Social Media Image Resizer

What is the Social Media Image Resizer?

This tool lets you take a single image and instantly resize it for every major social media platform. Instead of manually creating separate files in Canva or Photoshop, select the platforms you need, choose a fit mode, and download everything in one click. All processing happens in your browser — your images stay private and are never uploaded.

How to Use

1. Upload an image by clicking the drop zone or dragging a file onto it.
2. Select the social media sizes you need from the grid. Use "Select All" for a full set.
3. Choose a fit mode: Fill (crops to fit), Fit (pads with background), or Stretch.
4. If using Fit mode, pick a background color for the padding area.
5. Click Generate All Sizes to create your images.
6. Preview each result, download individually, or click Download All as ZIP.

Tips

• Start with the highest resolution source image you have for the best quality across all sizes.
• Fill mode works best when your subject is centred — edges may be cropped.
• Fit mode preserves the entire image; use a brand-coloured background for a polished look.
• Download the ZIP to quickly batch-upload to scheduling tools like Buffer or Hootsuite.
