Why resize images for Instagram?
Instagram displays feed posts at 1080 pixels wide. Using the correct dimensions ensures your images look sharp and aren't cropped unexpectedly. Square posts (1080×1080) work well for product shots and portraits. Portrait (1080×1350) gives more vertical space for full-body photos. Landscape (1080×566) suits wide scenes and group shots.
This free tool lets you resize images to Instagram's recommended sizes without uploading to any server. All processing happens in your browser. You can batch up to 10 images and download them individually or as a ZIP file.
How to resize for Instagram
Upload one or more images (JPG, PNG, or WebP, max 10 MB each). Select a preset: 1080×1080 for square, 1080×1350 for portrait, or 1080×566 for landscape. Click Resize now and download your files. The tool uses fill mode by default so your image covers the full frame — if the aspect ratio doesn't match, the edges may be cropped. For profile pictures or avatars where you want no cropping, use our Resize Image for Instagram Profile tool instead.
Frequently Asked Questions
What are the best Instagram post dimensions?
Instagram recommends 1080×1080 for square, 1080×1350 for portrait (4:5), and 1080×566 for landscape. Our presets match these exactly.
Will my images be uploaded to a server?
No. All resizing happens directly in your browser. Your images never leave your device.
Can I resize multiple images at once?
Yes, you can upload up to 10 images and resize them all with the same preset. Download individually or as a ZIP.
What if my image is smaller than 1080px?
The tool will show a warning. Upscaling can reduce quality. For best results, use a source image that's at least 1080px on the longest side.
