How to use this tool
Add a new text label, a drawn signature, an uploaded picture, a rectangle, line or highlight to selected pages. Position is measured in points from the top left. Existing text remains unchanged, and covering it does not remove it.
A FEW SIMPLE STEPS
From file to finished.
Make it yours
Adjust the settings. Processing happens on your device.
Save the result
Download a new file. Your original stays untouched.
Do you upload my files?
No. The selected file is read and processed by your browser. The site downloads its own code and libraries, but never sends your file contents to a server.
Why might a file fail?
A file may be damaged, encrypted, use an unsupported codec, or exceed your device’s available memory. The file picker limit is 100 MB per file (5 MB for text). This limit is not a guarantee that every device can process every file. Try a smaller file and a current browser.
Do I need an account?
No account or payment is required. Close the page to discard the workspace. Favorites and ad preferences are stored locally; file contents are not.
