Social Media Image Resizer

Both. The tool scales your image to fill the target dimensions (like 'cover' mode in CSS), then center-crops any excess. This ensures the output is exactly the required pixel size with no black bars.

No. All processing happens in your browser using the Canvas API. Your image never leaves your device.

Instagram feed posts: 1080x1080 (square), 1080x1350 (portrait), or 1080x566 (landscape). Instagram Stories and Reels: 1080x1920. This tool uses 1080x1080 for the square post format.

The resized image is saved as PNG to preserve full quality. For web uploads, PNG works with all social media platforms.
