Frequently Asked Questions
Yes, absolutely. Our tool runs entirely in your browser using JavaScript. Your files are never uploaded to our servers, meaning they stay on your device at all times.
There is no hard limit on the number of files. However, merging very large files (e.g., hundreds of megabytes) may depend on your device's available memory since all processing happens locally.
You can reorder the files themselves before merging. To reorder individual pages within a single PDF, you might need to use our Split tool first to extract the pages and then merge them in your preferred sequence.
No. Our PDF merger preserves the original quality, fonts, and images of your documents. We simply join the content streams together without re-compressing them unless you specifically use a compressor tool later.
Yes! FluxToolkit is fully responsive. You can merge PDFs on your iPhone, iPad, or Android device directly through your mobile browser.
