Open Image Resizer →Frequently asked questions
What is the best image format for social media?
Use JPG for photos (smallest file size), PNG for graphics with text or transparency, and WebP when the platform supports it (Facebook, LinkedIn). Avoid GIF for photos - use MP4 or JPG instead.
What size should Instagram posts be?
Instagram recommends 1080 x 1080 pixels for square posts, 1080 x 1350 for portrait posts, and 1080 x 566 for landscape posts. Stories are 1080 x 1920.
What size should Facebook cover photos be?
Facebook recommends 820 x 312 pixels for page cover photos, but we recommend uploading at 1640 x 624 for retina displays. The safe area for text is 640 x 312.
Does compressing images for social media reduce quality?
At quality 80-85%, compression is invisible to the human eye. Social media platforms also compress your images automatically when you upload them, so pre-compressing actually gives you more control over the final result.
What is the ideal Twitter/X image size?
For in-stream images: 1600 x 900 pixels (16:9 ratio). For profile photos: 400 x 400. For header images: 1500 x 500. Keep in mind that Twitter crops images in the timeline based on aspect ratio.
