MPG Cutter FAQ
Does the format limit where I can cut?
+
It does. MPG is the same MPEG-1/2 program stream under the shorter extension, still the format of DVD-era captures. That is precisely what decides whether a cut can be placed arbitrarily or has to land on a structural boundary.
Anything specific to MPG when trimming?
+
Yes — a .mpg is the same program stream as .mpeg, and both come out of DVD-era capture hardware with interlacing still baked in. It explains most of the "the cut is a fraction of a second off" surprises.
How does MPG 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.
What can I upload to MPG 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.
Is there a file size limit on MPG Cutter?
+
Yes: free accounts process video up to 40 MB per file, by far the most generous cap on the site; ffmpeg with x264, x265 and libvpx does the work, which is the same toolchain behind most desktop video software. Video is the one family where the cap is high enough that upload time, not the limit, is what you will actually notice.
Why would a modern-format site run MPG Cutter?
+
WEBP.to is built around the modern replacement for both of the old defaults: one format that does lossy, lossless, alpha and animation, and reliably lands smaller than the JPEG or PNG it came from. People arrive here having decided the old defaults are costing them bandwidth, and that decision immediately raises the rest: what size, what quality, what happens to the transparency. MPG Cutter is on the same upload and the same account so those questions get answered in one place.
Once MPG Cutter has run, what is worth doing next?
+
The converter on this site moves images to and from WebP, PNG, JPG and AVIF, which is where you decide whether a smaller file is worth losing the older browsers. Doing it in that order matters: pick the pixels first and the container afterwards, because the container is the cheap decision and the pixels are the expensive one.
Do the sibling sites run something different?
+
The engines are identical — same libraries, same workers, same caps. What is different is the opinion attached, and the opinion here rests on a property of the format this site is named after: the same .webp extension can hold a lossy VP8 frame, a lossless one, or an animation, so the sensible processing path is decided per file rather than per extension.
What happens to my file, and is an account required?
+
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.
