Do I need an account or signup?

Is there a watermark on the output?

Output from this tool is not watermarked by PDFBaba. You get a clean file suitable for work and sharing.

What is the maximum file upload size?

The default limit is 100MB per file on the server. Your host or administrator can change this via environment configuration. If a file fails to upload, try compressing or splitting it first.

Can I use this tool on my phone or tablet?

Is there a daily usage limit?

To keep the service fast for everyone, rate limits may apply per IP. Typical personal use is rarely affected. If you hit a limit, wait briefly and try again.

What if my PDF is password-protected?

For Add Watermark, use an unlocked PDF when possible. If the file asks for a password in a reader, unlock it with our Unlock PDF tool first, then run Add Watermark on the decrypted file.

Why use Add Watermark?

Draft, confidential, and sample labels reduce misuse when PDFs circulate early. Watermarking overlays text or images across pages with opacity and range controls so you can mark only the sections you need. PDFBaba keeps the workflow online without signup and does not add its own branding to your file beyond what you configure. Files are deleted after about one hour. For one-off approval stamps rather than tiled backgrounds, consider the Stamp PDF tool, which behaves more like a foreground seal than a repeating watermark.

Supported files & limits

One PDF; add text or image watermarks. The default upload limit is 100MB per file; administrators can raise or lower this via server configuration. Controls include opacity and page ranges for drafts and branding.

Privacy & data retention

PDFBaba is built for quick tasks: your uploads and generated downloads are kept only long enough to process your request and are automatically deleted after about one hour. We do not require signup for these tools, and we do not use your documents to train AI models. For full details on cookies, analytics, and legal terms, read our Privacy Policy.
