Frequently Asked Questions

Can I change the order of documents before merging them?
Yes. Simply drag and drop the document cards into your preferred sequence before clicking Merge. The combined file will follow your exact customized order from first page to last without any discrepancies.
Will merging affect the quality of images or vector text in my PDFs?
No. Our merging engine performs lossless concatenation of PDF object streams. All text formatting, vector paths, high-resolution graphics, and hyperlinks are preserved exactly as they appeared in the original source files.
Is there a limit to how many PDF files I can merge at once?
There are no artificial limits. You can merge dozens of PDF documents simultaneously, constrained only by your device memory, completely free without registering an account or entering personal payment details.
Does OmegaTools store or view my merged PDF documents?
Never. Your PDF files remain strictly within your browser local sandbox. No data, text, or images are transmitted across the internet, logged in databases, or stored on remote cloud servers.
Can I merge password-protected PDF files directly?
If any document is password-protected, use our Unlock PDF tool first to remove security restrictions before merging, as encrypted files cannot be assembled in-browser without prior authorization.
