Social platforms compress videos again after upload. If you upload a huge unoptimized file, the platform may take control of the quality and create a softer, blockier result than you expected.

A better workflow is to prepare a clean, reasonable MP4 before upload. Start with the online video compressor, or choose a platform-specific page for your destination.

General settings for social uploads

Use these settings for most social videos:

  • Format: MP4.
  • Codec: H.264 for broad compatibility.
  • Resolution: 1080p for feed posts, 720p when upload speed matters more.
  • Aspect ratio: match the destination before you compress.
  • Audio: AAC is the safest default.
  • Bitrate: use enough bitrate to keep motion clean, but avoid giant files that trigger extra processing.

If your source file is MP4, start with compress MP4 online. If your main issue is size, use reduce MP4 file size.

Instagram, TikTok, and Shorts

Short vertical videos should be easy to upload and quick to start on mobile networks.

For these platforms:

  • use a 9:16 vertical frame
  • keep the final video short and focused
  • avoid extremely high bitrates
  • check captions and on-screen text after compression

Use compress video for Instagram for Reels and feed posts, or compress video for TikTok for short-form uploads.

YouTube and long-form video

YouTube can handle larger uploads, but that does not mean every file needs to be massive. A cleaner 1080p MP4 is often enough for tutorials, product walkthroughs, webinars, and talking-head videos.

Use compress video for YouTube when you want faster uploads while keeping a high-quality result.

Facebook and X / Twitter

For Facebook and X, reliability matters. Smaller files are easier to upload from mobile, less likely to fail, and faster for viewers to load.

Use:

If you need a predictable target, try compress video to 100MB or compress video to 200MB.

Before you upload

Check these details after compression:

  1. The opening seconds still look sharp.
  2. Text overlays are readable on a phone screen.
  3. Fast motion does not break into blocks.
  4. Audio is still in sync.
  5. The file is comfortably below the platform limit.

FAQ

Should I upload the largest file possible?

Not always. A very large file can take longer to upload and may be recompressed heavily. A clean, optimized MP4 is usually more reliable.

Is 720p enough for social media?

Often, yes. For mobile-first videos, a good 720p file can look better than a badly compressed 1080p file.

Can I compress video for social media online?

Yes. Use the video compressor or choose a focused page such as the Instagram video compressor, TikTok video compressor, or YouTube video compressor.
