Check video descriptions before upload
YouTube descriptions can include summaries, links, chapter timestamps, credits, hashtags, and calls to action. The hard limit is 5,000 characters, but the opening lines matter most because viewers see them before expanding the full description.
This checker is built for YouTube creators, faceless channel operators, Shorts creators, and YouTube automation teams who want quick upload QA without using a generic text counter. It counts characters, previews the first lines, checks links and hashtags, and flags chapter timestamp issues.
The 5,000-character description limit and first-lines guidance are based on YouTube's description guidance. The tool does not predict rankings or traffic; it helps you publish a cleaner description.
How to use it
Use it after drafting your description and before finalizing chapters, hashtags, links, and pinned comments.
Paste the description you plan to upload.
Add the target keyword if the video is search-focused.
Clean the first lines, links, hashtags, and chapters before publishing.
What the checker looks for
The goal is not to make descriptions longer. It is to make the top summary clear, keep supporting metadata organized, and avoid upload surprises when your description includes links, chapters, and hashtags.

FAQ
Is this YouTube description length checker free?
Yes. It runs in your browser, has no AI cost, and is fully free without signup.
What is the YouTube description character limit?
YouTube lists a 5,000-character limit for video descriptions. This checker counts your draft against that limit before upload.
Why does the tool preview the first lines?
The first lines are the part viewers scan before expanding a description. Put the video summary and most important context there before links or credits.
Does this generate a YouTube description with AI?
No. This tool is a deterministic checker. It trims spacing, counts characters, checks links and hashtags, and gives cleanup tips without sending your text to an AI model.
