Will resizing make my image blurry?

Downscaling uses the browser's high-quality smoothing and stays sharp. Upscaling beyond ~200% will soften details, like with any resampling method.

Resize Images to Exact Pixel Dimensions — Locally in Your Browser

Set an exact width and height in pixels or scale by percentage. The aspect-ratio lock keeps proportions correct: type a new width and the height is calculated automatically. Multiple images can be resized with one setting and downloaded together as a ZIP.

Because the resizing happens with your browser's native canvas, there is no upload wait and no server processing — resizing a 12-megapixel photo takes milliseconds.

Frequently Asked Questions

Everything you need to know about using Image Resizer safely and efficiently.

Yes. With the lock on, entering a width automatically calculates the proportional height (and vice versa). Turn it off for free-form, exact-pixel crops-to-canvas.
