How to compress a video on desktop

Use our fast video size reducer for desktop for large files like HD movies, batches of clips, or footage. Most free online video compressors are too slow for large files such as HD movies, batches of clips or footage, and will time out.

It can also compress all your videos in one run, in many formats like MKV, MOV, AVI, FLV, etc. Make your videos a lot smaller without losing too much quality. It can handle any file size and doesn’t have the limitations of a browser.

Step 1. Add your video files

Open the app and click Add Media, then choose Add video. This video file compressor lets you pick one clip or many at once. This is perfect if you need to perform batch video compression to save yourself some time.

Step 1. Compress video on PC or Mac.

Frequently asked questions

How do I compress video without losing quality?

All compression trims some data, but you can get remarkably close to lossless compression. Use a high-quality preset and the video codec H.264. Your footage will stay sharp enough that you won't even notice a difference.

What is the best video format for compression?

MP4 is the clear winner. It is a super efficient format that plays well with any MP4 compressor. Your clips stay lean without sacrificing clarity. It works on basically every phone, laptop, or social app.

Is it safe to upload my videos to this online compressor?

Absolutely. It is a safe video compressor that takes your privacy seriously. Files move through an encrypted connection. They are wiped from the servers shortly after you are done.

How do I compress a video for an email?

Typically, email services like Gmail, Outlook, and Yahoo Mail limit attachments to 20-25 MB. For this reason, it is recommended to lower the resolution (e.g. from 1080p to 720p) and/or the bitrate and to use a more efficient codec. For very short video clips, a file size of around 10-15 MB is usually sufficient. Use H.264 instead of H.265 or ProRes when exporting a video for an email. However, even after compression, the file can still be too large. In such cases, it is better to upload the video to a file-sharing service (Google Drive, Dropbox, WeTransfer, etc.) and then to send a link to it in the email. This way, the video is not recompressed by the email provider and thus retains its original quality.

How do I reduce video size for WhatsApp or Discord?

These apps usually have a 10 MB or 25 MB limit. You can resize a video online by dropping the resolution slightly. Slide the bar until you hit that sweet spot. This makes your video upload instantly without lagging.
