Free Image Resizer Online
The right dimensions for wherever it goes.
Resize an image without stretching it
Pixel dimensions describe the width and height of an image, not its file size. Keeping the original proportions makes the height follow your chosen width and prevents distortion. For a form that requires an exact width and height, turn off the proportions option, but check the preview for stretching. Enlarging a small image cannot recreate missing detail.
How to use
- Choose a JPG, PNG or WebP image.
- Set the width; keep proportions or set an independent height.
- Choose an output format, then resize. Your result downloads automatically.
A few useful answers
How do I avoid a stretched image?
Leave “Keep original proportions” selected. The height is calculated from the width and the source image’s aspect ratio.
Can I enlarge an image?
Yes, within the dimension limits, but enlarging cannot restore missing detail and may make it look softer.
Which format keeps transparency?
PNG and WebP support transparent backgrounds. JPG replaces transparency with white.
