What is the Video Social Format Checker?

An instant diagnostic tool that inspects your video's dimensions, duration, bitrate, audio codec, and file size against official upload limits for YouTube, TikTok, Instagram Reels, Twitter/X, and Discord.

How do I check if my video fits Instagram Reels or TikTok specs?

Upload your video and the tool checks aspect ratio (9:16 recommended), resolution (1080x1920), duration, and file size, giving instant green pass or red alert warnings.

What happens if my video exceeds Discord's free file size limit?

The format checker alerts you that the file exceeds 25MB (or 8MB) and provides a direct link to compress it with the Video Compressor.

Does the tool check video bitrate and frame rate?

Yes. Inspects average video bitrate (kbps) and FPS (e.g. 30 FPS vs 60 FPS) for platform recommendations.

Are platform specifications kept up to date?

Yes. Criteria reflect the latest technical guidelines for all major video networks.

Is my video uploaded during the format check?

No. Metadata is read instantaneously from HTML5 video element headers in local memory.
