What PDF Overlay does
Free PDF Overlay. Place pages from one PDF on top of another (useful for letterheads or stamps). Runs 100% in your browser — no file uploads, no account required, no watermark added. Free and unlimited on PDFStudio Pro.
PDF Overlay is an optimize-style tool: the goal is a smaller, cleaner or more practical file while keeping the document usable.
How to use PDF Overlay
- Upload base PDF and overlay PDF.
- Click Overlay.
- Download the result.
Practical examples
- Run PDF Overlay when you need a quick result without installing desktop software.
- Use PDF Overlay on a shared computer — nothing stays after you close the tab.
- Process a pdf-related task privately in the browser and download only the output.
Tips for better results
- Prefer the original PDF when possible; re-saving multiple times can degrade image-heavy files.
- If a file fails, try a smaller range of pages or a single file first to isolate the issue.
- Keep a copy of the source file until you have checked the download.
Privacy and limits
PDFStudio Pro is built so core tools can run in your browser. That means the file you select is handled in the current tab whenever the tool supports local processing. Very large files depend on your device memory. After you download the result, close the tab if you do not want the data kept in memory.
FAQ — PDF Overlay
Is PDF Overlay free on PDFStudio Pro?
Yes. You can use it without creating an account. No watermark is added to the files you download from this tool.
Does PDF Overlay upload my files to a server?
The main workflow is designed to run in your browser. Your file is read locally in the tab whenever the tool supports fully client-side processing.
What file types does PDF Overlay accept?
Use the formats shown on the tool panel for PDF Overlay. If a file is rejected, convert or re-export it to a common format and try again.
Why is PDF Overlay slow on my phone?
Phones have less memory than desktops. Use a smaller file, close other apps, or run the same tool on a computer for large jobs.
