How does the certificate cleaner remove shadows from mobile photos?

The tool uses adaptive background whitening algorithms to distinguish dark printed ink from uneven lighting gradients, rendering paper backgrounds pure white while keeping printed stamps and signatures clear.

Will government seals and official stamps remain legible?

Yes. You can select Clean Colour mode to preserve colored rubber stamps and official seals while only whitening the plain paper background.

What output formats are supported?

You can export your cleaned document as a high-resolution JPG image or directly as a clean A4 PDF file ready for portal submission.

Are my educational certificates uploaded to a cloud server?

No. All image adjustments and PDF exports take place inside your device browser memory. Your academic documents remain completely confidential.
