Merge PDF — FAQ
How do I merge PDF files?
Add two or more PDFs above, reorder them with the arrows if needed, then press Merge. FileTinker combines them in your browser and gives you a single PDF to download.
Are my PDF files uploaded anywhere?
No. Merging happens entirely in your browser — your files never leave your device and nothing is stored on a server.
Is there a limit on the number or size of PDFs?
There is no fixed limit, but very large files use your device's memory since everything runs locally. Most everyday documents merge instantly.
Will merging change the quality of my PDFs?
No. Pages are copied as-is into the new document, so text and images keep their original quality.
