PDF File Magic Editor 作者： ziddyangus

PDF Editor lets you change the text that's already in a PDF. Click any line, type your change, and it's written back in the document's own font, so it looks exactly like the original.

What it does
- Edit existing text in place, in the PDF's own font and colour
- Add new text, images, highlights, whiteout boxes and freehand drawing
- Undo/redo, zoom, drag-and-drop, keyboard shortcuts
- Save a new copy — the original file is never changed
