Common conversions

What people convert to MP4

Each file type takes a different path. The queue shows the plan before anything runs.

.VOB → MP4

DVD home movies

MPEG-2 video with AC-3 or MP2 sound, usually interlaced and widescreen. Re-encoded and deinterlaced with the correct 16:9 shape.

.MTS → MP4

Camcorder clips

AVCHD and M2TS recordings already hold H.264, so they are remuxed in seconds. AC-3 audio becomes AAC.

.AVI → MP4

Old Xvid and DivX files

MPEG-4 Part 2 video and MP3 audio from the 2000s, re-encoded to H.264 and AAC for phones and editors.

.MKV → MP4

Recordings and downloads

MKV, MOV and TS files with H.264 are remuxed losslessly; WebM and HEVC can be re-encoded or kept.

How it works

Convert MPEG to MP4 in three steps

  1. Add your videos

    Drop up to 10 MPEG, VOB, TS, AVI, MOV or MKV files. Each file is read in your browser to show its container, codecs, size and length.

  2. Check the plan

    Files that already hold H.264 video are remuxed in seconds with no quality loss. Everything else is re-encoded to H.264 and AAC with the quality you choose.

  3. Download MP4s

    Preview each result, download it, grab every file in one ZIP, or send a clip straight to the splitter, compressor or GIF maker.

What each format becomes

The container is only the wrapper. What decides the speed is the video codec inside it.

MPEG to MP4 questions

How do I convert an MPEG video to MP4 for free?

Choose or drop your MPEG, MPG or VOB file above, check the plan shown for it, then select Convert to MP4. The conversion runs in your browser, so there is no upload, account, watermark or file count limit beyond 10 files per batch.

Is MPEG-4 the same as MP4?

Not quite. MPEG-4 is a family of standards. MP4 is its file format (MPEG-4 Part 14), which usually holds H.264 video and AAC audio. Older files labelled MPEG-4 often contain MPEG-4 Part 2 video (Xvid or DivX), sometimes inside AVI. This converter re-encodes that video to H.264 so the MP4 plays on phones, browsers and editors.

What does remux mean, and why is it so fast?

Remuxing copies the existing video and audio streams into a new MP4 container without decoding them. It takes seconds and keeps the original quality. It is used when a file already holds H.264 video, as most TS, M2TS, MKV and MOV recordings do. MPEG-1, MPEG-2, Xvid, WMV and similar video has to be re-encoded.

Will converting to MP4 reduce the quality?

A remux does not change the picture at all. A re-encode is very close to the original at the High setting; Balanced is a good default, and Smaller file trades some detail for size. Interlaced DVD and broadcast footage is deinterlaced so motion looks smooth instead of combed.

Can I convert DVD VOB files?

Yes, VOB files copied from an unprotected DVD convert like any MPEG-2 file, and widescreen DVDs come out with the correct 16:9 shape. A DVD splits one title into several VOB files of up to 1 GB, so convert the parts you need (up to 200 MB each). Copy-protected discs are not supported.

Are my videos uploaded anywhere?

No. Files are read and converted on your device with a video engine that runs in the browser tab. Nothing is sent to a server, and closing the tab discards everything that you have not downloaded.

What are the limits?

Each file can be up to 200 MB and 10 minutes, and one batch holds up to 10 files (1 GB in total). Remuxing works at any resolution up to 4K. Re-encoding is limited to about 3 minutes of 1080p or 10 minutes of DVD-size video per file, because it runs on a single browser thread.
