How to Resize Images to Exact Pixels

Whether you need a specific dimension for a website upload or you want to perfectly fit a social media header, our Free Image Resizer makes it incredibly simple.

  1. Upload an Image: Drag and drop your image into the box.
  2. Choose Dimensions: Either type your exact desired Width and Height in pixels, use our Quick Resize percentages (25%, 50%, etc.), or click one of the Social Media Presets.
  3. Lock Aspect Ratio: Click the padlock icon to maintain the original proportions of your image and prevent stretching.
  4. Resize & Download: Click "Resize Image" and then download your new perfectly-sized image.

Frequently Asked Questions

Will resizing my image reduce its quality?

Making an image smaller (downsizing) generally keeps the image looking crisp and sharp. However, making an image significantly larger (upscaling) than its original size may cause it to look blurry or pixelated because the browser has to invent new pixels.

Why is my resized image stretched?

If your image looks stretched or squished, it means you changed the dimensions without locking the aspect ratio. Click the "padlock" icon to lock the aspect ratio, and the tool will automatically calculate the correct height when you type a width!
