Security & File Protection
All PDF data remains exclusively in your browser runtime. No files are transmitted to external servers, stored in cloud databases, or processed on remote machines. When you close the browser tab, all temporary data is permanently cleared from browser memory. We collect zero logs about your file operations or document content.
Privacy & Data Policy
We store no cookies, no usage analytics, and no information about files you upload or merge. Your PDFs are never transmitted over networks, saved to disk, or analyzed by any external service. Full client-side processing ensures complete anonymity. Simply close your browser tab and all traces are gone—nothing is retained on our servers because processing never involves our servers.
Tips
- Arrange files in your preferred order before clicking Merge—they combine in selection order
- Test with 2-3 files first if you have concerns about file compatibility
- Use a modern browser (Chrome, Firefox, Edge) for best performance with large files
- If merging fails, check that none of the PDFs are password-protected or corrupted
- Download immediately after merging—the file only exists during that browser session
Frequently asked questions
Are my PDF files uploaded to a server?
No. All PDF merging happens entirely inside your browser using client-side processing. Your files are never sent to any external server or stored anywhere except in your browser's temporary memory.
Can I merge password-protected PDFs?
The tool attempts to handle encrypted PDFs, but some password-protected documents may fail. Remove password protection from your PDFs first if possible.
Does the merge preserve PDF formatting?
Yes, all text, images, colors, fonts, and page layouts are preserved exactly as they appear in the original files.
Can I merge hundreds of PDFs at once?
Technically yes, but browser memory limits apply. Most modern browsers can handle dozens of files smoothly. Very large batch merges (100+ files) may require more powerful devices.
Can I control the order pages appear in the merged file?
Yes—files merge in the order you select them. Select file 1 first, then file 2, and file 1's pages will appear before file 2's pages.
Do I need to create an account?
No account or email is required. Use the tool instantly and completely anonymously.
Does this tool work on mobile devices?
Yes, it works on modern iOS and Android browsers, though merging very large PDFs may be slower on mobile devices with limited RAM.
