How to compress YouTube videos:
Shrink Your Videos for YouTube
Keep Video Quality
Compressing makes a new file and leaves your export where it is. The full-quality version stays on your drive for a re-cut or a different platform later, so a fast upload never costs you the good copy.
Upload Files Faster
A long export can sit uploading for hours on a home connection, and nothing goes live until the last of it lands. Compress first and the same video goes up in a fraction of the time, using a fraction of the bandwidth.
Process Files Locally
Our video compressor runs on your own machine. That means you are not sending the same footage across the internet twice, once to a service and once to YouTube, just to save time on the second trip.
Handle 4K Footage
Phones and mirrorless cameras record 4K at bitrates built for editing rather than uploading, so the file off the card is far bigger than YouTube needs from you. Compression trims that back before the upload starts.

Who This Is For
Marketers
A campaign is never one video. Between regional channels and shorter edits, you upload the same footage several times over, and every one of those runs is quicker from a compressed file.

What are the best compression settings for YouTube?
YouTube recommends MP4 with H.264 video and AAC stereo audio, at the same resolution and frame rate you shot in. Those are the settings Flixier exports to, so the smaller file matches what the platform expects rather than forcing it to work around your export.
What video formats can I compress for YouTube?
MP4, MOV, AVI, MKV, and WebM all work with our on-page compressor without converting anything first, which covers most cameras, phones, and screen recorders. If you would rather start from a format-specific page, there’s a dedicated MP4 compressor and MOV compressor for the same job.
Is there a size limit when compressing for YouTube?
Flixier does not impose one. You can process massive files without worrying about strict upload caps, provided your device has enough memory to handle the video data during the compression.
Does compressing hurt my YouTube video quality?
Some quality is always lost because compression works by discarding data. Flixier targets the redundant information a viewer will not notice and leaves the visible picture as close to the source as possible. You choose the resolution to control the exact trade-off.
Can I edit my video before uploading it to YouTube?
Yes. Open the compressed file in the Flixier editor to cut mistakes, add text overlays, generate subtitles, or lay in an audio track before you publish. Export from there and the compression stays applied, so you are not shrinking the same video a second time.
