완전 가이드: PDF 오버레이

Overlaying PDFs combines two documents by placing the content of one on top of the other, page by page. This is commonly used to add letterheads, backgrounds, or templates to existing documents. For example, you can overlay your company letterhead onto a plain document, add a decorative background to a certificate, or merge a watermark template with your content. iLoveDoc's Overlay PDF tool gives you control over which document goes on top and the opacity of the overlay, ensuring the combined result looks exactly as intended. The overlay operation is applied page by page, with options for how to handle documents of different lengths. All processing happens locally in your browser.

PDF 오버레이 에 대한 자주 묻는 질문

What is the difference between overlay and merge?

Merging combines documents sequentially (pages after pages). Overlaying places content on top of each other on the same page.

Can I control the transparency?

Yes. You can adjust the opacity of the overlay layer to let the background show through.

What happens with different page counts?

If the overlay has fewer pages than the base, you can choose to repeat the last overlay page, use blank pages, or only overlay matching pages.

Can I overlay an image instead of a PDF?

Convert the image to PDF first, then use it as the overlay layer.

Is the overlay permanent?

Yes. The overlay creates a new PDF where both layers are merged into the page content.
