Add text and annotations to your PDF
Add text anywhere on a PDF without buying a licence or installing anything. Position a text box, type what you need, choose the font, size, and colour, and download the annotated document. It works for filling flat forms, labelling figures, adding notes, and marking up documents for review — free, in your browser, with no watermark.
PDFs were designed to look identical everywhere, which is exactly what makes them awkward to edit. A word processor stores text as flowing paragraphs; a PDF stores it as individual characters placed at fixed coordinates. There is no paragraph to reflow, which is why changing one word in the middle of a sentence is a genuinely difficult operation rather than a simple one.
What is straightforward is adding text. Placing new content at a chosen position does not disturb anything already on the page, and that covers the overwhelming majority of what people actually need: filling blanks, adding notes, labelling, correcting, and signing off.
This is the single most common use of the tool. Government departments, schools, clinics, and older corporate systems still distribute forms as flat PDFs — often scans of printed paper — with no interactive fields at all. The conventional route is to print the form, write on it by hand, scan it back, and email the result, which takes twenty minutes and produces a document nobody can read.
Instead, open the form here, place a text box over each blank line, and type your answer. The finished document looks typed rather than handwritten, stays perfectly legible, and never needs to touch a printer. For anything requiring a signature, Sign PDF adds a signature image to complete it.
Anyone facing an official form that was never made fillable — applications, registrations, claim forms, consent sheets. Teachers annotate worksheets and add feedback to submitted work. Reviewers mark up drafts with comments and corrections. Small businesses add reference numbers, dates, and notes to invoices and delivery notes. Anyone labelling a diagram or figure for a report or presentation.
Upload your PDF by dragging it onto the box or clicking to browse. Click where you want text to appear and a box opens at that point. Type your content and set the font, size, and colour. Repeat for as many text items as the document needs — each keeps its own independent formatting. When everything is in place, download the edited PDF.
Text you add is written into the document as genuine text rather than as a picture of text. That means it stays selectable, searchable, and copyable in any PDF reader, and it remains perfectly sharp at any zoom level instead of turning into a blurry bitmap when someone zooms in to read it. It also keeps the file size small, since text occupies a tiny fraction of what an image of the same content would.
For genuine revision of content already in the document, the reliable route is a round trip through a word processor: PDF to Word converts the PDF into an editable document, you make your changes in Word where reflowing text is natural, then Word to PDF converts it back. Complex layouts do not always survive perfectly, but for text-led documents this works well and is far less frustrating than fighting the PDF format directly.
This distinction matters and catches people out. Drawing a black rectangle over sensitive text hides it visually but leaves the words in the file, where anyone can recover them by selecting and copying the region. If you need information genuinely removed rather than merely covered, use Redact PDF, which deletes the underlying content rather than painting over it.
The page preview and your text placement are rendered locally in your browser. When you download, the file is processed in memory and discarded immediately afterwards. Nothing is written to disk, nothing is logged, and no copy is kept — which matters when you are filling forms with personal details.
