About Social Media Image Resizer
Prepare images for common social publishing layouts without guessing the pixel dimensions each time. Choose presets for square posts, portrait posts, vertical stories, YouTube thumbnails or wider social graphics. Upload a JPG, PNG or WebP image and select Cover to fill the frame with a centered crop, or Contain to keep the entire picture inside the new dimensions with padding where needed. Cover works well for photography when edge cropping is acceptable; Contain is safer for diagrams, product images and graphics containing important text near the edges. Review the preview for cropped faces, logos and captions before exporting. These are common preset sizes rather than a guarantee that every social platform will always use them; check current platform specifications before publishing. Image processing takes place locally in your browser.
