Frequently Asked Questions

01Is it safe to merge sensitive documents?

Yes, absolutely. Unlike other online tools, PDFNations operates entirely client-side. Your files are never uploaded to any server, making it physically impossible for us or anyone else to access them.

02Is there a limit on file size?

No, we do not enforce file size limits. However, if you are merging files for IRCC (Canada Visa) or UPSC (India) uploads, remember these portals have strict limits (4MB and 300KB respectively). You may need to use our Compression tool after merging.

03Can I merge PDFs on my phone?

Yes! Our tool works perfectly on all modern browsers, including mobile devices like iPhones (iOS) and Android phones.

04Do I need to install any software?

No installation is required. Everything runs in your web browser, compatible with Chrome, Firefox, Edge, and Safari.
