When server processing is needed, files are encrypted during transfer, processed in an isolated environment, and deleted immediately after your download completes. We never access or store your content.
To replace existing text in a PDF, first use the Whiteout tool to cover the original text with a white rectangle, then add new text on top. Match the font size and style to the surrounding text for a seamless result.
