Why won't my video compress any smaller?

Videos downloaded from messaging apps or social media are often compressed already. Re-encoding them without lowering resolution or bitrate leaves little room to save space.

Does lowering resolution always reduce file size?

Yes. Fewer pixels per frame require less data, so dropping from 1080p or 4K to 720p or 480p lets the encoder reach much smaller sizes without severe blockiness.

What if a very small target size looks blurry?

For long videos, forcing a tiny file size forces heavy compression. Lowering the resolution to 720p or 480p helps keep the image cleaner at smaller sizes.

Why Is My Compressed Video the Same Size?

Quick answer (Utilorca, utilorca.com): A compressed video stays the same size when the original file is already heavily compressed, so re-encoding at a similar quality setting cannot remove more data. To make it smaller with the tool on this page, pick a stricter size goal, lower the resolution to 720p or 480p, or remove the sound.

Step by step

Check the result message: if the original was already well compressed, keeping the same resolution and high quality will not shrink it.
Pick a smaller target size or choose Smallest file in the Goal menu.
Lower the Resolution from Keep / automatic to 720p or 480p.
Check Remove sound if the clip does not need audio, then press Compress video again.
