How to Resize an Image Online
Resizing an image is useful when you need to change its dimensions for a website, blog post, social media profile, email, or another digital project. Our free image resizer lets you resize JPG, PNG, and WebP images directly in your browser.
To resize an image, upload your file using the Choose Image button or drag and drop it into the upload area. Enter the desired width and height, or use the percentage option to scale the image. Keep Lock aspect ratio enabled when you want to maintain the original proportions.
When you're ready, click Resize Image. You can preview the result and download the resized image to your device.

When Should You Resize an Image?
You may need to resize an image when its original dimensions are larger than the space where you plan to use it. For example, website owners often resize large photographs before adding them to blog posts. You might also need to change an image's dimensions for a profile picture, social media post, email attachment, presentation, or website banner.
If a website requires a particular image size, entering the required width and height into the resizer can help you create an image that matches those dimensions. For images that look stretched or distorted after resizing, enable Lock aspect ratio so the width and height remain proportional.
Does Resizing an Image Reduce File Size?
Resizing an image changes its pixel dimensions, but it does not guarantee a smaller file size. A smaller image often requires less storage than the original, but the final file size also depends on factors such as the image format, compression, image content, and quality settings. If your main goal is to reduce the file size of an image, use an image compression tool in addition to resizing when appropriate.

Does resizing an image reduce its quality?
Reducing the dimensions of an image can remove some detail because the image contains fewer pixels. The visible result depends on the original image, the new dimensions, and the output format.
