Is the merge PDF tool free to use?

Yes. It’s free and runs in your browser - no signup, no install.

How many PDFs can I merge at once?

There’s no hard limit for typical use. You can queue many files; very large batches may feel slower depending on your device.

Yes. Drag each file in the list to set the order, and optionally pick a page range per file (for example, 1-3, 5).

No. The tool joins the files as-is. Bookmarks and internal links are preserved when the source PDF supports them.

Run the result through the PDF compressor. It keeps readable quality while cutting file size - useful before emailing or uploading.

Merging runs in your browser. Files are processed locally and not stored on our servers.
