Common Mistakes to Avoid

Using unoptimized or damaged source files that trigger parse errors.
Exceeding single-file memory quotas by uploading multi-gigabyte files.
Ignoring configuration presets suited to specific platform requirements.

Troubleshooting & Common Issues

Processing fails or browser tab becomes unresponsive

Possible Cause: Very large files can exhaust available browser tab heap memory during heavy graphics or media decoding.

Solution: Close unused browser tabs, or process files in smaller batches (e.g. 5-10 files at a time instead of 30).

Output format or file extension does not open in third-party viewer

Possible Cause: Certain legacy desktop applications lack codecs for modern formats like WebP, AVIF, or Opus.

Solution: Select standard backwards-compatible export formats like PNG, JPG, or MP3 in the tool settings dropdown.

Quality appears different from expected output

Possible Cause: Aggressive lossy compression or incorrect aspect ratio scaling settings selected in the interface.

Solution: Adjust the quality slider to 85%+ or choose lossless processing mode to retain original fidelity.

Client-Side Processing: Energy Converter runs entirely in your browser memory via HTML5 Canvas / WebAssembly. Your files and data are never transmitted or stored on any remote server.
