Image Resizer

Overview

Resize any JPG, PNG, or WebP image to a custom width and height directly in your browser using the HTML5 Canvas API. Your files never leave your device — there's no upload to a server — and you can lock the aspect ratio to avoid stretching. Ideal for preparing social media images, blog hero photos, marketplace listings, and email attachments that fit a strict size budget.

3. 3Preview the original image and double-check your target dimensions.
4. 4Click Download Resized Image to save the new file with the size in the filename.
