Why this site exists

Media formats often fail for reasons that are difficult to diagnose: expired HLS tokens, CORS restrictions, unsupported codecs, legacy Flash content, or image formats Windows cannot preview by default. These tools focus on a clear result and a useful explanation instead of hiding errors.

Privacy by design

HEIC and local SWF files are processed inside your browser. M3U8 playback necessarily requests the stream from the URL you provide; the remote stream host may receive normal browser network information when those requests are made.

Browser-based tools built for real troubleshooting

WebMediaBench focuses on media problems users actually need to solve: HLS playback failures, HEIC compatibility and legacy SWF files. The goal is not just to open a file, but to expose useful clues when something fails.

Why diagnostics matter

A media URL can fail because of CORS, expired tokens, HTTP 403/404, mixed content, unsupported codecs or missing external assets. Useful tools should surface those clues instead of showing only “playback failed”.
