What CRF value should I use?

For most footage, a CRF of 23 to 28 keeps quality high while cutting size substantially. Lower the number for higher quality, raise it for smaller files.

Is H.265 always better than H.264?

H.265 produces smaller files at the same quality, but encodes slower and is less compatible. H.264 remains the best default for sharing and playback.

How to compress video without losing quality

Video is usually the heaviest file type you deal with. The good news is that most videos are exported with far more data than the eye can use, so you can often cut the size by half or more with no obvious quality loss. This guide explains how.

1. Re-encode with a modern codec

The codec decides how efficiently your video is stored. H.264 is the safe, universal choice and plays everywhere. H.265 (HEVC) compresses about 30 to 50 percent smaller at the same quality, but it is slower to encode and less compatible. For most people, re-encoding to H.264 is the right balance.

2. Use CRF instead of a fixed bitrate

CRF (Constant Rate Factor) lets the encoder spend bits where they matter. Lower CRF means higher quality and larger files. A CRF around 23 to 28 is the sweet spot where the result looks essentially identical to the source while being much smaller. Pushing quality higher mostly adds bytes you cannot see.

3. Match the resolution to how it is watched

A 4K clip that will only ever be watched on a phone or embedded at 720p is wasting enormous amounts of data. Downscaling to 1080p or 720p when full resolution is not needed is often the single biggest size win.

4. Do it locally for privacy

Many online video compressors upload your footage to a server, which is slow and risky for private or client material. CompressEasy Desktop re-encodes video on your own computer with bundled FFmpeg, so nothing is ever uploaded.

5. Compare before and after

Always check the result. A good workflow shows the original size, the compressed size, and the percentage saved, so you can confirm the video still looks right before sharing it.
