How to resize
- Open the Image Resizer and add your photo.
- Enter a new width or height. Keep the aspect ratio locked so the image doesn't stretch.
- Download the resized image.
Aspect ratio: the thing people get wrong
If you force both a width and a height that don't match the original proportions, the image stretches and looks distorted. To change the shape (say, a landscape photo into a square), crop first with the Image Cropper, then resize the cropped result.
Upscaling has limits
Making an image larger than its original can't add detail — it just enlarges existing pixels, so it looks soft. Start from the highest-resolution original you have.
After resizing
Run it through the Image Compressor to keep the file small.
