  • Q: What file formats are supported?
    A: We support common office and image formats, including .docx, .pdf, .xlsx, .xls, .pptx, .jpg, .png, .webp, .bmp, and more. For best results, use standard format files. If you encounter issues, refer to the tool page instructions.
  • Q: How many files can I upload at once?

  • Q: Will the converted PDF retain the original Excel formatting?
    A: Yes, FirstDoc ensures that tables, fonts, and layouts in Excel files are preserved as much as possible during PDF conversion. For complex macros or dynamic charts, check the file content before uploading. For formatting issues, contact firstdoc.top@gmail.com.
  • Q: Are the tools supported on mobile devices?
    A: Yes, FirstDoc is fully compatible with mobile browsers (e.g., Chrome, Safari) without requiring an app. For the best experience, use the latest browser version.

🔒 Data Privacy & Security

We are committed to protecting your privacy and data security. All file processing adheres to strict security standards.

  • Q: Are uploaded files saved or used for other purposes?
    A: No. Your files are only used for processing during the current session and are deleted from the server immediately after completion. We do not store, view, or analyze file content, and data transmission is encrypted via HTTPS (TLS 1.3) for security. See our Privacy Policy for details.
  • Q: Do files need to be uploaded to a server?
    A: Most operations are performed in your browser. For server-side processing (e.g., large file compression), data is transmitted via HTTPS encryption and deleted immediately after processing, with no retention.
  • Q: Are there file size limits?
    A: Single files can be up to 50MB, with a total limit of 100MB. We recommend compressing large files or splitting them into smaller ones. For oversized files, contact firstdoc.top@gmail.com.

📊 Ads & Commercial Use

  • Q: Why does the website display ads?
    A: To keep our tools free forever, we rely on the Google advertising system to support operations. Ad content is provided by Google and is unrelated to your file content, ensuring your privacy is unaffected.
  • Q: Can the tools be used for commercial purposes?
    A: FirstDoc tools are free to use, but ensure that processed files do not infringe on copyrights or privacy. Users are responsible for the legality of file content. See our Terms of Service for details.

📬 Contact & Feedback

  • Q: What should I do if the conversion fails or errors occur?
    A: If a conversion fails, it may be due to unsupported file formats, file corruption, or network issues. Ensure the file is in .xlsx/.xls format and the network is stable, then try again. If the issue persists, send a screenshot of the problem to firstdoc.top@gmail.com.
