Merge PDF files into one document – and sign right away

A contract and its annexes, an offer and a specification, multi-page scans – they often need to be submitted as one document with one signature. The Tvarka PDF merge wizard does that in a few clicks.

How it works

  1. You upload several files – PDF and .docx both work (text documents are converted automatically).
  2. You arrange them in the order you want.
  3. You get one PDF – you can send it for signing with a qualified electronic signature (QES) right away or save it in the archival PDF/A format.

Limits: one file – up to 50 MB, one merge job – up to 150 MB.

How is this different from random "merge PDF" websites?

  • Your documents do not travel who knows where. Merging happens on Tvarka infrastructure in the European Union; access is limited to you and the people the Manager has authorized.
  • The result can be signed right away. No downloading, carrying to another system and uploading again – you merge and invite to sign.
  • Version history. You see what the document was built from and what changed.

Frequently asked questions

Can .docx and PDF be merged together?

Yes – .docx files are automatically converted to PDF before merging, so you can mix formats in one job.

Does merging cost anything?

No – the wizard costs nothing. You pay only for successful qualified signings according to the pricing; merging and downloading are free of charge.

Will the document quality be preserved?

Yes – pages are carried over without recompression, and you can save the final document in the archival PDF/A format for long-term storage.

You reach the wizard after signing in with your electronic signature – this keeps your documents accessible only to users with access rights.
