Convert MP4 to OGG Free

The catch with most "free" converters shows up at the end: the download needs an account, a watermark tone is mixed into the audio, or your file waits in a queue behind paying users. None of that applies here. The engine is the same one Pro uses — same speed, same bitrate options — and the output is clean and unmarked.

Free also means free of the usual hidden cost: your file. Many no-cost converters are free precisely because your upload is the product. Here the conversion runs in your browser, so the MP4 never leaves your device. Given that MP4 files usually come from phone video, recorded webinars and lectures, downloaded clips, and screen captures, that's worth more than the price.

Expect roughly 50× smaller: MP4 runs about 60 MB per minute, OGG about 1.2. Both MP4 and OGG are lossy, so this is a second-generation encode — it can't add anything back. Use 192 kbps or above and the extra loss stays inaudible.

Free covers input files up to 20MB file size limit with a 10-second preview output, and 5 conversions per month. Pro removes those limits for full-length conversions up to 500MB file size limit — and the privacy behaviour is identical, because there was never a server in the loop.

MP4 files come from phone video, recorded webinars and lectures, downloaded clips, and screen captures. The video stream is nearly the entire file, so extracting the audio collapses a 500 MB video into a few MB — which is the whole reason this conversion exists. OGG is the destination because it plays essentially everywhere — game assets and every ordinary phone, browser, and player. Expect roughly 50× smaller: MP4 runs about 60 MB per minute, OGG about 1.2. Both MP4 and OGG are lossy, so this pair stacks a second encode — at a generous bitrate it stays inaudible, but if a lossless original of the MP4 exists, encode the OGG from that instead.
