Troubleshooting
Common Watermark PDF Problems
Why can’t I edit some content?
Some PDFs contain flattened artwork, scans or embedded fonts rather than editable source objects.
Why did an annotation move?
Coordinates can be affected by page rotation, crop boxes and mixed page sizes. Inspect every changed page.
Will the original file be changed?
The browser workflow creates a new output. Keep the source and use a clear filename for the edited copy.
Why does the result vary by viewer?
PDF viewers handle forms, annotations, transparency and fonts differently. Test the final file in the recipient's viewer.
