How to resize an image
Resizing changes an image’s pixel dimensions. Smaller dimensions are useful for websites, email and forms, while an exact width and height can help meet upload requirements.
Step-by-step
- Choose an image and enter the required width or height.
- Keep the aspect ratio locked when you want to avoid stretching.
- Select JPG, PNG or WebP, resize the image and check the downloaded result.
Tips for a better result
- WebP often gives a small web-friendly file with good quality.
- JPG suits photographs; PNG suits graphics, text and transparency.
- Avoid enlarging a small image too far because it can look blurred or pixelated.
