Questions

Does PDF watermark local upload my file to Rupeka?

No. The live tool reads and processes the selected file in your browser. Rupeka does not need a server upload, account, or database for this result.

Can I use the result for an official form?

Use it as a preparation aid and always check the exact size, format, and instructions shown on the official portal before submission.

Will my original PDF or images be changed?

No. The tool creates a new downloadable file in your browser and leaves every selected original untouched.

Should I check the downloaded PDF?

Yes. Open the result and review every page, number, watermark, crop, and file-size rule before official submission or sharing.

Can I control watermark appearance?

Yes. Enter text, choose opacity and font size, and select a diagonal or centered layout. The current built-in PDF font supports Latin letters, numbers, and common punctuation.
