The short answer: remove time before removing pixels

If you want to make a video smaller without losing too much quality, start by trimming the parts nobody needs. Removing 20 seconds from a 60-second clip is cleaner than forcing the full minute through harsh compression.

HappyConvert handles compression locally in the browser. That is useful when you do not want to upload private footage, but it also means large files depend on your device memory, CPU, and browser stability.

The compression order I would use

• Trim the beginning and ending first. Intros, dead air, and repeated takes are pure file size.
• Keep the original resolution if text readability matters, especially for screen recordings.
• Drop from 1080p to 720p when the video is mostly people, scenery, or social sharing footage.
• Use a short sample export before processing a long file.

What settings matter most in a browser compressor

Duration, resolution, codec, bitrate, and frame rate decide most of the final size. Duration is the easiest win. Resolution is the next big lever. Codec choice matters too, but it can increase processing time because the browser has to encode the video locally.

For normal sharing, MP4 is the safer output. WebM can create smaller web-friendly files in some cases, but MP4 is easier when you are sending the result to clients, classmates, or coworkers who may use different devices.

When a few hundred megabytes is the wrong job for the browser

Browser-side compression is good for quick clips and privacy-sensitive files. It is not the most comfortable path for a few hundred megabytes of 4K footage, long meetings, or high-frame-rate recordings.

If a job takes several minutes for a 13 MB video, a few hundred megabytes can take much longer on the same machine. In that case, I would either trim first, use a shorter export range, or move the heavy batch job to a desktop FFmpeg workflow.
