In-Browser vs. Server-Based Tools

|---|---|---|
| Privacy | Files stay on your device and are never transmitted. | Files are uploaded to and processed on a third-party server. |
| Speed | No upload or download wait; speed depends on your device. | Upload and download time grows with file size and connection speed. |
| File size limits | No imposed limit; bounded by your device's memory. | Commonly capped per file or per task, with higher limits on paid plans. |
| Account required | No signup or login. | Often required for larger files or repeated use. |
| Data retention | Nothing to retain; data is cleared from memory. | Files may be stored for a period before deletion. |
