Image Resizer Online

Prepare images for websites, profile pictures, presentations, forms and social media by setting the exact dimensions you need. Enter a target width and height in pixels, and keep the aspect-ratio option enabled to avoid stretching the image. Export your resized image as PNG, JPG or WebP.

How to use the Image Resizer

  1. Select the image you want to resize.
  2. Enter the new width and height in pixels. Keep the aspect-ratio option enabled for proportional resizing.
  3. Choose an output format, process the image and download the resized file.

About this image tool

The resizer uses your browser canvas to create a new image at the requested dimensions. When aspect ratio is enabled, changing one dimension updates the other using the original image proportions. A larger output canvas does not restore detail that was not present in the source. For best results, avoid enlarging a small image too aggressively and keep an unedited copy of the original file.

Frequently asked questions

Can I resize an image without stretching it?

Yes. Keep the aspect-ratio option selected. The other dimension is calculated from the original proportions.

Does resizing improve image quality?

No. Resizing changes pixel dimensions; it cannot recreate missing detail. Enlarging a small image can make it look soft or pixelated.

Which dimensions should I use?

Use the exact pixel dimensions required by the destination platform or design. There is no single size that fits every website or social network.
