Image Resizer
Resize an image by specifying new width and height. Works completely in your browser.
What is Image Resizing?
Image resizing is the process of changing the dimensions (width and height in pixels) of an image. This is commonly needed when preparing images for social media platforms that require specific dimensions, optimizing images for website use to reduce loading times, or fitting images into presentations and documents. Maintaining the correct aspect ratio during resizing prevents the image from appearing stretched or distorted.
How to Use
- Select an image file (JPG, PNG, or WebP) using the file picker above.
- The tool will display the original dimensions. Enter your desired width and height in pixels.
- Keep the "Keep aspect ratio" checkbox enabled to prevent distortion. Changing one dimension will automatically adjust the other.
- Click "Resize image" to generate the resized version, then download it.
Frequently Asked Questions
What is aspect ratio and why does it matter?
Aspect ratio is the proportional relationship between an image's width and height. Maintaining the aspect ratio when resizing ensures the image does not appear stretched or squished. For example, a 1920x1080 image has a 16:9 aspect ratio.
Will resizing reduce image quality?
Reducing the size of an image generally preserves quality well. However, enlarging an image beyond its original dimensions can result in pixelation and blurriness because the tool has to create new pixel data that did not exist in the original.
Is my image uploaded to a server?
No. All resizing happens entirely in your browser using the HTML5 Canvas API. Your image never leaves your device, ensuring complete privacy.
