Marca de agua PDF con logo — Estampado de marca en todas las páginas

Preguntas Frecuentes

Can I add my logo as a watermark to a PDF?

Yes — our PDF Watermark tool supports image watermarks including logos. Drop your PDF, drop your logo PNG (transparent background works best), drag it to your preferred position, adjust size and opacity, and save. The branded PDF is ready in seconds.

What logo format works best?

PNG with transparent background is ideal — it stamps cleanly without white boxes around the logo. SVG works for vector logos but renders to PNG during stamping (sharp at any size). JPG/PNG with backgrounds also work if you want the watermark to include the logo's background. For best print quality, use PNG at 2× the display size (e.g. 600px for a 300px display).

Where should the logo go for best effect?

Three common placements: (1) corner — small logo in bottom-right at 50-70% opacity (subtle, professional, used for proposals/invoices); (2) center diagonal — large logo across the page at 15-30% opacity (assertive, used for anti-copy brand protection); (3) tile — repeating pattern across the page (anti-copy strong). We support all three.

Can I use the same watermark on many PDFs?

Yes — our tool saves your watermark settings (logo + position + size + opacity) to browser localStorage for reuse. Apply the same brand stamp across invoices, proposals, and other documents with one click. Stored only on your device, never uploaded.

Will the watermark look good in print?

Yes — we use vector rendering via pdf-lib. The logo prints at the resolution you specify (150/200/300 DPI) without pixelation. Embed your logo at the highest resolution you have — output PDFs will scale it to the chosen size without quality loss.

Is my logo or PDF uploaded?

No — nothing leaves your device. Both your logo and your PDF are processed locally. For brand assets and confidential documents, this is the safest workflow. Even saved watermark presets stay in browser localStorage only.
