What you can edit in a PDF
PDF editing covers two different jobs: adding new content on top of a page, and changing content that is already there. The editor handles the first — text, images, highlights, drawings and signatures — while Find and Replace changes existing words across the document.
Adding content
Place text boxes anywhere with a choice of font, size and color, which is ideal for filling in forms that are not interactive. Insert images such as logos or stamps, highlight passages for review, draw freehand notes or circles, and add a signature. Undo and redo let you experiment without starting over.
Changing existing text
Find and Replace searches the text of a PDF and replaces matches in the same position and style, which is the fastest way to correct a recurring typo or update a name throughout a document. Scanned pages are images, so their text cannot be edited directly; convert them with OCR first if you need to change the wording.
Saving your work
Additions are flattened into the page when you download, so the result looks identical in every viewer and prints exactly as shown. Your original file stays unchanged, so keep it if you may need another round of edits.
Editing tips
- Match the document's font and size when filling in forms.
- Use highlights and notes for review, then remove them from the final copy.
- Convert to Word instead when you need to rewrite large sections.
