Frequently asked questions

How do I resize an image?

Choose an image, enter the new width or height in pixels, and click Resize. Keep “Lock ratio” on to scale proportionally, then download the resized image.

How do I resize an image to exact pixel dimensions?

Turn off “Lock aspect ratio” and type both the width and height you need, for example 1080 × 1080. The image is resized to those exact dimensions.

Will resizing stretch or distort my image?

Not if “Lock aspect ratio” is on, the other dimension adjusts automatically to keep the image proportional and undistorted.

Can I make an image bigger without losing quality?

You can enlarge an image, but going beyond its original size can look soft because there is no extra detail to add. For best results, resize down rather than up.

Are my images uploaded to a server?

No. Resizing happens in your browser, so images stay on your device, completely private.

Is the image resizer free?

Yes, completely free with no sign-up or watermark.
