What Is an Image Resizer?
An image resizer is an online tool that changes the dimensions of an image while keeping it in a usable digital format. You can change the width and height of a photo in pixels without needing professional photo editing software.
Our free image resizer supports popular formats including JPG, JPEG, PNG and WebP. You can enter custom dimensions, keep the original aspect ratio, select an output format and download the resized image immediately.
Image resizing is different from simply changing the file name or reducing the file size. When an image is resized, its pixel dimensions are changed. For example, a 4000 × 3000 image can be resized to 1200 × 900 pixels.
Why Should You Resize Images?
Large images are often unnecessary for websites, online forms, social media posts and documents. Resizing an image can make its dimensions more suitable for the platform where you want to use it.
Better Website Performance
Smaller image dimensions can reduce the amount of visual data a browser needs to process. Properly sized images can therefore be useful as part of an overall website performance and image optimization strategy.
Easier Online Uploads
Some websites, job portals, application forms and online services require images with specific dimensions. A free online image resizer lets you prepare an image before uploading it.
Social Media Images
Social media platforms often display images according to specific layouts and aspect ratios. Resizing your photo can help you prepare it for profile pictures, posts, thumbnails and other digital content.
Website Images
Website owners can resize oversized photos before adding them to pages, blog posts, product listings or other website content. Correct image dimensions can also complement other SEO and performance optimization techniques.

Frequently Asked Questions
What is the best free image resizer online?
A useful image resizer should provide custom dimensions, support common formats, maintain aspect ratio when needed, work quickly and make the resized file easy to download. This tool provides these features directly in your browser.
Can I resize JPG images online?
Yes. You can select JPG or JPEG images, enter your desired dimensions and download the resized image.
Can I resize PNG images?
Yes. PNG images are supported. If you select PNG as the output format, the resized image can retain PNG transparency where supported by the source image and browser.
Can I resize WebP images?
Yes. WebP is supported as an input and output format in modern browsers.
Will resizing stretch my image?
Not when Lock Ratio is enabled. The tool calculates the second dimension from the original image proportions. You can unlock the ratio if you specifically need custom width and height values.
Can I resize multiple images at once?
Yes. You can select multiple supported images or drag and drop multiple files into the upload area.
Does the image resizer upload my photos?
The resizing process runs inside your browser. The images are not intentionally uploaded to the website's server for processing.
What is the difference between resizing and compressing an image?
Resizing changes the pixel dimensions of an image, such as changing 3000 × 2000 pixels to 1200 × 800 pixels. Compression primarily reduces the amount of data stored in the image file. Both techniques can be used together when optimizing images.
Conclusion
A properly sized image is easier to use across websites, online forms, social media platforms, documents and digital projects. Instead of installing complicated image editing software, you can use a free online image resizer to quickly change image dimensions.
With this Image Resizer, you can resize JPG, JPEG, PNG and WebP images, choose custom width and height values, maintain the original aspect ratio and download the finished image directly to your device.
For best results, choose dimensions that match the actual place where your image will be displayed. If you also need to reduce the file size in KB or MB, use an image compression or image size reduction tool in addition to resizing.
Need to Reduce Image File Size Too?
If your image needs to be reduced to a specific KB or MB target, use an image size reducer/compressor in addition to resizing.
