Quick Tool Overview

The Image Resizer scales an image to exact pixel dimensions or by percentage, with the aspect ratio locked by default so nothing comes out stretched. Presets cover the sizes people ask for most, and the original dimensions are reported so you know what you started with.

About the Image Resizer

Set a target width and height in pixels, or scale by a percentage, and download the result. The aspect ratio is locked by default so images never come out stretched; unlock it when you deliberately need a fixed size such as a 1200 by 630 social preview.

Common presets are one click away — profile picture, social share card, full HD and thumbnail — and the tool reports the original dimensions so you know exactly what you started with. Resizing runs on the canvas API in your browser, so nothing is uploaded and there is no queue to wait in.

Key features of the Image Resizer

Aspect ratio locked by default

Set one dimension and the other follows, so images never come out stretched by accident.

Unlock for fixed sizes

Turn the lock off when you deliberately need an exact box such as a 1200 by 630 social card.

One-click presets

Profile picture, social share card, full HD and thumbnail are a single click away.

Pixels or percentage

Scale by a percentage when you just want it smaller, or type exact pixels when a spec demands them.

Local processing

Resizing runs on the canvas API in your browser — nothing is uploaded and there is no queue.

How to use the Image Resizer

  2. 2

    Enter new dimensions

    Type a width or height, or pick a preset. With the ratio locked, the other value follows automatically.

  3. 3

    Download the result

    Preview the resized image and save it to your device.

Frequently asked questions

No. Scaling up invents pixels from the ones already there, so the result looks softer than the original. Always resize down from the largest version you have.
