Why pick Convertify for this?
Files stay on device
Convertify processes everything in your browser using JavaScript. Your file is never uploaded — confirm with DevTools → Network. That makes this safe for sensitive material like contracts, IDs, and financial documents.
No upload wait
Because nothing uploads, processing starts the instant you click. For typical files (under 50 MB) the whole job finishes in seconds — no progress bar, no queueing behind other users.
No daily quota
Free without limits, including no "3 conversions per day" cap that competing services impose. Run as many watermark pdf jobs as you need.
No watermark
Your output is clean — no Convertify branding, no metadata stamp. Same as if you'd run a paid desktop app.

Frequently asked questions
How do I add a watermark to a PDF?⌄
Upload your file, enter watermark text (like "Confidential" or "Draft") or upload a logo, set the position and opacity, then export.
Can I watermark every page at once?⌄
Yes. The watermark is applied across all pages in one step, which is ideal for branding or marking drafts.
Can I control transparency and angle?⌄
Yes. You can adjust opacity, size, rotation, and placement so the watermark is visible without obscuring the content.
Can I use my company logo as a watermark?⌄
Yes. Upload a PNG or JPG logo to overlay it as an image watermark on the document.
Is watermarking private?⌄
Yes. The process runs in your browser, so your document is never uploaded.
