Resize Image changes the width and height of a picture in pixels. Lock the aspect ratio to avoid stretching, or use presets such as a 1080×1920 story or 1920×1080 HD. You can also change the output format and quality at the same time. The preview updates live, and the image is processed entirely on your device.
Open Resize Image
Launch Resize Image directly in your browser — there is nothing to download, install, or configure first.
Add your image
Drag and drop or select the image (or images) you want to work with. They load straight into Resize Image and are never uploaded.
Adjust and apply
Fine-tune the available settings and run Resize Image. Your images are processed entirely in the browser.
Keep “maintain aspect ratio” on. Change the width and the height follows automatically.

Smaller dimensions almost always mean a smaller file. Lowering the quality setting shrinks it further.
Yes. Resize Image is completely free, with no account, no paywall, and no usage limits.
No. Resize Image works instantly in any modern web browser — there is no software to install, no extension, and no sign-up.
