Frequently Asked Questions
How does PDF merge work?
All processing happens locally in your browser using the pdf-lib library. We never upload your files to any server. The merged PDF is generated in memory and downloaded directly to your device.
Is there a limit on file size or number of files?
No hard limits. Since everything runs in your browser, performance depends on your device's memory. Most modern devices can handle 10+ PDFs totaling several hundred MB.
Can I reorder files before merging?
Yes. After uploading, simply drag any file card up or down to reorder them. The merge order matches the list order from top to bottom.
Is my data safe?
Absolutely. Your files never leave your device. All processing is client-side, and the resulting PDF is generated and downloaded directly from your browser.
