Frequently Asked Questions
Can I merge a password-protected PDF?
Use unencrypted PDF files. The tool has no password field or supported unlocking workflow.
Can I change the order?
Yes. Reorder the uploaded files with the on-page controls before converting. All pages within each file keep their original sequence.
Will it compress my PDF or skip blank pages?
No compression preset or blank-page removal is applied. Blank pages are copied along with the rest of each source document.
Are forms, signatures, bookmarks, or metadata preserved?
Page appearance is copied into a new PDF, but document-level features are not guaranteed. Test any features you rely on and retain the originals.
What is the upload limit?
The default limit is 50 MiB per file. Check the upload area for the current limit. The server upload ceiling is 100 MiB per file; file complexity and processing time can also limit conversion.
Where are files processed and when are they removed?
This tool uploads files to Zutilium's server for processing. After a successful conversion, uploads are scheduled for deletion after about one minute and generated downloads after about ten minutes. Cleanup runs periodically, so removal is not immediate. Save your result promptly.
