How to Resize Your Image

Follow these simple steps to get your images ready for any application form.

1

Upload Your Image

2

Choose a Preset or Target Size

Select one of the common presets ("Photo", "Signature", etc.), or go to "Advanced Options" and use the "Target Size" slider to set an exact size in KB.

3

(Optional) Set Dimensions

If you need specific dimensions (like 3.5cm x 4.5cm), you can also enter the exact pixel width and height in the Advanced Options. The aspect ratio is locked by default to prevent distortion.

Frequently Asked Questions

Is this service free?

Yes, this image resizer is completely free to use.

Are my images saved on your server?

No. All image processing is done directly in your browser. Your images are never uploaded to our servers, ensuring your privacy and security.

How do I convert cm to pixels?

The conversion depends on the DPI (Dots Per Inch). A common standard is 300 DPI. For example, a 3.5cm x 4.5cm photo at 300 DPI would be approximately 413 x 531 pixels. You can use an online calculator for precise conversions if needed.

What if the resized image is still too large?

The app tries its best to get below your target size. If the result is still slightly over, try reducing the "Target Size" in the advanced options by a few KB and resize again.
