What This Processing Changes
Each PNG is placed on a PDF page. Transparency may be flattened against a page background, and the result is not an editable text document.
How to Check the Result
- Expect two pages in this sample.
- Check the visible content and page margins; embedded pixels are not editable text.
Limits and Troubleshooting
- Arrange images before conversion because page order follows the upload list.
- Very large pixel dimensions can make a PDF heavy even when the page size looks normal.
