Why use local PDF tools?
When you use typical "free online PDF mergers" or "PDF splitters", you are uploading your potentially sensitive documents to a remote server. Even if they claim to delete files after an hour, you are still transmitting data over the internet.
OfflineTools changes this model. By using modern browser technologies (like WebAssembly), we can perform complex PDF manipulations directly on your computer. This means:
- You can process unlimited files without size limits.
- You can work without an internet connection.
- Your bank statements, contracts, and personal ID documents stay safe.
