How to reduce video size without losing quality
October 24, 2026 1 min read
Even a one minute phone video can be hundreds of megabytes. To email it, send it on WhatsApp or upload it to a site, you need to shrink it. Here are five methods, from most to least effective.
Compress videoShrink video size while keeping quality.1. Compress the video
This is the most effective method. Phones record at very high bitrates; compression removes data you won't notice and often cuts the file in half or more. Medium is a good balance of quality and size.
2. Lower the resolution
If you'll watch a 4K video on a phone, 1080p or 720p is more than enough. Halving the resolution cuts the pixel count to a quarter and shrinks the file a lot.
3. Trim what you don't need
Cutting the empty seconds at the start and end makes the file smaller and the video better. Size grows with length: half the length means roughly half the size.
4. Shrink it under a specific size
If an app has a size limit, like 25 MB for email attachments, picking a target size is the safest option. The tool calculates the best quality that fits based on the video length.
5. Remove the audio
If you don't need the sound, removing it makes the file a little smaller. It won't make a big difference on its own, but it helps alongside the others.
Which should I choose?
Compression alone is enough most of the time. If it's still big, lower the resolution; if it must fit a limit, use a target size. All tools run in your browser and your video is never uploaded.
