This is helpful for passport photos, visa photos, identity documents, certificates, printed forms, signatures, and document uploads.
Crop Images Online
Before resizing, you can crop the image to remove extra background and keep the important part properly framed. The crop tool helps with passport photos, profile pictures, document photos, signatures, thumb impressions, and ID images.
You can also rotate the image or use fine rotation to improve alignment before processing.
