When to Resize vs Crop an Image

Resizing scales the entire image while keeping all content. Cropping removes parts of the image. If you want to fit an image into a different size container while keeping all its content — resize. If you want to focus on a specific part — crop.

Common Resize Scenarios

• Email attachments: Reduce a 5MB photo to under 500KB by resizing to 1200px wide
• Website images: Resize hero images to exactly 1920×1080
• Social media: Each platform has specific required dimensions
• Profile photos: Standardize to 400×400 for consistency

Step-by-Step: Resize Online

1. Open Image Resizer.
2. Upload your image.
3. Enter target width and/or height in pixels.
4. Lock aspect ratio to avoid distortion (recommended).
5. Download the resized image.

Maintain Quality When Resizing Down

Reducing an image's size always results in some quality loss (fewer pixels = less detail). For web, resize to exactly the display size — never larger. A 300px-wide image displayed at 300px looks sharper than a 3000px image scaled down by CSS.
