Smallpdf alternative that never uploads your files
Smallpdf is a popular and polished online PDF suite. Like most online PDF services, it processes documents on its servers, so your file is uploaded first. Lockpage does the same jobs inside your browser tab: contracts, medical records and IDs stay on your computer.
| Smallpdf | Lockpage | |
|---|---|---|
| Where your file is processed | On Smallpdf's servers (the file is uploaded) | In your browser — the file never leaves your device |

| Account required to start | Often for advanced tools | No — 2 free documents a day without sign-up |
| Signature requests by link | Varies by plan | Yes, end-to-end encrypted link |
| OCR, compare, Bates numbering, PDF/A | Partly, varies by plan | Yes (Pro) |
| AI summary, chat, translation | Varies | Yes — only extracted text is sent, never the PDF |
| Interface languages | Many | English, Español, Français, Deutsch, Русский |

When to choose Lockpage
Choose Lockpage when the document is confidential — contracts, HR files, patient records, IDs — or when your company doesn't allow uploading files to third-party services.
