What is the Tools69 Universal File Viewer?

The Tools69 Universal File Viewer is a versatile tool that automatically detects your file type and opens it in the appropriate viewer or editor, all directly in your browser without installing specialized software.

How do I use the Universal File Viewer?

Upload your file using the upload button or drag and drop it. The tool will detect the file type automatically and open the appropriate viewer or editor. Depending on the file type, you can view, edit, and download the modified file.

Are my files uploaded to your servers?

It depends on the file type. Formats like PDF, XLSX, CSV, JSON, XML, TXT, images, etc are processed entirely in your browser, so your data never leaves your device. Some document formats such as DOC, DOCX, PPT, PPTX, ODT, RTF, etc cannot be rendered directly by the browser, so they are temporarily uploaded to our server for conversion and automatically deleted after 24 hours.

Is the File Viewer free?

Yes. The tool is completely free and does not require registration.

What file formats are supported?

The viewer supports multiple common file formats including PDF, JSON, XML, CSV, TXT, RTF, LOG, ODT, and other text-based formats.

Is there a file size limit?

It depends on the file type. Document formats that require server-side conversion (such as DOC, PPT, and XLS) have a 70 MB file size limit. All other file types are processed entirely in your browser with no fixed size limit — the maximum depends on your device's available memory.
