How can I resize an image online for free?

To resize an image online free, upload your image, enter the desired width and height (or choose a preset), and click 'Resize Image'. Your resized image downloads instantly. All processing happens locally in your browser with no uploads, no watermarks, and unlimited resizes.

Can I maintain the aspect ratio when resizing?

Yes. By default, aspect ratio is locked. When you change the width, the height adjusts automatically (and vice versa). You can unlock it to set custom dimensions.

What image formats are supported?

The image resizer supports JPG/JPEG, PNG, WebP, and GIF formats.

Is this image resizer secure and safe?

Yes. When you resize images with our online image resizer, all processing happens locally in your browser. Your images are never uploaded to our servers or stored anywhere, making it completely secure and private.

Does resizing reduce image quality?

When resizing down (making smaller), quality loss is minimal. When resizing up (making larger), some quality degradation may occur depending on the original image resolution. The tool uses high-quality interpolation for the best results.

Are there any limits on file size or dimensions?

There are no artificial limits. You can resize images of any size, as long as your browser has enough memory to process them.

Do I need Photoshop to resize images?

No. This is a completely browser-based tool. You don't need Photoshop, GIMP, or any other software to resize images.
