🔒 100% Client-Side Privacy: Your files never leave your browser.

Five attachments get lost. One file is easier to send — compress after if the inbox still says no.

How to make one attachment

Combine first. Compress only if the inbox still refuses.

  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 PDFs for email

One attachment beats a pile of files.

This page is the merger aimed at sending. After you combine, open the compressor if the mailbox still refuses the size.

Steps

Drop the files. Order them. Download. Compress if needed. Do not merge locked PDFs.

Frequently asked questions

One attachment beats a pile of files.
