Image Resizer

The Image Resizer scales an image to exact pixel dimensions using the browser's Canvas API, with aspect-ratio locking switched on by default so the picture does not stretch or distort. When you genuinely need different proportions, you can unlock it to set width and height independently, then download the resized result immediately.

It suits anyone preparing images for a specific slot — profile avatars, product thumbnails, a fixed banner size or an upload limit — without opening a full graphics editor for what should be a one-step job. Setting precise dimensions in seconds is far faster than cropping and exporting in heavier desktop software, especially when you have several images to process.

Resizing is performed locally in your browser, so the image is never uploaded and stays completely private. With no install and no sign-up, you can resize a single image or work through a batch in a quick session and keep everything on your own machine.
