Resize images to the exact dimensions every social platform requires. Pick a platform, enter the size, and download — your image never leaves your browser.
Upload your image to ImageResizer Studio, select the target platform dimensions from the table below, and click resize. For Instagram, use 1080×1080 for feed posts, 1080×1350 for portraits, and 1080×1920 for stories. For Facebook, use 820×312 for covers and 1200×630 for link shares. All processing happens in your browser — your image is never uploaded to a server. Free, no account required.
Every platform has its own recommended image dimensions. Here is a complete reference for the most popular social networks.
Use 1080 × 1080 pixels for square posts, 1080 × 1350 for portrait posts, or 1080 × 1920 for stories. Instagram compresses images, so uploading at these exact sizes minimizes quality loss.
Facebook cover photos display at 820 × 312 pixels on desktop. Upload at 820 × 312 or larger (Facebook will scale it). The tool maintains your aspect ratio while resizing.
For image tweets, use 1200 × 675 pixels (16:9 ratio). For header images, use 1500 × 500 pixels. Twitter compresses images, so these sizes give the best quality-to-file-size ratio.
Yes. Use the bulk image resizer to upload up to 50 images and apply the same dimensions to all of them. This is ideal for preparing a batch of social media posts.
Yes, all platforms compress images. Uploading at the recommended dimensions minimizes additional compression. JPEG at quality 85 is ideal for social media — small enough to upload fast, large enough to look sharp.
