Resize Image Online

Change image width and height with optional aspect ratio lock and quick presets.

Frequently Asked Questions

Will resizing reduce quality?

Downscaling generally looks fine. Upscaling beyond original size may appear blurry because new pixels are interpolated.

What happens when aspect ratio is unlocked?

The image is cropped to your target size. Drag inside the frame to reposition, scroll to zoom — never stretched.

Can I resize for Instagram?

Yes. Use the Instagram preset or try our dedicated Instagram resizer.

Is this tool private?

Yes. Images are processed locally and never uploaded.
