Your document stays on your device. Nothing is uploaded.
Open a document, click any line of text, and type what it should say instead. The replacement picks up the background and ink colour from the page around it. Everything happens inside this browser tab.
This is not redaction. Replacing text covers the original rather than removing it, so the old wording stays inside the file and can be recovered. Never use this to hide confidential information.

A PDF does not store paragraphs the way a word processor does. It stores instructions that place individual characters at fixed coordinates on the page. There is no sentence to rewrite and nothing that can reflow, which is why PDFs have a reputation for being awkward to change. What this tool does instead is work out exactly where a piece of text sits, cover that area in the background colour of the page, and draw your replacement in the same position using the closest matching font. For a date, a name, a figure or a typo the result is indistinguishable. For a long passage in a distinctive brand typeface it will not be, and the tool tells you when it thinks the replacement is too wide for the space it has.
Covering text is not the same as removing it. When you replace a line here, the original wording is still present in the file underneath, and anyone can recover it by selecting the text or running a simple script. This has caught out law firms, government departments and newspapers, sometimes very publicly. If you need to permanently remove sensitive information from a document, you need a tool that deletes the underlying content rather than hiding it, and you should verify the result by trying to select the text afterwards.
No. Everything happens inside your browser, so your document stays on your device. Once this page has loaded you can disconnect from the internet and it will still work.
It matches the closest standard font, which is Helvetica, Times or Courier, along with the size, weight and colour of the original. If the document uses a distinctive brand typeface the replacement will not be an exact match, because that font is only partially embedded in the file and cannot be used to draw new characters.
No. Because text sits at fixed coordinates, you can change what a piece of text says but the text around it will not move to accommodate it. If your replacement is wider than the original, the tool warns you and offers to shrink it to fit.
Pages that have been rotated are not editable, because the replacement cannot be placed reliably on them. Scanned pages are also not editable, since the text in a scan is part of an image rather than real text.
Locking draws your changes into the page itself, so the file looks identical in every PDF reader and the edits cannot be undone. Keeping them editable adds them as annotations, which Acrobat and Preview let you click and change later, though some lightweight readers display annotations differently.
