About Safe Viewer

Safe Viewer is a browser security tool for previewing supported files in a safer read-only way. It is designed to reduce risky clicks and limit active content where possible.

How to use Safe Viewer

Open the desktop version, choose the supported file you want to preview, and review the content inside the safer viewer rather than opening the file normally. Use caution with any suspicious document.

Who Safe Viewer is for

For people who want to inspect the content of a supported file before deciding what to do with it. It suits cautious review of text, exported data and simple images.

What you can use Safe Viewer for

Safe Viewer can be useful for checking unknown text files, exported data, screenshots, simple images, and suspicious documents where you want a safer first look before deciding what to do next.

Features

  • Selection of a supported file for preview.
  • Read-only viewing of content.
  • A focus on text and image previews with active content limited where possible.

Tips for using Safe Viewer

Check which formats the viewer supports before choosing a file. Read the preview without following unfamiliar links, and do not interpret a normal-looking display as proof that the original file is safe.

Important warnings and limitations

A read-only preview is not proof that a file is harmless or fully sanitised. Unsupported content may not be shown, and the preview does not establish that the original is safe to open in another application.

Data handling and privacy

Review the instructions before entering, uploading, copying, or storing information. Do not use passwords, private keys, recovery phrases, payment details, or other highly sensitive data unless you understand exactly how the tool handles it.

Safe Viewer FAQ

Does Safe Viewer make every file safe?

No. It is intended to reduce risk by previewing content more safely, but it cannot guarantee that every file is harmless.

What file types are safest to preview?

Plain text-style exports such as TXT, CSV, or JSON are usually simpler to inspect than complex document formats.
