What this does

Merge PDF combines multiple PDF files into a single document, keeping the order you specify. It's the fastest way to turn a stack of separate PDFs into one clean file ready for email, archiving, or printing.

When to use it

  • Consolidating chapters of a report into one document
  • Joining receipts or invoices before submitting an expense report
  • Combining signed contracts with their addenda
  • Bundling resume + cover letter + portfolio into a single attachment

Frequently asked

Will my PDFs be uploaded to a server?

No. Uvelia runs the merge entirely in your browser using WebAssembly. Your files never leave your device.

Is there a limit on how many PDFs I can merge?

Free accounts can merge up to 5 files at once with each file under 50 MB. Pro lifts both limits.

Will the merged file lose formatting, fonts, or images?

No. The page content of each source PDF is copied byte-for-byte. The original quality is preserved.
