Change video resolution
Pick 720p, 1080p, 2K or 4K. Cutwisp converts the video in your browser and keeps the aspect ratio.
Your browser can't show a preview of this file. You can still set the times and convert it.
How it works
- Open your video file.
- Pick the resolution. Use the yellow handles if you only want part of the video.
- Click "Convert and save". The result is saved as an MP4 file.
Questions and answers
Is my video uploaded?
No. Cutwisp processes the file inside your browser. The video is never sent to a server.
Does 4K make my video sharper?
No. Cutwisp scales the picture up. It has more pixels afterwards, but the details stay the same as in the original. A 4K version mainly helps when a platform or a project asks for exactly that resolution.
Why make a video smaller?
A 4K video from a phone is large. At 1080p or 720p the file gets smaller. That helps when you send it by messenger or email, and it saves space.
What do 2K and 4K mean?
2K here means 1440p, for example 2560 × 1440 pixels. 4K means 2160p, for example 3840 × 2160 pixels. For vertical videos the numbers are swapped, for example 1080 × 1920.
Which files work?
MP4, MOV, MKV and WebM files in most cases. Your browser has to support the video format inside the file. Not every computer can encode 4K.
Does it cost anything? Is there a watermark?
Cutwisp is free, and it doesn't add a watermark.
