Merge PDF files in your browser, without uploading them

Open your first PDF below, then add more files from the Pages panel. You can drag pages into a new order, delete the ones you do not need, and save the result as one PDF. The files are combined on your device, not on a server.

You can also export just the pages you select as a separate file.

Your PDF is processed on this device and never uploaded.

How it works

  1. Open the first PDF with the Open button, or drop it on the tool.

  2. Click Pages in the toolbar to show the page thumbnails.

  3. Click the + (Add file) button at the top of the panel and choose one or more PDFs. Their pages are added after the current page.

  4. Drag thumbnails to reorder. To remove pages, select them, open Manage and choose Delete.

  5. Click Save a copy to download the combined PDF.

Questions

Plain answers

What this tool does, and what it does not.

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

There is no file count limit, but the combined PDF must stay under 100 MB, and very large documents depend on how much memory your device has.

Why was a file rejected when I tried to combine it?

If two PDFs contain form fields with the same name, Quire refuses to combine them, because the merged form would mix up their values. Merge one of them after flattening it in another tool, or combine forms that use different field names.

Can I copy or duplicate pages?

Not in this version. Copy, cut and paste of pages are switched off. You can reorder, delete, add from another file and export selected pages.

Is my PDF uploaded anywhere?

No. The page and its PDF engine (Mozilla’s PDF.js) load from quireapps.com, and after that your file is opened, edited and saved inside your browser tab. The file is never sent to a server, and there is no analytics or tracking on this page. You can check this yourself in your browser’s developer tools under Network.

Is it free? Do I need an account?

It is free, with no account, no sign-up, no watermark and no daily limit. Files can be up to 100 MB.

Which browsers does it work in?

It is tested in Chromium-based browsers such as Chrome and Edge. It is built on PDF.js, which also runs in current Firefox and Safari, but those have had less testing here. In Chrome and Edge, Save a copy lets you pick where the file goes; in other browsers it downloads.
