Merge PDF files
Combine several PDFs into a single document without uploading anything. Add your files, drag them into the order you want, and FileTinker merges them in your browser — your files never leave your device.
How to merge PDF files
- Add two or more PDFs above by dropping them in or tapping to browse. Nothing uploads — each file is read straight into your browser.
- Drag the files, or use the arrows, to set the order in which they should appear in the combined document.
- Press Merge, then download the single PDF. Pages are copied as-is, so text and images keep their original quality.
About merging PDFs
Merging joins several PDFs end to end into one document, in whatever order you arrange them. FileTinker copies each page exactly as it is into the new file, so text stays selectable and images keep their original resolution — nothing is re-compressed or downgraded.
This is handy for combining a cover letter and CV, stitching scanned chapters together, or bundling receipts into a single attachment. Everything runs in your browser, so even confidential contracts and statements never touch a server. There is no fixed limit on file count or size, though very large documents use your device's own memory since the work happens locally.
Frequently asked questions
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.
