Image Resizer - Resize, compress, and enhance your images in seconds FREE

Free online image resizer & compressor

Image Resizer is a free tool that resizes, compresses, converts, and enhances your photos directly in your browser. Because everything runs on your own device with the HTML Canvas API, your files are never uploaded to a server — which makes it safe for private, confidential, or client-owned images. There is no signup, no watermark, and no cost.

How to resize an image

1. Upload. Drag and drop up to 10 images, or click to browse your device.
2. Choose a size. Pick a social media preset or enter custom width and height, then choose a fit mode.
3. Set quality and format. Export as JPG, PNG, WebP, or AVIF, or turn on web optimization to target files under 1MB.
4. Download. Save each optimized image, or grab the whole batch as a single ZIP.
