Add Text to PDF — How to Use It Online for Free
Add Text to PDF stamps the same text on every page of a PDF — CONFIDENTIAL, DRAFT, your name, a date or a notice. Choose a light diagonal watermark across the page, centred text, or a clean line at the bottom, with your own font size and opacity.
Watermarks do two jobs: they warn ('DRAFT — do not file this version') and they claim ownership ('Property of Sharma Coaching'). For documents that travel — quotations, designs, sample chapters — a light diagonal name across every page discourages misuse far better than a note on the first page. Bottom-position text suits formal additions like a reference number or date on every page.
How to use the Add Text to PDF
- Drop your PDF in, or click to choose one.
- Type the text to stamp — for example CONFIDENTIAL, or your name.
- Set the font size, opacity and position (diagonal, centre or bottom).
- Click “Stamp text & download”.
A quick example
You are sending a price quotation to a new client. Stamp 'QUOTATION — Sharma Traders' diagonally at about 25% opacity: every page carries your name, and the figures stay perfectly readable.
Tips for better results
- Short text stamps best — long sentences shrink into clutter across a page.
- Use DRAFT on unfinished documents; it prevents the most common version mix-ups.
- Stamp the final version only, after all other page edits, so content and page count are settled.
Working with PDFs online
PDFs are designed to look identical everywhere, which is why the whole world sends documents as PDF — and why working on them means changing the container rather than the content. The tools here handle the everyday container jobs: joining, splitting, ordering, stamping and numbering. Two habits keep PDF work painless. Keep your original file until you have opened and checked the result — every tool here creates a new file rather than changing yours. And do your edits in a sensible order: merge or split first, delete and rotate next, stamp after that, and add page numbers last of all, so the numbering matches the final document.
Common questions
What opacity should a watermark use? Around 20–35% is the sweet spot for a diagonal watermark: clearly visible, but the document underneath stays easy to read. For a bottom line like a name or date, you can use a higher opacity since it sits in the margin.
Can the stamped text be removed later? The text becomes part of each page in the new PDF, so it cannot be peeled off casually — that is the point of a watermark. Keep your unstamped original if you need a clean copy.
Are my files uploaded to a server? No. The Add Text to PDF runs entirely in your browser — your file is processed on your own device and is never sent to ToolNest or anywhere else. Close the tab and everything is cleared.
One tool rarely finishes the whole job. The natural companions to this one are covered in the PDF Merge guide and the PDF Split guide — between them, most PDF tasks can be handled end to end in the browser, with no installs and no accounts.
