Caption Line Length Checker
Use this tool when you need a quick, readable check of caption line length. Paste real working text, choose the options that match your situation, and review both the transformed output and the flagged details. The page runs locally in your browser, so it is useful for drafts, QA passes, and small data cleanups without setting up software or sending the text to an external service.

What this tool does
The result organizes the most useful findings for caption line length. It keeps the main output readable while the counters and downloadable table make individual items easier to verify.
The browser parses each relevant line or HTML element, applies the selected rules, and records passes, warnings, and unmatched cases without modifying the source file.
A clean automated result does not prove that the text is correct in every language, page context, or assistive-technology workflow.
Example
Load the sample, run the check, and compare the output with the source. The sample includes at least one case that shows how the selected rules are reported.
Use cases
- Review content before publishing.
- Check a localization or accessibility QA sample.
- Prepare a concise issue list for a teammate.
- Export structured findings for later review.
Tips for better output
- Use the exact text that appears in the interface.
- Keep surrounding context when meaning depends on it.
- Review unknown entries instead of guessing.
- Test keyboard and screen-reader behavior separately when relevant.
- Keep the original text available for comparison.
Processing details
All parsing and transformation happens with standard browser JavaScript. Results are created from the pasted text, the visible options, and the reference rules described on this page.
This tool cannot see visual context, confirm author intent, replace native-speaker review, or guarantee conformance with every platform and standard.
Frequently asked questions
Does this caption line length checker send my text to a server?
No. The page processes the pasted text in your browser and does not require an API key.
Can I use this result as a final accessibility or localization audit?
Use it as a practical first pass. Context, language conventions, browser behavior, and human review can reveal issues that a text-only check cannot.
What should I do with entries marked unknown or needing review?
Check the original source and its surrounding context, then confirm the intended meaning with the relevant standard or a subject-matter reviewer.
Can I upload a text or HTML file?
Yes. Use Upload file or drag a supported text file onto the input area. Processing stays in the current browser session.
Why might another tool give a different result?
Tools may use different reference tables, thresholds, parsing rules, or language assumptions. Compare the stated rules before deciding which result fits your work.
