Browser-based vs cloud upload
Many PDF websites upload your file to their server. ToolsWebPro PDF and photo tools run in your browser using JavaScript — files stay on your device during conversion unless you explicitly use a server feature (like video download APIs).
What leaves your device
- PDF merge/split in browser — stays local.
- Photo resize/convert — stays local.
- Social downloaders — only the public URL is sent to our API to fetch media.
- Encrypted chat — ciphertext only; we never see message text.
