Questions & Answers

Is Seleniun secure?

Yes. Your files are handled only in secure temporary folders on our server and are automatically deleted as soon as the task finishes.

Do you use my documents to train models?

No. We never use your files to train AI models. For AI features, we send only the extracted text over HTTPS to the configured provider.

What formats are supported today?

We currently support PDF to DOCX conversion, plus PDF utilities such as compression, merging, splitting, encryption, and summarization.

Are AI tools available now?

Yes. PDF summarization is available with different modes. If the AI service is unavailable, we run an offline fallback summarizer.

Do you keep my files after processing?

No. Files exist only during the job in a temporary workspace and are permanently deleted right after.

What are the current limits?

For AI summarization, the limit is 10 MB or 15 pages per file. For other tools, we support files up to around 100 MB.

How does file security work?

Each operation runs in an isolated temporary workspace. Files are securely removed after use.
