What it 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
- Upload an image.
- Enter a width and height, a percentage, or a maximum width.
- Process the file and download the result.
Features
- An aspect-ratio lock keeps proportions correct automatically.
- Percentage-based scaling for quick resizing.
- An optional max-width constraint for responsive layouts.
Use cases
- 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.
Common mistakes
- 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.
FAQ
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.
