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 is the video from my old phone so tiny and pixelated? 3GP was built for small low-resolution phone screens on slow mobile networks, so there is no detail in the file to recover — the source simply never had it.
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.
Why convert video to WebM for a website? Browsers play it without plugins, and VP9 or AV1 compresses smaller than H.264 at the same quality, so pages load faster.
