Details and limits

Upload a still JPG or PNG logo or mark. Its width is a percentage of the visible page area inside the margins. The image keeps its aspect ratio and shrinks further if needed to fit the page height.

Keep your original file and review the export. Signed or certified documents are not supported. Restructuring pages does not support interactive forms and may lose bookmarks, document attachments, or cross-page links. Watermarks and numbers cover content; they do not redact or secure it.
