Frequently Asked Questions

How many PDF files can I merge at once?
You can merge as many PDF files as needed in a single session. Select all files at once using your file browser for the fastest experience.

Does the order of files matter when merging?
Yes. PDFs are merged in the order they appear in the file selection. Select your files in the desired order, or rename them with numbers (e.g., 01_intro.pdf, 02_chapter.pdf) before selecting.

Will the merged PDF retain bookmarks and hyperlinks?
Our merger preserves the core content, layout, and text. Complex interactive elements like bookmarks may vary depending on the original files.

Can I merge password-protected PDFs?
Currently, our tool works with unlocked PDF files. If your PDF is password-protected, you will need to remove the password first.

Is there a file size limit for merging?
Free users can merge PDFs up to the server's processing limit. For best results, compress large PDFs first using our PDF Compressor.
