What is the Tools69 LOG Viewer?

The Tools69 LOG Viewer is a browser-based tool that lets you open and inspect log files with line numbers and a built-in search feature, without using specialized log analysis software.

How do I view a LOG file?

Upload your .log file or drag it into the viewer. The log file will open instantly with line numbers. Use the search bar to find specific text — the tool highlights all matches and lets you navigate between them with previous/next buttons.

Are log files uploaded to your servers?

No. Log files are processed locally in your browser, meaning the data stays on your device and is never transmitted or stored.

Is the LOG Viewer free?

Yes. The tool is completely free and can be used without registration.

A LOG file records events generated by software systems, servers, or applications and is commonly used for debugging and monitoring.

Is there a file size limit?

There is no fixed file size limit. Since all processing happens directly in your browser, the maximum file size depends on your device's available memory and browser capabilities. Most modern devices handle large files without any issues.
