Removing Personal Information One of the most common reasons to remove text from a PDF is to strip personal data before sharing. You might need to erase a name, phone number, email address, home address, or ID number from a contract, invoice, form, or letter. Since ConvertKr processes everything in your browser, your personal data is never transmitted anywhere — making it the safest approach for this kind of sensitive edit.
Text Removal vs. Redaction Traditional PDF redaction tools black out text while also stripping the underlying text data from the file. ConvertKr's approach is different: it re-renders modified pages as images with the marked areas filled, which means the original text data is completely replaced — not just visually covered. This makes the erasure permanent and the text unrecoverable on processed pages, which is exactly what you want when removing sensitive content.
Tips for Precise Text Removal For the cleanest results, draw your box tightly around the text you want to erase. Leave a small margin around the text to ensure complete coverage, but avoid extending into adjacent text you want to keep. If you need to remove a single word within a line, zoom into the page for better precision. White fill mode works best on most documents. If you accidentally mark the wrong area, use the Undo button to remove the last mark.
