Frequently Asked Questions

How many PDFs can I merge at once?

There is no hard limit on the number of files. You can merge as many PDFs as your browser can handle. Processing happens locally in your browser, so performance depends on your device.

Will merging change the quality of my PDFs?

No. The merge tool combines your PDF pages without re-encoding or compressing them. Text, images, and formatting remain exactly as they are in the original files.

Is there a file size limit?

No upload limit. Files are processed in your browser, not on a server. Larger files may take a moment longer to process, but there are no restrictions.

Is this tool really free?

Yes, the PDF merger is completely free with no restrictions. For document creation, e-signatures, and AI-powered tools, Writ (QuikDB) offers a lifetime plan at $29.99.
