Pilih halaman, posisi, atau watermark berulang. Gunakan layer di atas atau di belakang konten; objek halaman yang pekat dapat menutupi watermark di belakang.

Pertanyaan tentang Add Watermark

How do I add a watermark to PDF?

Choose your PDF, type a text watermark or select an image, adjust it in the live preview, and export. Text and images are added as PDF elements without rasterizing original pages.

Can I use an image as a watermark?

Yes. PNG and JPEG images are embedded locally; PNG transparency is preserved. WebP and JPEGs containing EXIF orientation data are decoded locally to PNG so their displayed appearance matches the output. Aspect ratio is preserved. SVG and remote image URLs are not accepted.

Can I adjust watermark transparency?

Yes. Opacity ranges from 0% to 100%, with 25% by default. Zero opacity is invisible. The preview uses the actual source page transparency, including opaque objects that may cover watermarks behind content.

Can I add a diagonal watermark?

Yes. Diagonal Center uses a −45° rotation. You can use the rotation slider, quick angle buttons, or horizontal/vertical/tiled patterns. Dense patterns have per-page and per-document resource limits.

Can I watermark only selected pages?

Yes. Choose selected thumbnails, first/last page, odd/even pages, or a custom range. Exclude First / Cover Page is also available. All source pages remain in the output.

Does a watermark protect confidential PDF content?

No. Visible watermarks are not access control, encryption, or proof of ownership and may be removable. They can label or personalize a document, but do not make it safe to disclose confidential content.

Are PDFs or watermark images uploaded?

No. The entire workflow runs in your browser, using self-hosted PDF and font modules. Files, names, images, document text, and metadata are not sent to a server or analytics. Source files remain unchanged. Changes can invalidate digital signatures; detected signatures and unsupported document structures require confirmation.
