A photo straight from a phone camera is often far larger than any web page, social post, or thumbnail actually needs, and that mismatch slows pages down for no visual benefit. Set an exact width and height, a percentage, or a maximum width, and the image resizes to fit — all inside the browser.

What this tool does

The image is scaled on a canvas to the width and height you specify — or to a percentage or maximum width — and then exported in the format you selected, without ever leaving your device.

How to use it

Upload an image.
Enter a width and height, a percentage, or a maximum width.
Process the file and download the result.

What you get

An aspect-ratio lock keeps proportions correct automatically.
Percentage-based scaling for quick resizing.
An optional max-width constraint for responsive layouts.

Typical uses

Creating a 1200px-wide header image for a blog post.
Downscaling phone photos to fit an upload limit.
Generating consistent product thumbnails for a catalog.

Examples

A 4000×3000 photo resizes to 1200×900 with the aspect ratio locked.
A 50% scale produces a quick half-size export of the same image.

Worth knowing

Upscaling a small image won't add detail that wasn't there to begin with.
Unlocking the aspect ratio can stretch or squash the image unintentionally.

Frequently asked

Can I upscale safely?

You can enlarge an image, but its quality won't exceed what the original source already contained.

Are files uploaded?

No. All resizing happens locally in your browser.
