PDF Merger - Frequently Asked Questions
Is there a limit to how many PDFs I can merge?
You can merge up to 50 PDF files at once with a combined total size of 500MB. For larger batches, merge in groups. Each page from every PDF will be included in the final merged file.
Can I rearrange the order of PDFs before merging?
Yes! After uploading, simply drag and drop the PDF thumbnails to reorder them. The final merged file will maintain the order you specify. You can also remove individual files before merging.
Will the merged PDF maintain quality and formatting?
Absolutely. Our merger preserves the exact quality, formatting, fonts, and layout of each original PDF. No compression or re-encoding occurs - pages are simply combined in sequence.
Can I add a table of contents to the merged PDF?
The basic merger combines files as-is. For advanced features like automatic table of contents, page numbering, or bookmarks, use our PDF Editor tool after merging.
