Frequently Asked Questions

Is this really free? No hidden costs?
Yes, 100% free forever. No credit card required. No "free trial" that expires. We believe privacy tools should be accessible to everyone.
How is this different from other online PDF tools?
The key difference is privacy. Most online PDF tools require you to upload your files to their servers. LocalKit processes everything in your browser - your files never leave your device. Plus, we're completely free with no limits.
Can I use this for sensitive documents (contracts, NDAs)?
Absolutely. Since all processing happens locally on your device, your confidential documents never touch our servers. We never see your files, period.
What's the maximum file size?
There's no artificial limit. The only constraint is your device's memory. Most computers can easily handle PDFs up to several gigabytes.
Does this work on mobile phones?
Yes! Works perfectly on iPhone, iPad, and Android devices. The interface is fully responsive and touch-optimized.
How can this be free? What's the catch?
No catch. We're building a suite of privacy-first tools. Basic features are free forever. We offer optional Pro features (like batch processing 100+ files) for those who need them, but the core tool remains free.
Can I merge password-protected PDFs?
Yes, as long as you know the password. Simply unlock the PDF first, then merge it with other files.
Will merging PDFs reduce quality?
No. PDFs are merged without any compression or quality loss. Every page is preserved exactly as it appears in the original files.
How many PDFs can I merge at once?
There's no limit on the free version. Merge 2 files or 200 files. For Pro users, batch processing allows 100+ files with advanced options.
Can I reorder pages after merging?
Yes! Before merging, simply drag and drop files to arrange them in your desired order. You can also split the merged PDF later if needed.
Is my data tracked or stored?
No tracking, no storage, no cookies for functionality. We use minimal analytics (Google Analytics) to understand traffic, but your files are never uploaded or logged.
What happens if I close my browser during merging?
Since everything runs locally, closing your browser will stop the process. Simply start over - the merge is very fast anyway.
