How to Resize an Image to Exact Pixel Dimensions

Sometimes you need a photo at a precise size — 1080×1080 for a post, 600px wide for a website, a specific pixel size for a form. Here’s how to resize exactly, keep it sharp, and avoid the stretched look.

Step by step

  1. Open the image tool and add your photo (drag it in or tap to choose).
  2. Enter the width and height in pixels you need.
  3. Keep the aspect ratio locked unless you truly need to stretch — this prevents distortion.
  4. Download the resized image. It’s processed on your device, so nothing is uploaded.

The one rule that keeps images sharp

Resizing down (making an image smaller) almost always looks fine. Resizing up (making a small image bigger) does not — the browser has to invent pixels that were never captured, so the result looks soft or blocky. Whenever you can, start from the largest original you have and scale down to the size you need.

💡 Keep the proportions: if the original is 4000×3000 (a 4:3 shape) and you force it into 1000×1000 (a square), everything looks squashed. Either keep the ratio (e.g. 1000×750) or crop to a square first, then resize.

Resize vs crop — which do you need?

Common target sizes

If a form also caps the file size (like 50KB), resize to the required pixels first, then compress it under the limit.

FAQ

Will resizing lower the quality?
Resizing down keeps quality well. Resizing up reduces sharpness because pixels have to be invented.

How do I resize without stretching?
Keep the aspect ratio locked, or crop to the shape you want before resizing.

Is my photo uploaded?
No. The resizing happens in your browser, so your image never leaves your device.

Which format should I save as?
JPG for photos, PNG when you need transparency, WebP for the smallest file at good quality.
