About This Tool

The Social Media Image Resizer gives you a single reference for every major platform's recommended image sizes in 2026, plus a built-in resizer that crops, letterboxes, or stretches your image to exact specifications — entirely in your browser. In Crop mode, drag to reposition exactly which part of your image appears in the final output.

Platform Dimensions FAQ

Why do image sizes vary by platform? Each platform has different display sizes, compression algorithms, and aspect ratio requirements. Using the correct dimensions prevents automatic cropping or quality loss.

What is "letterbox" mode? Letterbox adds padding (black bars or transparent) around your image to fill the target canvas without cropping. Use this when you can't afford to lose any part of the image.

Which format should I choose? Use JPG for photos (smaller file size), PNG for graphics or images with transparency, and WebP for the best quality/size ratio on modern platforms.

Is my image uploaded anywhere? No. All processing happens locally in your browser using the Canvas API. Nothing leaves your device.
