What is 123apps?
123apps is a set of free online tools, including online-video-cutter.com, a video converter, an audio cutter and PDF tools. Files are uploaded, processed on its servers and returned for download.
123apps tools upload your video to their servers, then hand it back. CutFast runs the same everyday jobs — cut, compress, convert, merge — in the browser tab, so a local file never waits on an upload bar.
123apps and CutFast cover the same quick video jobs. 123apps uploads your file, processes it on its servers and deletes it a few hours later. CutFast opens a local file in the browser tab and never uploads it. If you would rather not send a private recording to a server, or you are tired of waiting on upload bars, use CutFast.
123apps (online-video-cutter.com and its sister sites) is a good set of single-purpose tools. The difference is where the work happens.
Drop a file and CutFast opens it in a guest editor that keeps media in the browser. There is no upload progress bar for a file that is already on your laptop.
123apps says uploaded files are deleted from its servers a few hours after you finish. With a local file in CutFast there is no server copy in the first place.
Video, audio, GIF and image tools all live on cutfa.st, and each one opens on the file you drop. No hopping between sister sites.
The common 123apps jobs each have a CutFast page that opens straight into the tool.
Mark in and out points, crop to 9:16 or 1:1, rotate a sideways phone clip, and export the file.
Shrink a video under 25 MB for Discord or email, or convert MOV, MKV, AVI and GIF to MP4.
Extract the audio as MP3, cut an audio file, or join several clips into one video.
