Is there a limit on the number or size of files I can merge?

Because all processing happens on your computer, the main limitation is your browser's memory. For best performance, we recommend working with a reasonable number of files (e.g., up to 20-30 at a time) and avoiding extremely large individual PDFs (over 100MB).

Will the quality of my PDFs be affected?

No. The merging process does not re-compress or alter the original quality of your PDF pages. The content, images, and formatting of each page will be preserved exactly as they were in the original files.
