How to Resize an Image Online
Whether you are scaling an image down to save space or resizing a graphic to meet specific upload requirements, our client-side image resizer provides perfect pixel control without sacrificing quality.
- Upload your image: Drag and drop your image file, browse your device, or paste a copied image directly into the workspace.
- Choose your mode: In the right panel, select whether you want to resize your image by exact pixels or by a percentage of its original size.
- Enter your dimensions: Type your new width or height. By default, the aspect ratio is locked (the chainlink icon is highlighted), meaning if you change the width, the height will automatically calculate to prevent your image from stretching.
- Review the Live Preview: The central canvas provides an accurate, real-time preview of your scaled image. Use your mouse wheel to zoom in and check the details.
- Download: Click "Instant Download" to save the resized image as a high-quality PNG to your device.
Frequently Asked Questions
Are my images uploaded to your servers?
No. All resizing happens entirely inside your web browser. Your original files and the resized outputs never leave your device, ensuring total privacy.
Will making an image larger reduce its quality?
Yes, upscaling (making an image larger than its original dimensions) generally reduces visual sharpness. Because standard resizing uses pixel interpolation—rather than AI generation—to fill in the missing data, upscaled images may appear blurry or pixelated.
How do I resize an image without distorting it?
To prevent your image from stretching or squishing, ensure the "Constrain Proportions" lock icon is highlighted in the right panel. This guarantees that any changes you make to the width will proportionally affect the height, maintaining the original aspect ratio.
