About WebM

WebM is an open, royalty-free video format developed by Google and based on the Matroska container. It holds VP8, VP9 or AV1 video with Vorbis or Opus audio.

It is made for the web: all major browsers play it in the HTML video element, and it is common for screen recordings and short clips.

WebM allows only its own small set of codecs, so H.264 video or AAC audio has to be re-encoded to fit.

Convert WebM to 3GP online free, no account required — 3GP is an older mobile-phone video format.

Change WebM to 3GP without losing quality — convert WebM to 3GP free in your browser.

Why can't I upload my WebM video to Instagram or TikTok? Social apps almost always demand MP4, so a WebM made for the web needs converting before it will upload.

About 3GP

3GP is a container format defined by the 3GPP for mobile phones. It is a simplified relative of MP4 that typically holds H.263 or H.264 video with AMR or AAC audio.

Videos recorded on older mobile phones, especially before smartphones.

3GP videos are usually low resolution and heavily compressed, and converting them cannot add detail.

Why convert video to 3GP? Almost only for very old feature phones with tiny screens; any smartphone plays MP4 instead.
