Image Resizer
Resize images to exact pixel dimensions or by percentage. Keep the aspect ratio locked, choose JPG, PNG or WebP output, and download locally.
How to use
- 1
Upload an image with drag and drop or the file picker.
- 2
Choose a preset, or type your own width and height.
- 3
Keep "Maintain aspect ratio" on so the other edge is computed for you.
- 4
Pick an output format and click Download.
How it works
The browser draws your source image onto a canvas sized to the target dimensions, then reads it back as JPG, PNG or WebP. Everything happens locally; no intermediate server round-trip is involved.
Frequently asked questions
Will resizing reduce file size?
Usually yes - fewer pixels means less data. You can pair this tool with the Image Compressor for maximum savings.
What if I turn off the aspect ratio lock?
The image is stretched to the exact dimensions you enter. Keep the lock on unless you deliberately want distortion.
Which output format should I pick?
PNG for images that need transparency, JPEG for photos, WebP for the best size-to-quality ratio on modern browsers.
