How to use Edit PDF

Best practices for reliable results
- Keep an untouched backup of the source file.
- Only process documents you have permission to use and share.
- Review every page of the output, not just the first page.
- Check text, layout, page order, links, fields and images where relevant.
- For important work, compare the output with the original before distributing it.
Limitations to know
PDF editing capabilities vary by tool. A browser editor may not preserve every font, layer, annotation or interactive object. For complex layouts, inspect the output closely.
