Why use Merge PDF on PDF NOVA

Files stay on your device

Processing happens in your browser. Your document is never uploaded to a server, so there is nothing to delete afterwards.

Pick exactly which pages

Use page ranges per file to leave out cover sheets, blank backs or appendices without a separate split step.

Keeps pages intact

Pages are copied as-is, so text stays selectable and vector graphics stay sharp. Nothing is re-rendered or re-compressed.

No sign-up, no watermark

Open the page and start working. Results are clean PDFs with no branding added.

Processing on your device

Merge PDF processes your file in your browser on your device. The file is not uploaded for processing. Download the result to keep a permanent copy. Your active PDF is saved locally in this browser for recovery across refreshes. Close Document removes it; recovery expires after 24 hours and is cleaned up when PDF NOVA next opens. Unsaved changes are not restored.

Frequently asked questions

Is Merge PDF free?

Yes. Merge PDF is free to use without an account and does not add a watermark to your file.

Are my files uploaded anywhere?

No. This tool runs entirely in your web browser using JavaScript and Web Workers. The file is read from your device, processed in memory and saved back to your device.

How many PDFs can I merge at once?

There is no fixed limit. Because merging happens in your browser, the practical limit is your device memory — dozens of typical documents merge in a few seconds.

Can I merge only some pages of each PDF?

Yes. Enter a page range for any file (for example 1-4, 7, 10-12) and only those pages are added to the merged document.

Will merging reduce the quality of my PDFs?

No. Pages are copied without re-rendering, so text, images and fonts are preserved exactly as they were.
