Image Resizer

An image resizer changes the pixel dimensions of your pictures. Add several images and set a maximum width and height, each one is scaled down to fit while keeping its aspect ratio, using the Canvas API. Download them individually or together as a ZIP, with no uploads involved.

How to Use the Image Resizer

  1. Select the image you want to resize.
  2. Enter the target width and/or height in pixels.
  3. Keep 'lock aspect ratio' on to avoid stretching.
  4. Preview and download the resized image.

Resizing is not the same as compressing

Resizing changes an image's pixel dimensions (its width and height), while compressing changes its file size at the same dimensions. Often you want both: a photo straight from a phone is usually far larger than a website or document needs in either sense.

Matching the dimensions to where the image will be shown avoids the browser or app having to shrink it on the fly, which keeps things sharp and fast.

Avoiding blurry or stretched results

Keep the aspect ratio locked so the image scales evenly instead of stretching. And avoid enlarging a small image beyond its original size: there is no extra detail to invent, so it will look soft or blocky.

Start from the highest-quality original you have, resize down to the target, and you will get a crisp result. Everything runs in your browser, so the image never leaves your device.

Frequently Asked Questions

Will resizing distort my image?

Not if you keep the aspect-ratio lock enabled, the width and height scale together. Turning it off lets you set exact dimensions but can stretch the picture.

Can I enlarge a small image?

Yes, but enlarging beyond the original resolution can look soft or pixelated because the tool has no extra detail to add.

Is my image private?

Yes. Resizing runs on the Canvas API in your browser, so the image never leaves your device.
