Frequently Asked Questions
Can I resize multiple images at once?
Yes. Upload multiple images and they will all be resized to the same dimensions. You can download all results as a zip file.
What are the best dimensions for social media images?
Common sizes include 1200x630 for Facebook and LinkedIn shares, 1080x1080 for Instagram posts, 1500x500 for Twitter headers, and 1280x720 for YouTube thumbnails. The tool includes presets for these and more.
Does resizing an image affect its quality?
Scaling an image up beyond its original resolution can cause blurriness. Scaling down generally preserves quality. For best results, start with the highest-resolution source image available.
