About Resize image

Set a width, a height, or both, or scale by percent, and resize one image or a whole batch. The aspect ratio is locked by default so nothing looks squashed, and resampling keeps edges clean.

  • Resizing down is always safe; enlarging adds pixels and can look soft.
  • Common sizes: 1920 px wide for web headers, 1080 px for Instagram, 400 px for thumbnails.
  • Use Social media resizer to get every platform size from one upload.

How to use it

  1. 1Drop your images.
  2. 2Enter the target width or height, or a percentage, and choose the format.
  3. 3Download the resized files.

Questions

Does resizing reduce file size?
Yes, usually a lot. Halving the width cuts the pixel count by four.
Can I resize to a fixed box?
Enter both width and height and choose whether to fit inside the box or crop to fill it.
Are images uploaded?
No. Everything runs in your browser, so your photos never leave your device.
