3GP Cutter FAQ
Is the part I keep re-encoded?
+
Not if the format allows a stream copy — the data you keep is bit-identical to the source and the job finishes in about the time the upload took. Only a frame-exact cut on a format that cannot do it cheaply needs a re-encode.
Does the format limit where I can cut?
+
It does. 3GP is the cut-down MP4 profile built for early mobile networks, usually very low resolution with AMR audio. That is precisely what decides whether a cut can be placed arbitrarily or has to land on a structural boundary.
Anything specific to 3GP when trimming?
+
Yes — 3GP files are usually very low resolution with AMR speech audio, so there is little detail left to protect and a lot of size to reclaim. It explains most of the "the cut is a fraction of a second off" surprises.
Can I run 3GP Cutter on several 3GP videos at once?
+
Yes. Uploads queue in parallel, which matters more here than anywhere else because video jobs are minutes rather than seconds. Free accounts run one file at a time; a pass lifts that.
Does 3GP Cutter cost anything?
+
No. 3GP Cutter is free without an account, and the output has no watermark, corner logo or intro card. The upload and the result are deleted automatically about 24 hours after the job, which leaves time to download the result.
Why does a WebM site host 3GP Cutter?
+
WEBM.to is built around the container the open web actually chose — VP9 or AV1 with Opus audio, decoded natively by every modern browser and needing no plugin, licence or player. Video is the case where extra round trips hurt most — the files are large and every upload costs real minutes. Running 3GP Cutter on the same pipeline as the conversions means one upload covers the whole job instead of one upload per tool.
What should I do with the result once 3GP Cutter is finished?
+
The converter on this site moves video between WebM, MP4, MKV, MOV and the rest, or pulls the soundtrack out entirely, without another upload. Sequencing it that way matters more for video than anywhere else: each re-encode is another generation, so the fewer of them stand between the source and the file you publish, the better it looks.
Is 3GP Cutter here the same tool the sibling sites run?
+
The engines are shared — the same ffmpeg build with x264, x265 and libvpx, the same workers, the same limits. What a WebM site adds is a view on containers and codecs: which combinations play everywhere, which need a re-encode and which can simply be copied across. It also starts from one fact about the format this site is named after: WebM is VP9 or AV1 with Opus audio, which browsers decode natively but which most desktop editors still transcode on import.
Do I need an account, and does anything get kept?
+
No account is needed. Uploads and results are kept for about 24 hours, which leaves time to download the result, and are then deleted automatically; nobody reads, lists or indexes them. Several files in one job need a paid plan.
