for Instagram?
- JPEG is the safest universal choice for Instagram uploads. Some platforms accept WebP and PNG, but JPEG is always supported and is what the defaults on this page use.
- Are my images uploaded anywhere when I use this tool?
- No. The resize and compression happen in your browser. The file only leaves your device when you upload it to Instagram yourself.
