Chrome sometimes blocks downloads it considers risky, and the warning looks alarming: "This file is dangerous" or a blocked download in the toolbar. Usually it is Chrome's Safe Browsing being cautious, not proof the file is malicious. Here is how to tell which case you are in.
Chrome's Safe Browsing checks every download against lists of known-dangerous sites and files, and it also flags downloads heuristically: files from sites it has not seen before, files that ask for elevated permissions, and file types commonly abused by malware. A plain MP3 converter site the browser has never encountered can trip the heuristic even though the MP3 itself is harmless.
To keep it: click the blocked download in the toolbar (or the downloads list), click the three dots, and choose Keep.
If the download is blocked but everything else converts fine, work through our converter troubleshooting guide. Converting on a computer? See the Windows conversion guide for device-specific steps.
Chrome's Safe Browsing blocks or warns about downloads that look risky: unfamiliar sites, permission-requesting files, and file types abused by malware. Legitimate downloads from lesser-known sites get flagged automatically.
Only when you expected it: you clicked it yourself on a site you trust, and the file type matches (an MP3 you converted, for example). Never keep an unexpected executable.
MP3s are harmless audio, but Chrome can flag downloads from sites it has not seen before. If you converted the link yourself and the blocked file is an .mp3 with the expected title, keeping it is safe.
Yes. School and work administrators can set Chrome policies that block all downloads with no user override. On a managed device, use the browser-only conversion approach.
