How to use the Whiteout PDF
- Open your PDF letter, lease, or invoice to locate the misprinted date or typo.
- Drag an opaque white rectangle over the incorrect words to cover them on the page.
- Switch to "Text" to type the updated date, price, or name directly over the whiteout patch.
- Select "Download PDF" to save an updated document ready for sending to clients or tenants.
Quick typo corrections, letterhead updates, and replacement typing
Catching an error on an otherwise finished document can stall office workflows. By dragging an opaque white box over a wrong invoice total, expired policy number, or clerical typo, you create a blank canvas right where the mistake was. You can resize the whiteout box with its corner handles, drag it to match the line height, or nudge it with arrow keys (holding Shift for 10 pt jumps). If you place a box incorrectly, clear it using the Delete key or the bin icon, or undo the action with Ctrl+Z.
Once the erroneous passage is concealed, choose "Text" from the toolbar and click over the white patch to insert the corrected information. Choose Helvetica, Times, or Courier to match the existing typography, and set the font size from 6 pt to 96 pt (12 pt default). You can also set font colors to Black or Dark grey so the revised entry blends naturally with surrounding text. All adjustments run on your local computer via pdf.js and pdf-lib, protecting confidential office paperwork from remote uploads.
Critical honesty warning regarding visual masking versus real redaction
Placing a white box covers mistakes visually on the page, but original letters remain tucked inside the PDF code where people can copy or search for them, so it is not a redaction tool and should not be used to hide sensitive personal data. Office staff handling payroll records, personnel files, or medical forms must observe this rule carefully. Anyone opening the file in a browser or reader can still highlight the underlying letters with a mouse cursor, copy the obscured text to a clipboard, or discover it using search terms.
Selecting "Download PDF" embeds the white patches and overlapping new text into the document native page content. The newly typed words are standard, searchable text, while the original file remains safe on your hard drive as the download appends -edited.pdf to the filename. When dealing with major contractual overhauls or lengthy agreements requiring wholesale paragraph revisions, convert the file using PDF to Word instead. If a PDF requires an opening password, unlock it first using Unlock PDF.
Questions
Can staff rely on whiteout to remove sensitive student information or bank details?
No, the white patch conceals letters visually while leaving underlying text intact and searchable, which means it is not a redaction tool.
How do I type the right date over the whiteout box?
After drawing your whiteout box, click "Text" in the toolbar, tap above the white patch, and type the correct date or number.
Will the whiteout patch move or disappear when printed on an office printer?
No. When you select "Download PDF", the white box is written directly into the document content stream, so it prints identically on all printers.
