Frequently asked questions
How do I tell it which file is the PDF and which is the image?
Just add both — the tool detects them automatically by type. One PDF and one image (JPG or PNG) is the expected combination.
Does it keep the image transparency (PNG)?
Yes. PNG transparency is preserved, so a logo with a transparent background sits cleanly over your page.
Can I put the image only on the first page?
Yes — type “1” in the pages field. Leave it empty to stamp the image on every page (useful for letterhead logos).
Is it safe to use this tool with confidential documents?
Yes — and verifiably so. PDFAgent has no upload step: your file is processed by JavaScript running in your own browser and never leaves your device. You can open your browser’s network panel (or even go offline after loading the page) and confirm that no document data is transmitted.
