Free Image Resizer for JPG, PNG and WebP
OnlineFreeTools provides a free online image resizer for quickly changing the dimensions of digital images. You can resize an image by entering a specific width and height in pixels while optionally maintaining its original aspect ratio.
The image resizer works directly in a modern web browser. This means you can select an image from your computer, phone, or tablet, adjust its dimensions, choose an output format, and download the processed image without sending the original file to a remote image-processing server.
Resize Images Without Losing Their Proportions
Maintaining the correct aspect ratio helps prevent images from appearing stretched or compressed. Enable the “Maintain aspect ratio” option and changing the width will automatically calculate the corresponding height, or vice versa.
Convert While Resizing
The tool can export resized images as JPEG, PNG, or WebP. This makes it useful when you need to prepare an image for a website, social media profile, email, document, presentation, or other digital project.
Browser-Based Image Processing
Image processing is performed using your browser's built-in image and canvas capabilities. Because the resizing process runs locally, you do not need to wait for an image to be uploaded to a server before it can be processed.
Common Uses for an Image Resizer
- Resize large photos for websites.
- Create images with specific pixel dimensions.
- Prepare pictures for online forms and profiles.
- Resize images for documents and presentations.

Frequently Asked Questions
Is this image resizer free?
Yes. The OnlineFreeTools image resizer is available to use directly in your browser without requiring a paid image-editing application.
Are my images uploaded to a server?
The resizing process is performed locally in your browser. The image selected for resizing is not uploaded to the OnlineFreeTools server for processing.
Can I maintain the original aspect ratio?
Yes. Enable “Maintain aspect ratio” and the tool automatically calculates the corresponding dimension when you change the width or height.
Which image formats can I export?
You can export the resized image as JPEG, PNG, or WebP.
Can I resize an image to an exact pixel size?
Yes. Enter the required width and height in pixels. If maintaining the aspect ratio is enabled, the second dimension will be calculated automatically.
Does resizing an image reduce its quality?
Changing image dimensions can affect image quality. Reducing dimensions generally removes pixel information, while enlarging an image requires the browser to interpolate additional pixels. The result depends on the original image, target dimensions, and selected output format.
