How do I combine multiple PDFs into one without losing quality?

PDF Legacy merges PDFs at original resolution. Unlike compression-based mergers, our tool concatenates files without re-rendering pages, preserving embedded fonts, vector graphics, and image quality.

Is there a limit to how many PDFs I can merge for free?

No strict limit on the free tier. You can merge 2 PDFs or 50 PDFs into one document. The only constraint is your browser's memory — very large batches may require splitting into smaller groups.

Can I rearrange pages before merging PDFs?

Yes. PDF Legacy's Organize PDF tool lets you reorder pages via drag-and-drop before merging. Combine Organize + Merge for full control over your final document structure.

Will hyperlinks and bookmarks work after merging PDFs?

PDF Legacy preserves internal hyperlinks, bookmarks, and table of contents entries during merging. External URLs remain clickable in the combined output.

How do I merge PDFs without uploading to a server?

PDF Legacy processes merges 100% locally in your browser. Files never touch external servers — ideal for merging confidential contracts, medical records, or legal documents privately.
