IDPhoto4You.com is an instant online photo studio that lets you upload your own picture and create standard passport photos.
Using it is quite easy. Select the country, the photo type and the print size and then upload the photo you want to use. Once the photo is uploaded, the Crop page opens.
The software uses face detection to accurately crop your face. But if you are not satisfied with the automatic crop you can manually adjust the cropping. When you have set the cropping, click on the Make Photo button. Download the printable image which you can either print using a photo printer or get it printed in photo lab.
While you get the job done in any photo editor, IDPhoto4You has one distinct advantage – choosing the photo sizes. You just have to select the country and the photo type, the tool does the rest. For instance, if you select India, you have the following photo types to choose from.
So you just have to choose whether you want a photo for a Passport, Visa, Overseas Citizenship or a PAN Card.
You can find a detailed guide on using the tool here.
