Image Resizer - Free Online Image Resizer in Your Browser

Resize any image to exact dimensions — aspect ratio lock, quick-size presets, and PNG, JPEG, or WEBP output. Everything runs in your browser; your images never leave your device. This free online image resizer processes files locally using the HTML Canvas API, so there is no upload and no server.

How to Use

1. Upload or drag & drop your image (PNG, JPEG, WEBP, GIF, BMP, SVG — any format your browser can decode).

2. Set the target size — type exact width and height, toggle the aspect-ratio lock, or pick a quick preset like Instagram Post, YouTube Thumb, or Favicon 32×32.

3. Choose the output format — PNG, JPEG, or WEBP. For JPEG/WEBP you can also dial the quality.

4. Resize — the tool renders the new image to a canvas and shows a live preview with the resulting pixels and scale percentage.

5. Download the resized file, or Copy the result.

Example

Load a 4000×2670 photo, set the target to 1280×720 (the YouTube Thumb preset), pick WEBP at 85% quality, and hit Resize. The preview shows a 1280×720 webp; Download saves it as -resized-1280x720.webp.
