Good to know before you start
- Pages whose data is genuinely lost cannot be invented — they are skipped.
- A file that is not a PDF at all, or is truncated at the very start, cannot be recovered.
- Everything runs in your browser tab, so the practical size ceiling is your device's memory — a very large document is slower on a phone than on a laptop.
