CheckClip — will your video pass on each platform?
Drop a video file and instantly see whether its length, aspect ratio and file size fit YouTube Shorts, TikTok, Instagram Reels and X — including the throttle rules the spec tables skip (a Reel can upload at 20 minutes and still never be shown to new viewers past 3).

Platform fit
Limits verified August 2026 against current platform documentation — platform rules drift, so re-check before a big launch. X figures are for a standard (non-Premium) account.
What this can and can't tell you
Your video never leaves your machine. The page reads the file's metadata with your browser's own video engine and makes no network request after it loads — check the Network tab while you use it.
This checks everything a machine can measure. What it can't judge is whether the video is any good — hook strength, pacing, whether the first two seconds earn the next ten. That's a human read. If you want honest, scored notes on the content itself, that's a thing we do: email the link to tim@leuklogic.com.

internal tools, Discord and Slack bots. Fixed price, quoted before work starts, usually $100–$500.
We build these regularly — CSV tools, converters, calculators, all free and all running
entirely in your browser. Drop your email and we'll tell you when a new one goes live.
