Video Compressor Online

It reduces file size by encoding video more efficiently or removing data you’re unlikely to notice. A well-compressed file can look almost the same but take up several times less space, making it easier to store, upload, and share.

Yes, if you choose lossy compression. However, with the right bitrate and modern codecs, quality loss can be almost unnoticeable. You can also use lossless presets – they will keep the quality, but the file will still be larger than a lossy one.

AV1, HEVC (H.265), and VP9 compress best – they deliver high quality at low bitrate. H.264 is slightly bigger, but works for every program and device. For minimal file size, choose AV1 or HEVC (make sure it’s supported by your device).

Usually, it can become 40-80% smaller with little or no visible quality drop. Smooth talking-head videos compress more, fast motion/sports – less. It is recommended to preview a sample before converting your entire video.

For a video in Full HD, use:

• 12000-8000 Kbps – very high quality
• 8000-5000 Kbps – balanced
• 5000-2500 Kbps – lightweight and acceptable for uploading online

Lower bitrate means smaller file and possibly more visible artifacts.

For uploading videos online, choose H.264.

If you want smaller file size, choose HEVC or AV1.

Platforms like YouTube re-encode all uploaded files, so stable bitrate and clean source input matter more than the format itself.

Use lossless presets or keep the bitrate high enough. Lossless presets will still reduce a file’s size by 20-40%, but not drastically. For near-lossless results, use HEVC/AV1 at a high bitrate – it gives small files with cleaner picture.

Yes, most tools (Movavi included) support batch compression. You can apply the same codec, bitrate, and resolution settings to multiple files at once.

Yes, if you reduce audio bitrate or re-encode your video file using lossy settings. To keep audio clear, use AAC/256 Kbps or convert it to FLAC inside the video (but this will affect the resulting size).

If you compress them locally – you’re perfectly safe. Your files stay on your device and are not uploaded to third-party servers, unless you do it manually.
