- Download the resized images. Change the size at any time and they update instantly.
Resizing without distortion
Enter a maximum width, a maximum height, or both. Each image is scaled down to fit inside those limits while keeping its original aspect ratio, so nothing gets stretched or cropped.
Common sizes: 1920 px wide for full-screen web images, 1200 px for blog posts and social media, 800 px for email attachments, 400 px for thumbnails.
Good to know
- Images smaller than the limits are not enlarged, so they keep their sharpness.
