image resizer

Resize any image to exact pixel dimensions with optional aspect ratio locking for perfect proportions.

Image Resizer gives you precise control over the dimensions of your photos and graphics. Upload any image, set your desired width and height, and download the resized version instantly. The maintain aspect ratio option ensures your images never appear stretched or distorted when you change one dimension — the other adjusts automatically to preserve the original proportions.

This tool is essential for social media managers who need images at specific sizes for different platforms, developers building responsive layouts, and anyone preparing graphics for presentations, documents, or print materials. Instead of opening heavyweight image editors, you can resize in seconds directly from your browser.

The resizer supports all common image formats including JPG, PNG, WebP, and GIF. It preserves the original format during export — PNG files remain PNG with transparency intact, JPG files stay as optimized JPEGs, and WebP files maintain their modern format. Original dimensions are displayed for reference so you always know your starting point.

All processing happens entirely in your browser using the Canvas API. No images are uploaded to any server, ensuring complete privacy for sensitive or proprietary visuals. Upload, set your target dimensions, and download — it's that simple.
