Why Use a Social Media Image Resizer?
Every social media platform has its own preferred image dimensions. Sharing an image with the wrong size means it gets cropped awkwardly, stretched, or looks blurry. A social media image resizer ensures your photos, OG images, and cover photos look pixel-perfect on every platform — from Twitter cards and Facebook covers to Instagram posts and Pinterest pins.
How This Tool Works
Upload any image and select a preset size from the grid above. You can choose between Fill mode (which crops the image to perfectly fill the frame with no empty space) or Fit mode (which preserves the entire image and adds black bars if the aspect ratio does not match). The resized image is rendered using the HTML Canvas API entirely in your browser — your image never leaves your device.
Resize Images for OG Tags
Open Graph images (og:image) should be 1200 x 630 pixels for the best results across Twitter, LinkedIn, Slack, Discord, and Facebook. Use this resizer to quickly crop or fit any image to the OG standard, or generate OG images dynamically with the OGPix API.
