MP4 Cutter FAQ
How precisely can I place the start and end points?
+
You can type exact timecodes rather than only dragging, and the preview scrubs to the position as you move it. How exact the result can be depends on the format: some allow a cut anywhere, others snap to the nearest frame or keyframe.
Can I remove a section from the middle instead of keeping one?
+
Yes — cut the piece before it and the piece after it, then merge the two results. That is deliberately two steps because it keeps both halves on the fast, lossless path instead of forcing a full re-encode.
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.
How does MP4 Cutter cut the file?
+
Concretely, the cut is made at the nearest keyframe and the streams are copied through, which makes it near-instant; frame-exact cuts need the picture re-encoded, so the tool tells you which one you are getting rather than quietly picking. You set the start and end points on the waveform or the timeline and keep what is between them.
Can I run MP4 Cutter on several MP4 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 MP4 Cutter cost anything?
+
No. MP4 Cutter is free without an account, and the output carries no watermark, no corner logo and no intro card. Uploaded video is deleted from the workers shortly after the job completes.
What can I upload to MP4 Cutter?
+
MP4, MOV, MKV, WebM, AVI, WMV, FLV, 3GP, M4V, MPEG and MPG. The container and codec are probed before anything runs, so a mixed batch is handled correctly per file rather than assumed to be uniform.
Will MP4 Cutter lower the quality of my MP4 videos?
+
It depends on whether the job needs a re-encode. Operations that only touch the container or the timeline are done as a stream copy and the picture is bit-identical to the source. Anything that has to redraw frames goes through x264/x265 at a quality level you set, where CRF 23 is visually transparent on most footage.
Does MP4 Cutter belong on a site about a photo format?
+
JPEG.to is built around the format that carries nearly every photograph in existence — thirty years old, opened by literally everything, and still the right default for a photographic image. The jobs people bring here are the ones a photograph collects over its life — too big to email, wrong dimensions for a form, wrong way up out of a phone. MP4 Cutter runs on the same upload and the same account as the conversions because that is where those jobs land.
What is the sensible next step after MP4 Cutter?
+
The converter on this site moves images to and from JPEG, PNG, WebP and HEIC, which is where the trade between file size and one more generation of loss gets settled. Deciding the format last rather than first is the whole point: every extra save of a photographic image is another generation, and the fewer of them you spend, the more of the picture survives.
Is this the same engine as the other converter sites?
+
Yes — the same libraries, the same workers, the same caps. The difference is which advice is on the page, and here that advice is built on one property of the format the site is named after: the .jpeg and .jpg extensions are the same bitstream, so nothing here behaves differently from a .jpg — only the filename changes.
Is anything kept, and do I need to sign in?
+
Nothing is kept and no account is needed. Uploads are removed from the workers shortly after the job finishes; nothing is looked at, listed or indexed. An account buys history and larger batches, not access.
