When to use image resizer
A photo that looks right on your phone may be too large for a form, profile or product listing. Set the dimensions your destination requires. Keep the aspect ratio to avoid stretching, or turn it off when you deliberately need a different shape. The output dimensions are checked before the file is offered for download.
How it works
- Choose a PNG, JPEG or WebP image.
- Enter the width; keep proportions on to calculate height automatically.
- Choose an output format, resize and download the result.
Try this example

Before you export or rely on the result
Upscaling adds pixels, not detail. Images are limited to 25 MB and 24 million decoded pixels. JPEG output uses a white background for transparency.
