Video requirements for every major platform

Each social media platform has different rules for video size, format, resolution, and duration. Uploading a video that doesn't meet these specs results in compression, rejection, or poor quality. Here's what you need to know.

Instagram

FeatureMax File SizeFormatMax DurationAspect Ratio
Feed video250 MBMP4, MOV60 seconds1:1, 4:5, 16:9
Reels250 MBMP4, MOV90 seconds9:16
Stories250 MBMP4, MOV15 seconds per story9:16
IGTV650 MBMP4, MOV10 min (60 min for verified)9:16

Tips for Instagram:

  • Instagram re-compresses all uploads. Pre-compress to 15–20 MB for feed videos to minimize quality loss.
  • Reels perform best at 1080×1920 (9:16). Don't upload horizontal videos.
  • Keep Stories under 15 seconds or they'll be split into multiple parts.

TikTok

SpecRequirement
Max file size287 MB (mobile), 500 MB (web)
FormatMP4, MOV, WebM
Max duration10 minutes
Aspect ratio9:16 (recommended), 1:1
Resolution1080×1920 recommended

Tips for TikTok:

  • TikTok's compression is aggressive for files over 50 MB. Compress to under 50 MB for best quality.
  • Upload from desktop for the 500 MB limit — useful for longer videos.
  • H.264 encoding with AAC audio gives the best results.

YouTube

QualityMax File SizeRecommended Bitrate
1080p256 GB8–12 Mbps
4K256 GB35–45 Mbps
8K256 GB80–120 Mbps
SpecRequirement
FormatMP4, MOV, AVI, WMV, FLV, WebM
Max duration12 hours (or 256 GB)
AudioAAC or MP3, 44.1 kHz or higher

Tips for YouTube:

  • YouTube has generous limits, so focus on quality over file size. Upload at the highest quality you have.
  • Use MP4 with H.264 for fastest processing. H.265 (HEVC) is supported but processes slower.
  • For 4K uploads, expect 30+ minutes of processing time before the 4K option appears.

X (Twitter)

SpecRequirement
Max file size512 MB
FormatMP4, MOV
Max duration2 min 20 seconds
Resolution32×32 to 1920×1200
Frame rate30 or 60 fps

Tips for X:

  • X compresses videos aggressively. Keep files under 15 MB for minimal re-compression.
  • The 2:20 duration limit is strict. Use our video trimmer to cut your clip.
  • 720p uploads often look better than 1080p on X because of their compression algorithm.

Facebook

FeatureMax File SizeMax DurationAspect Ratio
Feed video4 GB240 minutes16:9, 1:1, 4:5
Stories4 GB20 seconds9:16

Tips for Facebook:

  • Facebook's compression is moderate. Files under 100 MB generally look good.
  • Upload in MP4 with H.264 for best compatibility.
  • 4:5 aspect ratio gets the most screen space in the mobile feed.

  2. Compress to under 50 MB — Use our video compressor to hit your target size.
  3. Trim to the right length — Use our video trimmer to meet duration limits.

FAQ

What happens if my video exceeds a platform's size limit?

Most platforms will either reject the upload or compress it automatically — often with poor results. Pre-compressing gives you control over the quality trade-off.

Should I upload 4K video to social media?

Only YouTube benefits from 4K uploads. Instagram, TikTok, and X will downscale 4K to 1080p anyway, so you're just wasting upload time. Stick with 1080p for these platforms.

Does social media reduce video quality?

Yes. Every major platform re-encodes your video to their preferred format and bitrate. The smaller your upload file, the less additional compression they apply. Pre-compressing to a reasonable size (15–50 MB) actually results in better final quality.

What video format works everywhere?

MP4 with H.264 video and AAC audio is universally supported. It works on every platform, every browser, and every device. Use our video converter if your video is in a different format.
