Resize Image FAQ

Quick answers about formats, quality, aspect ratio, and browser-based resizing.

Is the Resize Image tool free to use?

Yes. You can upload an image, change its width and height, preview the result, and download the resized file for free.

Can I resize JPG, PNG, and WebP images?

Yes. The tool accepts PNG, JPG, WebP, GIF, and AVIF images. TIFF and SVG files are not supported. Downloads are PNG files, and animated inputs are flattened to one still frame.

Will resizing reduce image quality?

Reducing dimensions can make an image smaller, while enlarging may reduce sharpness depending on the original image resolution. The resized PNG uses high-quality browser image smoothing.

Can I keep the original aspect ratio?

Yes. Turn on Maintain Aspect Ratio to automatically update height when width changes, or width when height changes.

How are resized files stored?

Resizing happens entirely in your browser. Images are never uploaded to a server, so nothing is stored remotely and files are discarded when you leave the page.
