Same merger as the main tool — written for “combine,” not “merge,” if that is the word you searched.

How to combine PDFs

Drop, order, download one file.

  1. 1

    Add PDFs

    Drop two or more PDF files — invoices, scans, or exports.

  2. 2

    Reorder

    Drag files into the order you want. Nothing is sent to a server.

  3. 3

    Download

    Save one merged PDF — free, no watermark, no account.

Private by design

Merge PDF is built to run in your browser. Your documents stay on your device — we do not upload them to our servers or keep a copy of your files.

That is the same privacy model as Filvo image tools: process locally, download, done.

In one sentence

Filvo Merge PDF combines multiple PDFs into one file in the browser. The documents stay on your device.

Filvo vs typical cloud tools

These tools run in the browser. The file is not uploaded to Filvo for the job.

    Studio (next) lets you drag files into the right sequence.

How to combine PDF files

Combining PDFs is lining pages up, not reprinting them.

Drop two or more unlocked files. Drag the stack. Download one PDF. Locked files need to be unlocked first.

Steps

Add the files. Reorder. Download. Split first if you only want some pages from a large pack.

Frequently asked questions

Combining PDFs is lining pages up, not reprinting them.

No. Pages are concatenated in the order you set. Quality does not drop because we copy pages, we do not recompress them.
