Image Resizer

Resize images online for free

Drop or select any image and set your target width, height, or both. Enable “keep aspect ratio” to avoid distortion — the tool computes the missing dimension automatically. The resize happens on a canvas element inside your browser; your file never leaves your device.

Supports JPEG, PNG, WebP, and any other format your browser can decode. The download button saves the resized image as a PNG.

FAQ

Is my image uploaded to a server? No — everything runs in your browser using the Canvas API. Your image stays on your device.
