常见问题

Is there a limit to how many PDFs I can merge?

There's no hard limit, but very large merges (50+ files or hundreds of MB) may slow down depending on your device's memory.

Does merging preserve bookmarks and links?

The tool preserves page content and formatting. Internal bookmarks and hyperlinks may not be preserved in all cases.

Can I reorder the PDFs before merging?

Currently, PDFs are merged in the order they appear in the file list. Upload them in your desired order, or remove and re-add files.
