# Frequently Asked Questions

How many PDFs can I merge at once?▼
There's no hard limit. You can merge as many PDFs as your browser's memory can handle, typically dozens of documents without issues.
Will merging reduce PDF quality?▼
No. We copy pages directly from source PDFs without re-rendering, so the merged PDF maintains 100% of the original quality.
Can I change the order of documents?▼
Yes! Simply drag and drop documents to reorder them. The order you arrange them is the order they'll appear in the merged PDF.
What happens to bookmarks and links?▼
Basic page content is preserved. However, interactive elements like bookmarks may not transfer depending on PDF complexity.
Is there a file size limit?▼
No server upload limits! The only constraint is your device's available memory, so you can merge even very large PDFs.
