What is the Resize MP4 tool?
+
This free online tool lets you resize MP4 video files quickly and easily, without installing any software.
What video formats are supported?
+
We support MP4 and many other video formats. You can also convert between different formats.
Is there a file size limit for MP4 files?
+
Free conversions have a size limit per file, set by the type of file, and the page tells you when a file is over it. A paid plan removes that limit, so much larger files can be converted.
Will this affect the quality of my MP4 file?
+
Our tool is designed to maintain the best possible quality while resizeing your MP4 files.
Can I resize multiple MP4 files at once?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Is the Resize MP4 tool free to use?
+
Yes, our Resize MP4 tool is completely free for basic usage. No registration required.
A yw'n gweithio ar ddyfeisiau symudol
+
Ydy, mae ein trawsnewidydd yn gwbl ymatebol ac yn gweithio ar ffonau clyfar a thabledi. Gallwch drosi ffeiliau ar iOS, Android, ac unrhyw blatfform symudol arall gyda phorwr modern.
Pa borwyr sy'n cael eu cefnogi
+
Mae ein trawsnewidydd yn gweithio gyda phob porwr modern gan gynnwys Chrome, Firefox, Safari, Edge, ac Opera. Rydym yn argymell cadw'ch porwr wedi'i ddiweddaru i gael y profiad gorau.
A yw fy ffeiliau'n cael eu cadw'n breifat ac yn ddiogel
+
Uploaded files are processed on our own conversion servers, nobody looks at them, and they are not shared. The upload and the converted file are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Beth os na fydd fy lawrlwythiad yn dechrau
+
Os nad yw eich lawrlwythiad yn cychwyn yn awtomatig, ceisiwch glicio'r botwm lawrlwytho eto. Gwnewch yn siŵr nad yw ffenestri naid wedi'u rhwystro, a gwiriwch ffolder lawrlwytho eich porwr. Gallwch hefyd glicio ar y dde ar y ddolen lawrlwytho a dewis 'Cadw Fel'.
A fydd yr ansawdd yn cael ei gadw
+
It depends on the formats. A lossless target such as PNG, WAV or FLAC keeps what the source holds; a lossy target such as JPG, MP3 or MP4 is usually re-encoded, which trades some detail for a smaller file.
Oes angen i mi greu cyfrif
+
Nid oes angen cyfrif ar gyfer defnydd sylfaenol. Gallwch brosesu ffeiliau ar unwaith. Mae creu cyfrif am ddim yn rhoi mynediad i chi i'ch hanes trosi a nodweddion ychwanegol.
