How to use it
- Choose a PDF and select the target page.

- Apply the overlay, download the copy and verify the page.
Supported input

Limitations
- This overlays content; it does not edit or reflow existing PDF text.
- Coordinate placement may require adjustment because PDF origins start at the bottom-left.
Troubleshooting
- Use smaller coordinates if an overlay falls outside the page.
- Use PNG for overlay artwork that requires transparency.
Tool-specific questions
Can it change existing words?
No. It adds new content above the existing page.
Can I make several edits?
Apply and download one configured overlay at a time in this initial editor.
Before you process
Can I use this edit pdf online without uploading my input?
Yes. This tool is labelled On-device, so the selected input is processed in your browser and is not sent to a Locrivo processing API.
What happens if the browser cannot process it?
The tool shows a readable error and stops. It does not silently fall back to a cloud upload.
Why can performance differ between devices?
The browser is doing the work locally, so speed and practical file size depend on available memory, CPU and browser capabilities.
