Every line of text becomes an editable text box in the same place and size; the original is covered with a white patch. Then double-click a line to type.
Limits: the font becomes a standard font (Helvetica, Times or Courier), lines stay put, and the original text remains invisibly present in the file. Undo with Ctrl+Z.
Careful with a scan: in a scanned PDF the text sits invisibly on top of the scan. The white boxes then cover the scan itself and you are left with the recognised text, including its mistakes. Check the result, or undo with Ctrl+Z.
Select an element or pick a tool — the formatting options adapt here.
Add text, shapes, highlights and signatures, or black out parts: all in your own browser.
Choose a tool in the ribbon and click or drag on the page. Select = move/resize · Delete = remove (a selected thumbnail = that page) · Ctrl+Z = undo · right-click a thumbnail for page options. Redact turns the page into an image on download (the text really disappears).
Position relative to the top-left corner of the page.
Export with all annotations burned in (exactly as you see them).
This tool runs entirely in your browser: your PDF is not sent to a server. A password-protected PDF will not open here; remove the protection first with the Unlock tool.
