Why compare your images on PDFDocks?
Comparing two versions of an image — before and after an edit, two similar photos, or two designs — is much easier when overlaid than when switching between tabs. PDFDocks lets you upload two images and slide a control to reveal one over the other, all directly in your browser. Neither image is uploaded to any server: the comparison is generated with JavaScript on your own device, so you can compare personal photos or documents without worrying about their privacy.
Is it safe to compare images online with PDFDocks?

Can I download the comparison result?
