Best practices before you convert
Choose visible but readable watermarks
A good watermark identifies the document without making the main content hard to read. Use opacity and rotation carefully, choose whether every page or only a page range needs the mark, and preview before downloading.
Text watermarks are best for draft labels and confidentiality notes. Image watermarks are useful for logos or brand marks.

Can I add an image watermark?
Yes. Upload PNG, JPG, JPEG or WEBP images and LiftPDF will place the image watermark on each page.
Can I add a text watermark?
Yes. You can enter custom text, choose a standard font, adjust size, color, opacity, rotation and position.
Can I repeat the watermark across the page?
Yes. Use Tile / Repeat to place the watermark multiple times across every PDF page.
Can I watermark only selected pages?
Yes. Apply the watermark to every page or enter a page range such as 2-5 or 1,3,7.
Can I control opacity and rotation?
Yes. Text and image watermarks both support opacity and rotation controls with a live preview.
Will the PDF quality change?
LiftPDF keeps the original PDF pages and adds the watermark on top. Page dimensions and existing content are preserved.

Password-protected PDFs must be unlocked first with Unlock PDF before adding a watermark.
Are my PDFs uploaded to a server?
No. Preview and watermark generation run client-side with PDF.js, canvas and pdf-lib.
