Preview vs a browser editor
- Preview adds text boxes, shapes, highlights and signatures over the page. A white box with typing on top is a second layer: it can show against a tinted background or in print.
- This editor rewrites the line in place, in the document’s own font where the file allows, and marks a block Overlay only before you type when it can only draw over the old text.
What you need
- A PDF under 5 MiB (25 MiB on Pro), up to 100 pages
- A desktop browser (upload and download only on a phone)
- Text you can select — not a scan
- A free account, with a confirmed email, to download
Steps on a Mac
- Open the editor in Safari, Chrome, Firefox or Edge.
- Drag the PDF from Finder onto the box, or click Choose a PDF.
- Double-click the text and type.
- Export PDF; your browser saves it, usually to Downloads.
iPhone or iPad: the editor does not open on a phone or touch tablet, but you can upload there and, signed in to the same account on both, find the file in Your documents on the Mac.
