How to Annotate, Blur Sensitive Areas, and Markup Screenshots Online

Frequently Asked Questions

Can someone un-blur or recover the text I blurred out with iEditPDF?

No. iEditPDF's blur filter calculates a true mathematical Gaussian blur/pixelation matrix over the pixel data. Once exported, the original underlying pixels are permanently destroyed and cannot be reversed.

Can I paste a screenshot directly from my clipboard without saving it first?

Yes! Take a screenshot on your computer (Windows Snipping Tool or Mac Cmd+Shift+4) and simply press Ctrl+V / Cmd+V on the editor page to paste it instantly.

Do I need to download or install any photo editing software?

No. The entire photo markup editor runs 100% inside your web browser without plugins, extensions, or software installations.
