Preguntas frecuentes
Are my files uploaded to a server?
No. PDF processing happens locally in your browser with pdf-lib, so your files never leave your device and nothing is stored.
Can I reorder the files?
Yes. Use the up and down buttons on each file to set the order before merging.
Is there a file limit?
No artificial limit — merging happens in your browser, so very large files are only limited by your device's memory.
Is it really free?
Yes — free, with no signup, no watermark and no limits.
