About this tool
The Image Resizer tool lets you change the dimensions of any photo right inside your browser without installing software. Enter a custom width and height in pixels, choose whether to keep the original aspect ratio, and download the resized image instantly. This is perfect for resizing product photos to a uniform size for an online store, preparing avatar images for social profiles that require specific dimensions, or scaling down large camera shots before attaching them to a document. The tool is completely free, works on desktop and mobile, and keeps all your image data private on your own device.

Frequently asked questions
Can I resize without distorting the image?
Yes. Enable the 'Keep aspect ratio' toggle and the tool will automatically adjust the height when you change the width.
What is the maximum output resolution?
There is no hard limit, but very large canvases (above 8000×8000 px) may be slow on older devices.
Which file formats are supported?
You can upload JPG, PNG, WebP, and GIF images. The resized output is downloaded as a PNG file.
Does resizing up (upscaling) add quality?
No. Upscaling only adds pixels through interpolation, which can make images look blurry. For best results, start with a high-resolution original.
