Social Media Image Resizer
Resize your images to the perfect dimensions for every social media platform. The Social Media Image Resizer comes with built-in presets for Instagram, Twitter/X, YouTube, Facebook, and LinkedIn so you never have to look up the right size again. Choose between cropping and letterboxing to control how your image fits each format.
Features
- Platform presets for Instagram (post, story, reel), Twitter/X (header, post), YouTube (thumbnail, banner), Facebook (cover, post), and LinkedIn (banner, post)
- Crop mode that fills the target dimensions by trimming edges, keeping the focus on the center of your image
- Letterbox mode that fits your entire image within the target size, adding bars to fill the remaining space
- Custom dimensions if you need a size that is not covered by the built-in presets
- Instant preview so you can see the result before downloading
- Client-side processing that keeps your images private and never uploads them to a server

FAQ
What is the difference between crop and letterbox?
Crop fills the entire target area by trimming parts of your image that fall outside the frame. Letterbox scales your image to fit entirely within the frame and adds colored bars (usually black or white) to fill the remaining space. Use crop when you want edge-to-edge coverage and letterbox when you need to keep the full image visible.
Are my images uploaded to a server?
No. All resizing happens directly in your browser. Your images stay on your device and are never sent to any external server.
Can I resize for a platform that is not listed?
Yes. You can enter custom width and height values to resize your image to any dimensions you need.
