About the Image Resizer
The Image Resizer changes the dimensions of an image to exact pixel values or by percentage, with a live preview. Resizing is essential for meeting platform requirements — avatars, banners, product photos — reducing file size for faster pages, and preparing images for print or documents.
The tool preserves aspect ratio by default so photos never look stretched, and everything runs locally in your browser: your images are never uploaded.
How to use it
- Upload or drag your image into the tool.
- Enter the target width or height in pixels, or choose a percentage.
- Keep aspect ratio locked to avoid distortion, or unlock it for exact dimensions.
- Preview and download the resized image.
Frequently asked questions
Will enlarging an image improve its quality?
No — upscaling cannot add detail that was not captured. It is best for slight enlargements; shrinking always preserves sharpness.
What does "keep aspect ratio" do?
It scales width and height together so the image is never stretched or squashed. Unlock it only when a platform demands exact dimensions.
What formats are supported?
PNG, JPEG, WebP, and other common formats.
Are my photos private?
Yes. Resizing happens on your device; images never leave your browser.
