Add text to a PDF
Add Text to PDF lets you type directly onto a page — fill in a form that isn't interactive, add a note, insert a date, or drop in a missing field. Place the text anywhere, pick the size, and save.
Everything is drawn on your device, so a document you're filling in never leaves your browser.
How to add text to a PDF in three steps
- Open the PDF you want to write on.
- Click where the text should go and type; move or resize it until it sits right.
- Save and download the PDF with your text baked in.
Why Add Text to PDF runs on your device
Everything happens on your device. The moment you choose a file, Add Text to PDF loads it directly into your browser's memory and does all the work there with WebAssembly and JavaScript — the bytes never travel to a server, because there is no server in the loop. FreePDFX enforces a strict Content-Security-Policy whose connect-src 'self' rule makes it physically impossible for this page to send your document anywhere, even by mistake. Want proof? Open your browser's Network panel and watch, or simply switch off Wi-Fi first. As an installable Progressive Web App, it keeps working fully offline once the tools are cached. FreePDFX sets no advertising or analytics cookies today, and keeps only small settings you can see and wipe any time — your PDFs are never among them, because they are never received.
Lossless — nothing is re-encoded
This is a lossless operation. Your original pages are copied byte-for-byte into the result, so text stays selectable, images keep their exact quality and vector graphics stay razor-sharp — nothing is rasterised, re-compressed or downgraded. Your text is added as a new layer over pages that are otherwise copied unchanged, so the rest of the document stays exactly as it was.
Free forever, with no sign-up and no watermarks on your results. FreePDFX exists to give you the everyday PDF tools you need without handing your documents to a stranger's server. Every tool is honest about what it can and cannot do, so you always know whether you are getting a byte-perfect result or a solid best-effort one before you download.
Frequently asked questions
Are my files uploaded anywhere?
No. Add Text to PDF runs entirely inside your browser. Your file is opened in local memory and processed with WebAssembly and JavaScript, and the site's Content-Security-Policy blocks every network connection except to FreePDFX's own files — so your document simply has no route off your device.
Does this work offline?
Yes. FreePDFX is an installable Progressive Web App. After your first visit the tools are cached, so you can add it to your home screen or desktop and keep using Add Text to PDF with the Wi-Fi off — nothing needs to download again.
Is there a file size limit?
There's no server-side limit, because nothing is uploaded. The only ceiling is your own device's memory: very large or high-resolution PDFs use more RAM, so an older phone handles less than a modern laptop. If a huge file struggles, close other tabs and try again.
Do I need to sign up or pay?
No. FreePDFX is free and needs no account, email or payment. Open a file and go — there's nothing to register, and no watermark is added to your results.
Can I fill a non-interactive form with this?
Yes. When a PDF has no fillable fields, Add Text lets you place typed text over the blanks and save a completed copy.
Can I move the text after placing it?
Yes. Reposition and resize each piece of text before you save.
