Meridian Media › WEBM to MP4
WEBM is the video format of browsers and screen recorders. iPhones, many editors and messengers handle it poorly, while MP4 works everywhere.
How to convert WEBM to MP4
- Click “Select files” or drag a WEBM video into the box.
- Make sure MP4 is selected on the right.
- Click “Convert” — the MP4 will be saved to the Downloads folder.
How long does the conversion take?
WEBM is always re-encoded to H.264 at the original resolution. The time depends on length and resolution: video up to 720p is usually ready faster than it plays, Full HD and above takes longer. Video length is not limited.
Can I do the reverse, MP4 to WEBM?
Yes. Upload an MP4 and choose WEBM on the right: the video will be VP9 with Opus audio.
Formats
- From video (MP4, MOV, MKV, WEBM, AVI, FLV, M4V, MPEG, VOB, 3GP, WMV) — to MP4, MOV, M4V, AVI, WEBM, FLV, MPEG, VOB, GIF and to audio: MP3, M4A, AAC, WAV, FLAC, AIFF, OGG, OPUS, WMA, MP2, AC3.
- From audio (MP3, M4A, AAC, WAV, FLAC, AIFF, OGG, OPUS, WMA, MP2, AC3) — to MP4 with a black background and to other audio formats.
- From GIF — to MP4.
Limits
- You can select several files at once, each up to 1 GB. Files are converted one after another.
- Video length is not limited — only the file size matters, up to 1 GB. H.264 video is repacked into MP4, MOV, M4V and FLV in seconds.
- A GIF is made from the whole video: 8 frames per second, 360 pixels wide. WAV, FLAC and AIFF — up to 1 hour of audio (about 10 MB per minute).
File safety
The uploaded file is used only for the conversion and is never shared with anyone. The original file is deleted right after processing. The converted file is kept for 24 hours — during that time you can download it again — and is then deleted automatically.
