These Terms of Service govern your use of PDF Stamp Generator, the browser-based PDF stamping tool, related content, and future paid downloads.
Use of the tool
The browser tool is provided to help you add image stamps, cross-page seals, visible signature marks, and page-specific marks to PDFs. You are responsible for reviewing the output before using it in business, legal, accounting, or compliance workflows.
File security
The default workflow is intended to process files locally in your browser. If a future server-side processing mode is offered, it should delete files after processing. You should not upload confidential documents unless you accept that processing method.
Advanced features
Cryptographic certificate signing, PDF encryption, and full flattening may require server-side software or the offline PDFQFZ.WPF desktop application. Browser-visible marks are not the same as legally validated digital signatures.
Paid desktop download
PDFQFZ.WPF download access requires login and a one-time $9.9 purchase. The final payment, refund, tax, and download rules may be implemented through WooCommerce, a membership plugin, or a payment provider.
Acceptable use
- Do not upload files you do not have permission to process.
- Do not use the site to forge signatures, misrepresent authority, or create unlawful documents.
- Do not attack, overload, scrape, or reverse engineer the service.
Limitation of liability
The site is provided on an “as is” and “as available” basis. To the fullest extent permitted by law, we are not liable for damages resulting from tool output, document misuse, or third-party payment/download services.
