Frequently Asked Questions
How many PDF files can I merge at once?
You can merge multiple PDF files simultaneously with no strict limit. However, for optimal performance, we recommend merging up to 20 files at once. Larger batches may take longer to process depending on file sizes and your device's capabilities.
Does merging PDFs reduce quality or file size?
No, our PDF merger preserves the original quality and resolution of all pages. The merged file contains all original content without compression or quality loss. The final file size will be approximately the sum of all input files.
Can I change the order of pages before merging?
Yes, you can drag and drop files to reorder them before merging. The files will be merged in the exact order you arrange them. Make sure to review the order carefully before clicking merge to ensure your final document flows correctly.
Are bookmarks and links preserved when merging PDFs?
Yes, internal bookmarks, hyperlinks, and table of contents are preserved during the merge process. However, page references may be updated to reflect the new page numbers in the merged document. External links remain functional.
Is it safe to merge confidential or sensitive PDFs?
Absolutely. All PDF processing happens entirely in your browser - no files are uploaded to our servers. Your documents never leave your device, ensuring complete privacy and security for confidential materials. Files are automatically cleared from memory after processing.
What should I do if the merge fails or produces errors?
Common solutions include: checking that all files are valid PDFs, removing password protection from protected PDFs, ensuring files aren't corrupted, and trying with smaller file sizes. If problems persist, try merging fewer files at once or refresh the page and try again.
