Συχνές ερωτήσεις

Is this PDF watermark tool free?

Yes. You can add text or image watermarks to PDF files for free, with no account and no paid third-party watermarking service.

Can I add a logo watermark to a PDF?

Yes. Upload a PNG or JPG image and choose its size, opacity, rotation, placement, and whether it repeats across the page.

Does watermarking reduce PDF quality?

No quality reduction is added to save server load. The tool imports the PDF pages and draws the watermark on top instead of rasterizing pages into images.

Can I watermark only selected pages?

Yes. Use page ranges like 1, 3-5, or 2-z to watermark selected pages.

Ποιο είναι το μέγιστο μέγεθος αρχείου PDF;

Μπορείτε να ανεβάσετε αρχεία PDF έως 1 GB, το ίδιο όριο μεταφόρτωσης που χρησιμοποιούν τα εργαλεία του Convertr.

Are watermark text, logos, or filenames sent to analytics?

No. Analytics records safe buckets such as watermark type, placement, file size, page count, and failure reason. It does not record filenames, watermark text, logo content, or PDF content.
