Is it safe to merge my PDFs here?

Yes, absolutely. All PDF processing happens directly in your browser. Your files are never uploaded to our servers, ensuring your data remains private and secure.

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

For best performance, we recommend combining up to 10 files at once, with each file being no larger than 50MB. The tool works entirely in your browser, so performance depends on your computer's capabilities.

Will the quality of my PDFs be affected?

No, our tool merges your PDF files without re-compressing them, so the original quality of your text and images is fully preserved in the final document.
