What is the Image Resizer?

Resize any image to exact pixel dimensions, keep its proportions or stretch it, and save it as PNG, JPG or WebP. Useful for profile pictures, forms with size limits and web images.

How it works

How to use the Image Resizer

3 simple steps. No experience needed.

What can you use it for?

  • Resize a photo to the size a website or form asks for.
  • Make a large image smaller for the web.
  • Create a thumbnail version of an image.

Keeping proportions

With proportions locked, changing the width updates the height automatically so the image isn't squashed. Unlock it only when a form demands exact dimensions — the picture will stretch to fit.

Choosing a format

The resizer keeps your original format by default. Save as JPG or WebP for photos you want small, or PNG for screenshots, logos and anything with transparency.

FAQ

Frequently asked questions

Will making an image bigger improve its quality?

No. Enlarging adds pixels by estimating them, so the image looks softer. Start from the largest version you have.

What's the maximum size?

Up to 12,000 pixels on each side, depending on your device's memory.

How do I resize an image for a profile picture?

Crop it to a square with the image cropper first, then resize it here to the size the site asks for — 400 × 400 px is a common choice.
