Online Audio Converter

Online Audio Converter is a straightforward, no-install tool that excels at one job: converting audio files and pulling audio from video, all in your browser. It's part of the 123apps suite, which includes video, PDF, and image tools, and the same subscription covers all 51 apps. The interface is clean and simple: upload a file (drag-and-drop works), pick an output format, adjust quality if you like, and hit convert. You can tweak bitrate, sample rate, channel count, and even apply effects like fade in/out, reverse, and voice removal—features you usually find in desktop editors. Batch conversion is a big plus: you can process multiple files at once and download them as a ZIP, saving time. Privacy is a genuine strength. Files are automatically deleted from their servers a few hours after processing, and you don't need to create an account for basic use. That's a real differentiator for users who don't want their audio stored indefinitely. The biggest limitations are the free-tier caps: 70 files per day and 4 GB per file. For casual use this is plenty, but heavy users—podcasters, video editors, or anyone doing daily batch conversions—will hit the wall quickly. Premium removes those limits, bumps the cap to 10 GB, adds AI audio processing, removes ads, and speeds up conversions. At around $6/month (or $48/year), it's reasonably priced, especially since it covers all 123apps tools. Where it falls short: no offline mode (it's web-only), no advanced editing suite (you can't trim, splice, or apply heavy EQ), and no long-term storage—you have to download your files and manage them yourself. Professional audio engineers will still prefer Audacity or Adobe Audition. But for everyday conversions, ringtone creation, or pulling audio from video, Online Audio Converter is a solid, free choice.
