Vellum lets you correct the existing text of a PDF document with no software to install. Every detected passage becomes editable: you click it, you rewrite it, and the original text is deleted from the file produced rather than simply covered over. Processing happens entirely in your browser: the document is never sent to a server.
Open the PDF in the tool and click the passage you want to correct: it becomes an editable field. Retype the text, then download the corrected file — the original text is deleted from the document, not just covered up.
No. Unlike a plain white box placed on top, the tool actually removes the old text from the PDF’s content stream before inserting the new one. There’s nothing left to copy or extract.
No, all processing happens locally in your browser. The PDF never leaves your device, which suits confidential documents, and the tool is free to use.
