What the SSL Checker does
SSL Checker: checks Status and Notes from HTTPS URL.
From HTTPS URL, this tool derives Status and Notes. Enter what you need and trigger it when you are ready.
Most of these tasks are one-liners in a terminal, but not when you are away from one. That is usually what brings people inspecting an API response here.
There is no account, no upload and no server round trip, because the page does the work itself.
The method, a field-by-field reference and a worked example built from the defaults are all on this page.
What do the SSL Checker fields mean?
The SSL Checker uses 1 input. Every field is populated on load; treat those numbers as a template rather than a suggestion.
| Field | What to enter | Default |
|---|---|---|
| HTTPS URL | required | https://example.com |
How does the SSL Checker work?
Each output is derived from the inputs above in a single pass; there is no hidden state carried between runs, so the same inputs always give the same check.
Validation is deliberately strict: silently coercing a bad value is how wrong numbers get trusted.
What a typical run looks like
You provide: HTTPS URL
What happens: the file is read into memory by your browser, processed locally, and offered back as a download. It is never uploaded.
You get back: a download link for the new file and a short note on what changed.
Timing comes down to your own hardware, and the practical size limit is how much memory the browser will hand the tab.
How to use it
- Fill in HTTPS URL.
- Press Check.
- The panel reports Status and Notes.
- Share the link rather than a screenshot. It carries the values with it.
What this tool does not do
- Output follows the common convention for this format; a specific toolchain may have its own house style.
- Processing happens in your browser, so extremely large inputs are bounded by available memory.
- There is no audit trail: if you need one, record the inputs alongside the output.

Nothing leaves your machine. The only network traffic is loading the page itself.
It is free to use, with no premium tier holding back the useful parts.
It matches what you would get working it out by hand, with fewer opportunities to slip.
