MP3 to AV1 Conversion FAQ
Is the MP3 to AV1 converter free?
+
Yes. One conversion an hour is free, with no account needed, for a file within the free size limit. A paid plan removes the hourly limit and the size limit, and lets you add several files to one job.
How big an MP3 file can I convert to AV1?
+
Free conversions have a size limit per file, set by the type of file, and the page tells you when a file is over it. A paid plan removes that limit, so much larger files can be converted.
Can I convert many MP3 files to AV1 at once?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Does the MP3 to AV1 converter work on phones / tablets?
+
Yes — the UI is responsive and the conversion pipeline runs server-side, so mobile devices upload-then-download just like desktops. iOS and Android browser file pickers (camera roll, Files app) work end-to-end without an app.
Which browsers does the MP3 to AV1 converter support?
+
Chrome, Firefox, Safari (15+), Edge, and Opera. The converter uses a plain `<input type="file">` upload — no WebAssembly or PWA dependencies — so even older browsers convert MP3 to AV1 successfully.
Are my MP3 files kept private?
+
Yes. Uploaded MP3 files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted AV1 are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy. Nothing beats MP3 for compatibility — car stereos, gym equipment, DAPs and twenty-year-old hardware all read it without question.
What if the AV1 download does not start automatically?
+
Disable any pop-up blocker, then click the download button manually. The result link stays active for 24 hours, so if your network fails mid-download you can re-trigger from the result page without re-uploading the MP3.
How long does MP3 to AV1 conversion take?
+
It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame. AV1 delivers roughly 30% better compression than H.264 at the same quality and carries no licence fees, which is why YouTube and Netflix push it. AV1 encoding is slow, and hardware decoders only appeared in phones and TVs from about 2020 onward — older devices fall back to power-hungry software decoding.
Do I need to install software to convert MP3 to AV1?
+
No — the converter runs entirely in your browser plus our servers. No desktop install, no plugin, no extension. Just upload your MP3, wait, download the AV1.
Can I convert MP3 to AV1 without an account?
+
Yes for one-off conversions. Sign up free for batch history, server-side file storage, and higher conversion limits. Premium adds parallel workers, bigger file caps, and removes ads.
