Validate
The browser checks the selected file type, size, count, and tool-specific constraints before processing starts.
- 03
Process locally
Implemented local engines read the selected bytes in the browser. Progress reflects actual work where the engine can report it.
- 04
Review and download
Inspect the result, copy or download it where supported, then clear the workspace or process another file.
Local means an implemented supported operation runs in the browser using the selected file. It does not mean the entire session is offline. The privacy boundary, OCR, and PDF-text limits are documented in the local processing guide.
