- What video formats can I convert to MP4?
- Nearly everything — MKV, MOV, AVI, WebM, FLV, OGG, TS, 3GP, WMV, and more. If your browser can read the file, this tool can convert it to MP4.
- Will converting to MP4 reduce quality?
- With the High quality preset the loss is negligible. MP4 with H.264 encoding is extremely efficient, so files are often smaller than the original with almost identical visual quality.
- Is there a file size limit?
- Browser processing comfortably handles files up to about 2 GB — your device's memory is the practical limit. On a paid plan, bigger files process on our servers instead: up to 20 GB on Pro and 50 GB on Business.
- Do I need to install any software?
- No. The converter runs entirely in your browser using FFmpeg WebAssembly. There is nothing to download or install.
- Can I convert multiple files at once?
- Yes. Use the batch mode to queue multiple files and convert them all to MP4 in one session.
- Why choose MP4 over other formats?
- MP4 with H.264 is the most universally supported video format. It plays on every phone, tablet, desktop, smart TV, and social media platform without extra codecs or plugins.
