Frequently asked questions
Can I add a watermark to every PDF page?
Yes. Choose All pages, or narrow the job with odd/even pages, a custom range, or exclude the first or last page.
Can I add a logo to a PDF?
Yes. Upload a PNG, JPEG, or WebP logo on the Image tab, then drag, resize, and rotate it on the live preview.
Can I watermark only selected pages?
Yes. Use Odd pages, Even pages, or a custom range such as 1-3, 5, 8-10. Thumbnails show which pages will receive the watermark.
Can I create a transparent watermark?
Yes. Lower the opacity slider for text or image watermarks. Semi-transparent marks are ideal for drafts and confidential documents.
Can I repeat a watermark across the page?
Yes. Enable Tiled watermark in Advanced to repeat the mark with adjustable spacing and staggered rows.
Are my files stored?
No. Watermarking runs in your browser. Files are not uploaded or stored by Utilnivo.
Can I watermark multiple PDFs?
Yes. Open Add More Files (Batch Watermark), add PDFs, then download each file or a ZIP of all results.
Will the original PDF quality be preserved?
Yes. Page dimensions stay the same and the watermark is drawn onto the existing pages without re-encoding page content as images.
