Free Image Resizer Online
Need to resize an image online for a website, email, social media post, online form, marketplace listing, or document? ToolsPoint Online provides a free browser-based image resizer that lets you change image dimensions by entering exact pixel values.
You can resize JPG, resize PNG, and resize WebP images without installing desktop software. Upload an image, set the target width or height, keep Lock Aspect Ratio enabled when you want proportional resizing, choose JPEG, PNG, or WebP output, and download the resized file.
This page is designed around common US and UK search intents such as image resizer online, resize image online free, photo resizer, resize JPG image, resize PNG image, and resize WebP image. It also supports practical long-tail needs such as changing an image to a specific width and height in pixels while avoiding unnecessary distortion.
If you need a particular file size rather than specific dimensions, use an image compressor after resizing. For example, resizing a large photo first can make later compression more efficient. The exact visual result depends on the original image, target dimensions, format, and browser rendering.
Image processing takes place in your browser using standard web technologies. Files are not intentionally uploaded to a ToolsPoint Online server by this tool. For confidential or regulated material, always follow your own privacy and security requirements.
How to Resize an Image
- Upload a JPG, PNG, or WebP image using the file picker or drag and drop it into the upload area.
- Enter the target width or height in pixels.
- Keep Lock Aspect Ratio enabled when you want the image proportions preserved.
- Select JPEG, PNG, or WebP as the output format.
- Click Download Resized Image to save the result.
Resize Images by Exact Pixels
Exact pixel resizing is useful when a website, application, form, profile, thumbnail, or marketplace requires a particular image dimension. Enter the required width and height to create an image that matches those specifications. If the aspect ratio is locked, changing one dimension automatically calculates the other.
Keep the Image Aspect Ratio
Changing width and height independently can stretch or squash a photo. Keeping the aspect ratio locked is usually useful when you want a proportional image resize. If a design specifically requires a fixed width and height, you can unlock the ratio and set both dimensions manually, but the source image may become distorted.
JPG, PNG and WebP Image Resizing
JPG is commonly used for photographs, PNG works well for graphics and images where lossless output or transparency matters, and WebP is a modern format often used for web images. You can choose the output format after setting your target dimensions.
Image Resizing for Websites and Social Media
Resizing a large image before publishing can make files easier to manage and can help avoid oversized dimensions. Always check the requirements of the destination platform because recommended image dimensions can change over time. This tool changes pixel dimensions; it does not guarantee that a resized image will meet a particular platform's current upload or file-size limits.
Frequently Asked Questions
Is this image resizer free?
Yes. The core image resizing tool is free to use and does not require an account.
Can I resize an image to a specific width and height?
Yes. Enter the required width and height in pixels. Lock Aspect Ratio can be enabled for proportional resizing or disabled when you intentionally need independent dimensions.
Will resizing reduce image quality?
Reducing dimensions generally keeps a clear result, while enlarging an image beyond its original dimensions can make details look softer. The final quality also depends on the selected output format.
Are my images uploaded to a server?
The resize operation is performed in your browser and the selected image is not intentionally uploaded to a ToolsPoint Online server.

After resizing, you can compress an image to reduce its file size, crop it for a specific composition, rotate it, or inspect basic image information with the related tools below.
Choose the Right Image Dimensions
For a clean resize, start with the dimensions required by the destination. Keep the aspect ratio locked for normal photos, and use a specific width and height only when the destination requires fixed dimensions. If the resulting file is still too large, use the Image Compressor to reduce file size after resizing.
