Common questions about PDF workflows.
How do I merge PDFs?
Go to PDF Tools, choose Merge, upload files, reorder if needed, then download the final PDF.
Why is my PDF output blank?
This can happen with unusual PDFs (scanned images, broken fonts, encryption). Try re-saving the PDF, removing password protection, or converting via “Print to PDF” and retry.
What are page/job limits?
Limits depend on your plan (Guest/Free/Plus/Pro). Signed-in accounts typically have higher limits and usage history.
Document Merge (Mail Merge)
Templates and data files.
How do placeholders work?
Put placeholders like
{{name}}
in your template. Your CSV/Excel must contain a column named name.
My merged files show empty fields. Why?
Usually the placeholder name does not match the column header. Check spelling and remove extra spaces in headers.
What file types are supported?
Typically: DOCX/PDF templates and CSV/Excel data sources (depends on your current implementation).
