Image Resizer
Resize images to exact dimensions in your browser. Files never leave your device.
Runs in your browser. Nothing is uploaded.
Resize JPEG, PNG or WebP images to exact pixel dimensions or by percentage. The image is processed on your device with the browser's canvas and is never uploaded.
How it works
Choose an image, set a new width or height (the aspect ratio can be locked), pick an output format and download the result. Downscaling uses high-quality smoothing. Enlarging an image cannot add detail that was not in the original.
Examples
- Scale a 4000 × 3000 photo to 1200 × 900 for a website.
- Convert a PNG to WebP while resizing to reduce file size.
Frequently asked questions
Are my images uploaded?
No. Resizing runs entirely in your browser.
Which formats are supported?
Any format your browser can decode, typically JPEG, PNG, WebP and GIF (first frame). Output is PNG, JPEG or WebP.
Will resizing reduce quality?
Making an image smaller keeps it sharp at the new size. Making it larger will look soft because no new detail is created.
