About Image Resizer
Resize images to exact pixel dimensions online for free, right in your browser. Whether you need a photo at a specific width for a website, a profile picture cropped to size, or an image scaled down to meet an upload limit, this tool does it in seconds. Lock the aspect ratio to keep proportions perfect, or unlock it to set a custom width and height. Because the resizing happens locally using the HTML canvas, your photos are never uploaded to any server - they stay private on your device - and there's no signup, watermark, or limit on how many images you resize.
How to use this tool
- 1Upload an image (JPG, PNG, or WebP).
- 2Enter the target width or height; the other side follows the aspect ratio unless unlocked.
- 3Click Resize and download the result.
Frequently asked questions
Will resizing reduce image quality?
Shrinking an image keeps it sharp. Enlarging beyond the original size can look soft because pixels must be interpolated.
Are my photos uploaded to a server?
No. Resizing happens entirely in your browser using the canvas API; files never leave your device.
