How to edit MP4 videos

How to edit MP4 videos
  1. Upload MP4 file

    Upload the video file you want to edit (or, you can use the video converter to turn another file format into MP4.) Upload directly from your computer, use the drag and drop feature, or paste in the URL of a video that’s hosted on a site like YouTube or TikTok.

  2. Edit MP4

    In the editor, choose from 100+ video tools like the video resizer, video enhancer, subtitle generator, and much more.

  3. Export and share

    When you’re done editing, click “Export” to export your project as an MP4. You’ll be able to save, store and upload your file wherever you like. You can also copy your project’s unique URL to share with friends, family, or colleagues to collaborate in real time.

The fastest, easiest-to-use MP4 editor online

Every major video file type supported 

Kapwing supports MP4 files, MOV videos, WMV, and more. With Kapwing’s video editor, you have access to more than 100 built-in editing tools. In a few clicks, you can resize and compress videos, create animated subtitles, remove video backgrounds, import content from URLs, and convert between images, videos, and GIFs. You also have access to a robust media library filled with royalty-free video clips, images, and audio tracks to create any type of content you need, for any platform you plan to share on.

Collaborate with your team, regardless of video format

MP4 video editing shouldn’t be a bottleneck for your creative team. Kapwing was designed to eliminate inefficiencies in your team’s video creation process and center it in one place where you can all create, review, and store content. Just share the project link for real time collaboration — you can even leave timestamped feedback right on the video itself. No more switching between multiple tools and platforms to move through your video creation process.

Save hours of time editing MP4 files

Kapwing saves you and your team hours of time by automating tedious editing tasks with AI. Use tools like SmartCut to remove silences from videos, convert text to speech, or generate videos, images, and memes. Plus, it’s all on the cloud, so your device’s storage and memory won’t be bogged down by clunky software. Just access all of your projects and assets from your personal media library. (Keep in mind that many of Kapwing’s editing tools are free, but some, like AI-fueled features, require an upgrade to the Pro version.)

Best online video service ever. And a miracle for deaf people.
[Subtitler] is able to autogenerate subtitles for video in almost any language. I'm deaf (or almost deaf, to be correct) and thanks to Kapwing I'm now able understand and react on videos from my friends :)

By the far the most user friendly software to use.
As a housewife at home looking to start a Youtube channel for fun with absolutely zero editing experience, it was so easy for me to teach myself via their YouTube channel. It takes the tediousness out of editing and encourages creativity. As long as Kapwing is around, I will be using their software.

Love this site.
As a English Foreign Language Teacher, this site helps me to quickly subtitle interesting videos that I can use in class. The students love the videos, and the subtitles really help them to learn new vocabulary as well as better understand and follow the video.

Excellent subtitling features
[It] works perfectly for me. Have been using Kapwing for a year or so, and their automatic subtitle tool gets better and better every week, it's rare that I have to correct a word. Keep up the good work!
