Drop a solid black box over any name, number or line you want hidden — or redact it permanently. It all happens in your browser; the file never leaves your device.

A black-out box is a solid filled rectangle you drag over the words — the classic censored look. It hides the text visually and prints exactly as you see it, which is perfect for a quick screenshot, a shared draft or covering a figure before you send it round. What it does not do, on a digital PDF, is delete the words underneath: they can still sit behind the box and, in some cases, be copied or searched back out.
So when the text is genuinely sensitive — a bank account, an address, a name that must never leak — reach for redaction instead. In DollarFix PDF the redact tool draws the same black bar but strips the underlying content out for good, so there is nothing left to recover. Use a plain black box to tidy the look; use redact when the words themselves have to disappear. Both live in the same editor, so you can decide box by box.
You do all of this without uploading anything. Your PDF opens and stays on your own machine — no account, no sign-up, no card on file. Editing is free; you pay a one-off $1 only when you download the finished file, with no subscription and no watermark.
