Frequently Asked Questions
5 Q&AQ1:How many PDF files can I merge at once?
There's no strict limit on the number of PDF files you can merge. The tool processes everything in your browser, so the main limitation is your device's available memory. Most users can easily merge 10-50 files depending on their size.
Q2:Will merging PDFs reduce the quality of my documents?
No, our PDF merger preserves the original quality of all documents. The tool combines files without recompressing images or altering text, ensuring your merged PDF maintains the same quality as the original files.
Q3:Can I change the order of pages before merging?
Yes, you can drag and drop files to reorder them before merging. The final PDF will contain the pages in the order you arrange the files, giving you complete control over the document structure.
Q4:What happens to bookmarks and hyperlinks in merged PDFs?
The merger preserves internal links within each original document, but bookmarks and cross-document links may not work as expected in the merged file. For complex documents with extensive navigation, consider using professional PDF software.
Q5:Is there a file size limit for PDF merging?
The tool works entirely in your browser, so the main limitation is your device's memory. Large files (100MB+) may take longer to process or require more powerful devices. For very large documents, consider splitting them first or using smaller batches.
