About Image Resizer
The Image Resizer changes the dimensions of a picture while keeping it sharp. People use it to shrink photos for email attachments, meet exact pixel requirements for websites and forms, create thumbnails, and enlarge images for specific layouts. Upload any common format such as JPG, PNG, or WebP, choose to resize by percentage, by exact pixel dimensions, or from a preset, and lock the aspect ratio to avoid distortion. After setting the output quality, the resized image downloads in seconds. All scaling happens in your browser, so personal photos never pass through a remote server.

Frequently Asked Questions
Are my photos uploaded to resize them?
No. The image is opened, scaled, and exported entirely inside your browser. It never touches a server, and the resized file downloads directly to your device.
Can I resize without distorting the image?
Yes. Lock the aspect ratio or use percentage scaling and the proportions stay identical to the original while the dimensions change.
Is the Image Resizer free?
Yes, completely free with no signup, no watermark, and no limit on the number of images you resize.
