TiPDF provides a focused PDF editor for a common, well-defined task: placing a new text note on one or more existing pages. The note is drawn near the upper-left of each selected page in Helvetica, using the font size you choose. That makes the PDF editor useful for adding a short status, reviewer label, reference number, correction note or other visible overlay without rebuilding the source document.
The current PDF editor does not select, delete, replace or reflow text that is already stored inside the PDF. Existing paragraphs may be split across font objects, drawing commands or scanned pixels, so editing them like a word-processing file requires a different reconstruction workflow. This tool adds content; it does not pretend to rewrite the original text layer.
Every successful edit creates a new download. Your source remains on your device, and the output name identifies it as an edited copy. This separation helps when a contract, worksheet or report must remain available for comparison. For comments, use PDF Annotator; for existing AcroForm fields, use PDF Form Filler.
