The risk
Many online tools upload your picture to their server. That is a privacy risk for ID photos, signatures and documents, because you do not control what happens to the file afterwards.
Look for in-browser processing
Tools that run in your browser do the work on your own device, so nothing is sent. PicFitter works this way: the image is processed locally in your browser tab.
How to check
Open your browser developer tools, go to the Network tab, run the tool and see whether your file is sent anywhere. Or turn off the internet after the page loads and see whether the tool still works.
Other checks
Read the privacy policy, avoid tools that require sign-in for a simple task, and be careful with ones that add watermarks or ask for payment details.
