Does merging reduce quality?

No. Merging copies the original pages across untouched — the same fonts, images and resolution. The result is exactly as sharp as the source files.

Is the Merge PDF tool free?

Yes — it's free with no sign-up, no watermark added to your file, and no daily limit. Files are processed on demand and never stored on our servers.

Merge PDF

Combine up to 20 PDFs into a single document. Drag the files into the order you want before merging — the page order in the result matches the order on screen.
