Combine PDFs without giving them away
Most online PDF mergers upload your files to their servers, process them there and ask you to trust that they are deleted afterwards. TurboConvert works differently: the merging code is downloaded to your browser and runs on your own device. Nothing is uploaded — you can check it yourself in your browser’s developer tools, under the Network tab.
That makes it a good fit for documents you would rather not share: signed contracts, invoices, payslips, scanned IDs or school applications.
What gets kept when you merge
TurboConvert copies every page as-is into a new PDF:
- Text stays selectable and searchable.
- Images and scans keep their original resolution — no recompression.
- Page sizes and orientation are kept, so you can mix A4, Letter and landscape pages.
- Links inside pages keep working.
Tips for a clean result
- Name your files in order (for example
01-cover.pdf,02-report.pdf) before selecting them — they will appear in that order, which saves reordering. - Mixing scans and digital PDFs? Merge first, then use Compress PDF once on the result to get a lighter file for email.
- Need page numbers across the merged file? Add them afterwards with Add page numbers.
Questions & answers
Is it safe to merge confidential PDFs here?
Yes. The merge runs entirely inside your browser using the open-source pdf-lib library. Your PDFs are never sent to a server, so contracts, bank statements or medical records stay on your device.
Will merging reduce the quality of my PDF?
No. Pages are copied as they are — text stays selectable and images are not recompressed. If you want a smaller file afterwards, run the result through Compress PDF.
How many PDFs can I merge at once?
There is no fixed limit on the number of files. The practical limit is your device's memory; desktop computers routinely handle hundreds of pages.
Can I merge only some pages of a PDF?
Extract the pages you need first with Split PDF, then merge the extracted files. To reorder or delete individual pages, use Organize PDF.
Does it work on iPhone and Android?
Yes. It works in Safari, Chrome, Firefox and Edge on any phone, tablet or computer. Pick files from your Files app or Google Drive and the merged PDF is saved to your downloads.
