How to Resize Images for Web Uploads and Social Media

Websites, marketplaces, and social platforms often require specific image dimensions. Uploading the wrong size results in awkward cropping, stretched images, or outright rejection.

How to Resize

  1. Open Image Resize.
  2. Upload your image (JPG, PNG, or WebP).
  3. Enter the target width and height.
  4. Enable "Lock aspect ratio" if you want proportional scaling.
  5. Choose output format if needed.
  6. Download the resized image.

Resize by Percentage

If you just need to make an image smaller without a specific pixel target:

  • 50% reduces the image to half its dimensions
  • 25% creates a thumbnail-sized version

After Resizing

  • If the file is still too large, use Image Compress to reduce the file size.
  • If you need a different format (e.g., PNG to JPG), use Image Converter.

Quality Tips

  • Enlarging a small image (e.g., 300px to 1200px) will look blurry. Always start with the largest source image available.
  • For web use, JPG at 80–85% quality offers the best balance of size and appearance.
  • Resize first, then compress. This order gives better results than compressing first.
