Upload your MP4 file using the picker above and the converter detects the source type and runs the MP4 → AV1 pipeline. The result downloads automatically when conversion completes; no account needed for one-off conversions.
Is the MP4 to AV1 converter free?
+
Yes — basic MP4 → AV1 conversion is free with no registration required. Premium adds higher per-file size limits, more parallel batch workers, longer retention, and removes ads.
How big a MP4 file can I convert to AV1?
+
Free accounts: up to 100 MB per MP4 file. Premium: typically 1 GB per file depending on the source type. Very large files are split into chunks server-side when the AV1 format allows.
Will conversion change the content of my MP4?
+
Conversion preserves all information that both MP4 and AV1 can represent. Format-specific features the AV1 cannot represent (e.g. vector data in raster output, formulas in plain-text output) are rasterized or stripped — the result page lists what changed.
Can I convert many MP4 files to AV1 at once?
+
Yes — drop multiple MP4 files into the upload zone and they are queued in parallel. Premium runs more parallel workers; on a 50-file batch this is the difference between minutes and seconds.
Does the MP4 to AV1 converter work on phones and 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.
Which browsers does the converter support?
+
Chrome, Firefox, Safari (15+), Edge, and Opera. The converter uses standard `<input type="file">` upload — no WebAssembly or PWA dependency — so even older browsers work to upload a MP4 and download the AV1.
Are my MP4 files kept private?
+
Yes — uploaded MP4 files are processed in isolated workers and deleted within minutes. We never view, retain, or share content. The retention window is at /privacy/.
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 drops mid-download you can retry from the result page without re-uploading the MP4.
How long does MP4 to AV1 conversion take?
+
Typically seconds for small files, a minute or two for files near the size cap. The server-side pipeline runs on dedicated workers — your laptop CPU is not the bottleneck and a slow phone uploads at exactly the same conversion speed as a fast desktop.
Do I need to install software to convert MP4 to AV1?
+
No — the converter runs entirely in your browser plus our servers. No desktop install, no plugin, no browser extension. Just upload, wait briefly, download the AV1.
Can I convert MP4 to AV1 without creating 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, longer result retention, and no ads.
