Image Resizer

About Image Resizer

Upload slots, avatars, websites and print jobs all demand exact pixel dimensions - and a 4000px photo where 1200px is needed is pure waste. This tool resizes your image to the width or height you specify, keeping the aspect ratio automatically so nothing stretches or squashes.

How Image Resizer works

1. Upload the image.
2. Enter the target width or height - the other dimension follows automatically.
3. Download the resized image.

Features

• Exact pixel dimensions on demand
• Aspect ratio preserved automatically - no distortion
• Shrinking also reduces file size for uploads and email
• Pairs with Crop Image when a specific ratio (like a square avatar) is required

Tips for best results

• Common web targets: 1920px wide for full-width banners, 1200px for article images, 400-800px for thumbnails and avatars.
• For passport or ID photos, follow the exact pixel and ratio specification from the issuing authority - crop to the ratio first.
• Never enlarge for print; a small image stretched to poster size will look blurry no matter the tool.

FAQ

Can I enlarge a small photo?

Technically yes, but it will blur - enlarging invents pixels that do not exist. Resizing is for making images smaller or matching a required size.

How do I get an exact ratio like 4:6 or a square?

Crop to the ratio first with the Image Cropper, then resize to the pixel dimensions needed.

Does resizing reduce file size too?

Yes - fewer pixels means a fundamentally smaller file, often more effective than compression alone.
