Resizing an image to specific pixel dimensions — for an avatar, a thumbnail, an upload limit — usually means opening a heavy editor or an online service that uploads your photo. This free Image Resizer scales any JPG, PNG or WebP right in your browser using the Canvas API, with optional aspect-ratio locking and a choice of output format, then lets you download the result. Your image never leaves your device.
How to use it
- Drop or select an image.
- Set the target width (and height), and pick an output format.
- Download the resized image.
Why use this tool
- Pixel-precise resizing with aspect-ratio lock.
- PNG, JPEG or WebP output.
- Runs in your browser — nothing is uploaded.
