Free Online Image Resizer with Aspect Ratio Lock – No Software Needed
Resizing images for social media, websites, or email should not require Photoshop or any downloaded software. Our free image resizer works entirely in your browser — upload a photo, pick a platform preset or enter custom dimensions, and download the resized image instantly.
The aspect ratio lock ensures your image never gets stretched or distorted. Change the width and the height adjusts automatically (and vice versa). Or unlock the ratio to set exact dimensions for non-proportional resizing like YouTube thumbnails or Facebook covers.
All processing uses the HTML5 Canvas API running locally in your browser. Your images are never uploaded to any server, making this tool safe for private photos, client work, and confidential business images.

- Keep aspect ratio locked to prevent distortion, or unlock for exact dimensions.
- Choose output format (JPG, PNG, WebP) and adjust quality if needed.
