Image Resizer
Scale an image to exact pixel dimensions or a percentage of its original size — with the aspect ratio kept intact automatically.
How to resize an image
- Add your imageDrag & drop it, browse for it, or paste it from your clipboard.
- Pick a sizeScale by percentage, or switch to “By dimensions” and enter an exact width and height. The ratio lock keeps things from stretching.
- Resize & downloadCheck the live preview, choose an output format if you like, and download the result.
Why resize images?
Phone cameras produce 4000-pixel-wide photos — far larger than any website, email or form actually needs. Scaling an image down to 1600 px wide for a blog post, or 800 px for a listing, cuts its file size enormously and makes pages load faster.
Common uses: fitting profile pictures to exact squares, meeting upload limits like “max 1200 px”, preparing screenshots for documentation, and shrinking photos for email. Combine resizing with the compressor for the smallest possible file.
FAQ
How do I keep the image from stretching?
Leave “lock ratio” checked (it is by default). When you change the width, the height adjusts automatically to match the original proportions, and vice versa.
Can I enlarge a small image?
Technically yes, but enlarging stretches the existing pixels and makes the result soft or blurry. If you need a bigger image, it is better to find a higher-resolution original.
Which output format should I choose?
“Same as original” is the safe default. Pick JPEG for photos (smaller), PNG for screenshots and graphics that need sharp edges or transparency, and WebP for the best overall compression on the web.
Are my images uploaded anywhere?
No. The resizing runs entirely in your browser with JavaScript — nothing is sent to any server.
